Everyone can be helped to hear better by using 3 simple secrets to better hearing.  This is true if you have normal hearing, a mild hearing loss that doesn’t require hearing aids or a more significant loss that does require them.  In this article I will discuss how you hear; disclose the 3 simple secrets to better hearing; and show you how to apply them in difficult situations such as restaurants, parties, and family gatherings.  I will also give you some important tips to improve family communication at home.

Hearing Happens In Your Brain, NOT your Ears!

Before we start, the first thing you must understand is that hearing happens in your brain, not in your ears!  The ears send the message to your brain, where the information is combined with what you see and what you expect to hear.  After the brain puts it all together we say that “we hear and understand what is said”.  Some of the listening tips are going to deal with your ears, some with your eyes, and still others with your brain.  We hear best when all three of these are working together and helping each other. 

Secret #1: Reduce the Background Noise

The quieter it is, the better you are going to hear.  So, reduce the noise!  This is actually easier than you think.  You can turn the TV down or off or choose to have conversations during the commercials and use the mute button.  You can turn the faucet off. Water is a great masker of speech.  Everyone has trouble hearing and understanding over the sound of running water.  You can go into a quieter area or another room to get away from the noise.  You can also move out of the center of a room and get near the wall.  In large rooms the center is the noisiest area and the closer you are to the walls the quieter it gets.

Secret #2: Watch the Person Speaking

Your eyes and ears work together to give your brain the information it needs to “hear and understand”.  Use your eyes to help you ear better.  You can move in front of the person who is speaking so you have a clear view of their face.  This helps you lip read as well as watch for facial expressions which add so much to our understanding of speech. You can ask the speaker to look at you and if necessary to move their hand away from their face.  If they turn and start to walk away while they are still talking, ask them to come back and finish the conversation face to face. 

Secret #3: Pay Attention

This is the brain part.  Hearing happens in your brain and most of us cannot actively listen and understand speech while we are doing other things.  So please, give the conversation your full attention by muting the TV, putting down the book you were reading, looking up from the newspaper, and stop knitting.  If you give the conversation 100% of your attention you will hear much better.

Special Situations:  Here are some ways that you can apply these secrets to special situations.  By using the 3 secrets correctly you can maximize your understanding of speech even in very noisy places! 

CARS:  Cars are one of the most frequent difficult situations that you need to deal with. There is the car, traffic and wind noise.  You also need to be watching the road and concentrating on your driving so it is hard to concentrate on listening.  Here are some things you can do that will make life a little easier:

1. If you wear hearing aids you can try turning the one that is against the window down or off.  This will reduce the noise of the car and the traffic.  If you have hearing aids in both ears you may want to turn the one that is to the center of the car up a little to help you hear the radio and the conversation more easily.  Try different combinations and see what works best for you.

2. When giving, or receiving directions, wait until a stop sign or a red light.  While the car is stopped you can look at the person speaking and give your full attention to the conversation.    

3. Drive with your windows rolled up.  Wind noise is very hard to hear over.  You can try keeping a back window cracked slightly to help you hear sirens and other warning sounds. 

4. If you need to really converse with people in the car the best seat is the front passenger’s seat.  This allows you to rotate your body slightly so your right ear is not up against the window, and your left ear is rotated slightly toward the back seats.  If you are the driver, please forget trying to have a conversation while you are driving.  Remind your passengers that their safety is your most important concern.  Ask them to talk to you only while the car is stopped and then only about really important matters.  You can save the long conversations for when you get to your destination. 

RESTAURANTS:  This is probably the place where older people have the most trouble. Almost everyone over the age of 55 years complains of not being able to hear well in this type of noise.  Unfortunately, in restaurants there are many factors you cannot control such as how loud or fast the server speaks or how noisy the table next to you is.  There are some things that are in your control and you want to be sure to use these to help you hear better.

1. Always ask for a table near the wall.  Never sit in the middle of the room where noise is coming at you for all around.  The noise will drown out what is happening at your table.  So choose your table wisely!

2. If you do not wear hearing aids then you should try to sit with your back near or against the wall.  This will reduce the noise coming from behind you and also make the voices of your guests across from you a little louder and easier to hear.  (This can make as much as a 70% improvement in your understanding of speech in restaurants.  Try it!) 

3. If you wear hearing aids with dual or directional microphones sit looking at the wall.  This will allow your hearing aids to do the best job of reducing noise.  If you are not sure about your hearing aids ask your fitter what type you have.  Using your directional hearing aids correctly can make a significant difference in how much you hear and understand in this type of difficult situation. 

