Healthy Ears Are Happy Ears

 

As we grow older, hearing loss is something we will all have to deal with in one way or another.   Human hearing deteriorates at different rates and severity for each of us.  As members of the audio community, it is extremely important for us to keep our ears in tip-top condition for as long as possible.  Here are a couple of tips to help your ears stay young and healthy.

Regular Ear Exams

Audio professionals should get their hearing checked at least once a year.  Hearing tests can be done with your physician during your annual physical, or by making an appointment with an audiologist.  If you are an avid industry convention attendee, chances are that there might be an audiology group providing free hearing screenings.  This has been the case over the years with AES, NAMM, USITT, and even LDI to name a few.  If circumstances prevent you from getting a hearing test in person, here are a few online options:

No Smoking

In 2019, Reuters News reported that smokers were 60% more likely to develop high-frequency hearing loss as compared to non-smokers.  Studies show that nicotine and cigarette smoke interfere with the neurotransmitters responsible for delivering sound information to the brain, irritate the Eustachian tube and lining of the middle ear, and can even cause tinnitus.  If you’re having a hard time quitting smoking, your physician can help map out a plan that works for you.  There are also many free resources designed to assist with quitting smoking.  Some of these are:

Ditch the Cotton Swabs

I have to admit that this one is hard for me.  I hate the feeling of anything in my ears, including water, so I definitely gravitate toward the Q-Tips right after a shower, but this is probably the worst way to clean your ears.  In fact, cotton swabs can make matters worse by pushing ear wax deeper into the ear, and they can even damage the eardrum.  Physicians and audiologists suggest towel drying the parts of the ear you can reach, and then cleaning out ear wax with an at-home irrigation kit or over-the-counter ear drops to lubricate and soften ear wax to prevent it from hardening and plugging up the ear canal.  If your ear becomes plugged with wax, and one of these methods is not doing the trick, your doctor can provide in-office irrigation.  BTW, there is no science behind the effectiveness of ear candles, and actually, some studies have shown that ear candles can cause an increase in wax due to candle wax deposits.  So, if you’re thinking that this will be a fun and natural solution for cleaning your ears, think again and stick with science.

Keep Them Covered

We all know that we need to be wearing earplugs or earmuffs at concerts, but loud music is not the only thing that will damage your ears.  If you have to yell over a noise to be heard, it’s too loud for your naked ears.  Construction sites, home power tools, electric yard tools, and even areas with high human population (farmer’s markets, shopping malls, airports) all produce consistent high noise levels.  For more information on choosing the right hearing protection for you, check out one of these links!:

These are just a few of the many things we can do to protect our ears.  Remember, as audio professionals, our ears are our greatest asset, and we need to always remember to be our own advocate in protecting them.  If you’re at a restaurant or bar that has loud music playing, it’s ok to ask an employee or manager to turn it down.  We also have complete control over the electronics and tools we buy for our personal use.  Most have a noise rating listed, and this can help inform what kind of device you want to have around your precious little moneymakers.  We can’t stop the inevitable, but we can, and should, prolong it.  Long live the ears.

Audiologists and Hearing Tests

Hearing tests aren’t a common topic of conversation between audio professionals. But why? You’d think in an industry where our careers depend on hearing (and we do educate about hearing loss) we may want to get our ears checked periodically. A lot of us probably don’t do it because we think our hearing is fine. And tests are basic – most audiologists only test up to 8kHz which is fairly limited for audio engineers. But how many of us don’t get tested cause we’re scared? What if we actually have a hearing problem? Is it better to just not know?

I went to see Dr. Julie Glick of Musician’s Hearing Solutions after a couple of weeks of tinnitus and muffling in one ear that wasn’t going away (my first hearing test in 20 years). Her specialty is musicians and audio industry professionals and what caught my attention about her practice is that she does hearing tests up to 20kHz.

The hearing test process

Before she could conduct a hearing test, Dr. Glick had to clean my ears. She used a lighted “curette,” which looks like a clear crochet needle that lights up to see in the ear canal. The process was far from pleasant but necessary if you have bad wax buildup. The results were immediately noticeable. The muffling completely went away and while the tinnitus was still there, it was less noticeable against the noise floor of the room, which I couldn’t hear well before.

The hearing test was performed in an isolated booth in her office. The test itself is very simple: press a button when you hear a long beep. Each beep starts out at a noticeable level then drops a few dB until you can’t hear it anymore. Then, the beep changes to a different frequency. Dr. Glick does all the testing by computer so the button pushing is registered within the software to help correlate the results.

She also did a Tympanometry test, which checks how well the eardrum moves. A small probe is put in the ear and then the ears are given a puff of air. It’s easy and painless.

Test Results

We were immediately able to look at the results: My hearing was within normal range – but what is considered “normal” includes some loss. It’s sort of like acoustically tuning a room where a room could be called “flat” but its frequency response isn’t truly flat.

But there was a surprise when we looked at the Audiogram results: there was a noticeable difference between my ears. My right ear, the one I was concerned about, performed better than my left ear at high frequencies (8-12k). I knew immediately why: I played the violin for 15 years. I had a loud, high-frequency instrument inches away from my left ear for hours every day. I’ve probably had that discrepancy throughout my audio career.

Here’s a generic example of an audiogram to see what one looks like:

Sample Audiogram up to 8kHz

What do the results mean?

I asked Dr. Glick to help explain how any hearing loss (even if it’s considered within the “normal” range) would affect the work of an audio engineer or mixer. Frequencies like 12-16k are crucial for tasks like de-essing and noise reduction. I assumed a hearing curve is like an EQ curve (or a room curve) – that you have to compensate even when you’re mixing at nominal levels. But, that is actually incorrect.

The scale used to measure loudness outside the ear is dB SPL but hearing is on a scale of dB HL, or Hearing Level. The dB HL scale is based on the SPL scale but with a curve applied. The way Dr. Neil Bausman explains dB HL, “Our ears do not hear equally well at all frequencies. If our ears heard all frequencies of sound equally well, then we wouldn’t need the HL scale.” (His article is great for more detail!)

What the audiogram is showing is the level (HL) where the frequency completely disappears for you. This makes sense based on how a hearing test occurs because there is a threshold where a tone is played and you won’t hear it. So, if you’re mixing at a nominal level (like a reference level of 85 dB SPL) your hearing will always be “flat” – unless you have severe hearing damage at some frequencies. With normal to moderate hearing loss, it’s only when you drop to low-level mixing where you might not hear some of those frequencies. But, it doesn’t make sense to do detail EQ or de-essing work at a low level. It’s something to be aware of but doesn’t necessarily need to change how you work.