4. Try to get a table in the quietest part of the restaurant.  Quiet areas are usually found along the wall, in corners, and away from the front door and kitchen access doors or work stations.  If you are not familiar with the restaurant take a walk through and listen for the quieter areas.  Then ask your hostess to seat you in that area.  An extra 10 minute wait to be seated is well worth it if you can now enjoy visiting with your party. 

PARTIES:   Parties are a lot like restaurants.  Being in control of the situation is key to successful hearing and understanding. 

1. Do NOT stand in the middle of the room.  You will get noise from all around you and will have the most trouble trying to hear and talk in the locations. 

2. Move toward the wall area.  If you wear directional or dual microphone hearing aids, put your friends with their backs against the wall and you can stand with your back to the room and looking at the wall.  If you do not wear hearing aids then stand with your own back to the wall and put your friends in a group around you looking toward you and the wall. 

3. Try to keep the groups you are visiting with small.  You will do best when the group is no more than 4 people at a time.  You will enjoy your event much more when you speak with several groups of 3-5 people rather than one large groups of 10+.  (Don’t forget to position yourself correctly relative to the wall as discussed in #2 above.)

AT HOME:  This is where we live and where we spend the most time each and every day.  By applying the 3 secrets of reducing noise, paying attention, and using our eyes you can really improve home communication. Several of our patients have told us that using these simple tricks at home really reduced communication stress and improved their marriages! So they are worth a try. 

1. Reduce Noise:  Put the TV on mute; turning the water off; closing the front door can all reduce noise and make conversing easier.  Look around and find your noise sources and then figure out how you can turn them down or off when you really want to communicate with your spouse or family. 

2. Move closer to the person who is speaking.  The closer we are the better we hear.  Don’t try to talk from room to room.  Sound waves are not that smart and they really do not travel well.  So go into the room where the speaker is, or have them come to you. 

3. Look at the person who is speaking.  This means you need to be in the same room and close enough that you can see them.  It also means that the speaker cannot turn around and walk out of the room while they are still talking.  We need face-to-face conversation to be able to hear and understand speech clearly!

4. Get the listener’s attention BEFORE you try to talk to them.  Your voice can easily blend into the TV or you may be too far away for them to even hear you.  Simply call their name and wait for a reply.  Once they say “what?” or “OK”  that is your signal to start talking.  If they do not answer when their name is called then don’t waste your breathe trying to tell them something.  Instead, move closer or go find them, or wait until later to speak to them.

Now Hear this…. Are You at Risk for a Hearing Loss?

Did you know hearing loss…

  • Is the third most prevalent chronic health condition in America, behind high blood pressure and arthritis?
  • Affects 36 million Americans (about 17% of adults)?
  • Is more common in men than women?
  • Costs our economy billions of dollars in lost wages and hidden costs annually?

Is not being adequately identified by healthcare professionals? Only 38 percent of adults ages 70 years and older and only 29 percent of adults ages 20 to 69 have had their hearing tested within the last 5 years!

Do you or someone you love have a hearing loss? If so, you’re not alone. Almost 20% of adults in the United States will develop hearing loss during the course of their lives, and if undiagnosed and untreated, its affects can be devastating. Impaired hearing can have a profound impact on emotional, physical, economic, and social well-being.  People with hearing loss have documented decrease in quality of life, reporting symptoms of depression, dissatisfaction with life, reduced functional health, and social isolation. Statistically, they have lower income levels, and frequently complain of frustration in relationships and various communicative situations, as well as inability to enjoy social situations, and fatigue. Despite the fact that most people with hearing loss can be helped with today’s state of the art amplification, many never seek help, or resist the use hearing aids or other assistive listening technologies.

The causes of hearing loss are varied and resultant impact on auditory capability may range from mild to pronounced. Sometimes the cause or etiology, such as wax build up in the external ear canal or an ear infection, is readily apparent. In other instances, the cause of hearing loss may be more obscure. Decreased hearing is often called “the invisible handicap”. Because hearing impairment (especially loss related to aging) often presents very gradually, those with significant hearing impairment can be unaware of their loss. Family members, significant others, co-workers and friends are frequently the first to notice communication problems related to decreased hearing sensitivity.

Given that 36 million Americans are faced with this “invisible handicap” what kinds of risk factors increase the likelihood that someone will develop hearing loss? Why do some people develop hearing loss and while others do not? Some risk factors are obvious, but others are much more obscure.

Perhaps the most widely recognized risk factor is aging. Presbycusis, or the loss of hearing that gradually occurs as we grow older, is a familiar scenario for those of us with older family members. In fact, about 30-35 percent of adults between the ages of 65 and 75 years have a hearing loss, while an estimated 40-50 percent of people 75 and older have a hearing impairment.

Loss associated with presbycusis is usually greater for high-pitched sounds, resulting in the frequent comment “I can hear people talking, but can’t understand them clearly”. It is most commonly binaural (in both ears), affecting the ears equally. Because this type of loss in hearing sensitivity is so gradual, people who have presbycusis frequently lose their frame of reference for normal loudness of sounds, and often do not realize that their hearing acuity is diminishing.

The resultant relationship dynamic is frequently the subject of jokes – “My husband suffers from ‘selective’ hearing and he’s driving me crazy”! In reality, however, hearing impairment is no laughing matter and can take quite a toll on communication with significant others. Research indicates that for couples where one person has unaddressed hearing loss, the divorce rate is actually significantly higher.

Most people would agree that we now live in a very noisy world. Noise levels for rock concerts, radios, motorcycles, traffic, industrial and lawn equipment, and even our personal listening devices constantly bombard our auditory system. It is not surprising that noise exposure is another one of the most frequently cited risk factors for hearing loss, and now rivals aging as the number one cause of hearing loss in this country.  Noise from occupational, recreational and sporting activities all pose significant hazards to hearing in the United States today. Firearm use is one of the biggest culprits in our area of the country. A single shot from a shotgun, experienced at close range, can permanently damage hearing.  Repeated exposures to loud machinery in the work place or as part of yard maintenance or recreational experience may, over an extended period of time, present a serious risk to hearing. Even something as seemingly benign as blow dryers for styling hair put hearing at risk.

Consider the noise levels for such activities as NASCAR, jet ski and power boat usage, and lawn equipment. The cumulative effects of these noise hazards and many others pose a serious risk for hearing. Noise exposure risk is a time weighted function – in other words, the longer the exposure time, the greater the risk, and lower the loudness level required to cause damage. According to the National Institute on Deafness and Other Communication Disorders (NIDCD), 10 million Americans have already suffered irreversible hearing damage from noise, and 30 million more are exposed to dangerous noise levels each day. A one-time exposure to hazardous noise resultant from gunfire or a rock concert, no matter how brief the time, of 120 dB or more can leave hearing permanently impaired. Prolonged exposure to only 85 dB (which can be generated by a commonly used appliance such as a blow dryer or hand held power tool) can do the same. 

Children and young adults are bombarded with potentially damaging noise exposure, most of which is easy to overlook. Most people intuitively recognize that “boom boxes”  IPODS, and other personal listening devices, if played too loudly, constitute a risk to hearing. However, consider the noise levels inherent to playing in a school band or orchestra. Students engaged in this commonplace activity spend hours practice in noisy environments within the context of their academic activities, yet many of them are not wearing appropriate ear protection, nor are schools effectively addressing this problem. To complicate matters, for reasons that are not fully understood some people are more susceptible to noise exposure than others.  As an example, research indicates that those with blue eyes are more prone to noise exposure than those with darker eye color!

Aging and noise exposure are two rather obvious risk factors for hearing loss, but there are many other factors that are more insidious. Studies suggest that there is a strong genetic component inherent to hearing loss, both for childhood deafness as well as presbycusic loss. If your parent or grandparent had hearing loss, your risk factor for developing a similar impairment may increase. If you had a relative who was hearing impaired from birth, family members of child bearing age need to be mindful of this risk factor, and be particularly vigilant with regard to insuring that the newest members of the family are effectively screened at birth for hearing sensitivity.

Various diseases of the ear certainly pose risk to hearing sensitivity. Ear infection, otosclerosis (a bony growth in the middle ear cavity), Meniere’s Disease, acoustic neuroma (a tumor on the auditory nerve), and a host of other maladies are obvious risk factors for hearing loss. But did you know that hearing loss is about twice as common in adults with diabetes compared to those who do not have the disease, according to a new study funded by the National Institutes of Health (NIH)? Visual deficits have long been associated with diabetes, but hearing loss is an under-recognized complication. Because of the strong correlation between diabetes and hearing loss, The National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), recently suggested that people with diabetes should consider having their hearing tested.

Use of common drugs such as antibiotics, aspirin, diuretics and chemotherapy can cause hearing loss. Typically, hearing loss from ototoxic drugs is high frequency, which often results in the hearing impairment less obvious to those it affects. All radiation and chemotherapy patients should insist on baseline hearing assessments before, during, and following their course of treatment to insure that auditory effects of ototoxic interventional strategies are carefully monitored and treated.

Race and gender also play a role in hearing loss risk factor determination. Researchers now know that compared to women, men are five and one half times more likely to have hearing loss. White and Mexican American men have a higher incidence of both high-frequency hearing loss and hearing loss in both ears than blacks, who were 70 percent less likely than white participants to present with hearing loss.

With the dramatic increase in airbag use, motor vehicle accidents (MVA’s) are common culprits for increased risk of hearing loss. In fact, 17% of those involved in MVA’s with airbag deployment will have permanent loss of hearing as a result. Other insidious risk factors for hearing loss include smoking and cardiovascular disease. The incidence of hearing loss is significantly more pronounced among smokers, as well as those with any type of cardiovascular disease.

Many healthcare professionals simply don’t make these associations, and as a result, do not refer patients for hearing evaluation as often as risk factors might dictate. So, the message is be aware, and be proactive in assessing your risk, or that of your loved one, for hearing loss. For a comprehensive audiometric evaluation, see a Board Certified Doctor of Audiology. If you’ve never had a baseline audiogram, it’s certainly in your best interest to do so. Only 38 percent of adults ages 70 years and older and only 29 percent of adults ages 20 to 69 have had their hearing tested within the last 5 years.   If you’re over 65, hearing evaluation each year by a Board Certified Audiologist should become part of your annual medical maintenance program.

New Smoke Alarm Requirements Will Save Lives

June 4th, 2010

As many of you are probably unaware, a new National Fire Alarm Code went into effect in January 2010.  The change is the result of mounting research evidence indicating that millions of Americans could potentially sleep through their smoke alarms during a fire.

Most standard smoke alarms in the US produce high-frequency tones between 3000 to 4000 Hz.  Unfortunately, this high-frequency range is also one of the first to be effected by hearing loss.  About 30 million Americans, or 1 in 10, have some degree of hearing impairment.  According to the National Institutes of Health (NIH), about 18 percent of adults ages 45-64 have hearing impairment, compared with 30 percent of adults 65-74 and almost 50 percent of adults over 75.

The new National Fire Alarm Code would require the use of a low-frequency signal (520 Hz) for fire alarms installed in residential bedrooms of those with mild to severe hearing loss by January 2010 and in all commercial bedrooms by 2014.  This low-frequency tone has been found to be significantly more effective in waking up individuals with hearing loss and those in a deep sleep, even more effectively than strobe lights or bed shaking devices alone.

Fire is the third leading cause of accidental death in the US.  Most fire fatalities occur at night, between the hours of about 10 p.m. to 7 a.m., when the vast majority of people are asleep.  The National Fire Protection Association (NFPA) reports that adults above the age of 65 have about twice the risk of fire fatality than the average and those over 85 have four and half times the risk.  These figures are especially troubling, given the fact that these groups are also at a much greater risk of not hearing their smoke alarms. 

If you or a loved one suffers from even a mild hearing loss, a traditional smoke alarm may not be enough to awaken you from a deep sleep.  Often times you only have a few minutes to escape a house fire once the alarms have detected smoke.  Serious consideration should be given to whether a low-frequency smoke alarm or some other form of alerting device would be the best choice for your needs in case of a fire.  Speaking with an audiologist will help you determine the most appropriate options based on your individual hearing needs.

Fire Facts from the NFPA:

  • In 2008, U.S. fire departments responded to 386,500 home fires. These fires killed 2,755 civilians. Eighty-three percent of all fire deaths resulted from home fires.
  • Someone was injured in a home fire every 40 minutes and roughly eight people died in home fires every day during 2008.
  • A fire department responded to a home fire every 81 seconds.
  • Almost two-thirds of reported home fire deaths in 2003-2006 resulted from fires in homes with no smoke alarms or no working smoke alarms.
  • About 1/3 of home fires and deaths happened in the months of December, January and February.
  • The kitchen is the leading area of origin for home fires. However, bedrooms and living/family rooms are the leading areas of origin for home fire deaths.
  • One-third of American households who made an estimate thought they would have at least 6 minutes before a fire in their home would become life-threatening. The time available is often less.
  • Smoke alarms that are properly installed and maintained play a vital role in reducing fire deaths and injuries. Having a working smoke alarm cuts the chances of dying in a reported fire in half.
