Defensive Listening 2

Bear screamHere are some more tips for things you can do to protect and preserve your hearing ability:

Scream. If you find yourself standing beside a firing jet engine or artillery piece without ear plugs, or any extremely loud sound source, voicing a twenty-second long, escalating scream may cause your strapedius muscle to tighten for a bit of extra protection.

Drive safely. If you wear earplugs to protect your hearing when you drive, just stay alert. Despite state laws against using headphones while driving, statistics show that deaf drivers are safer than the rest of us.

Avoid misuse of “personal electronics.” The abusive volumes sent through headphones and portable music systems caused high-frequency hearing loss among a third of the fad-prone new students at the University of Tennessee in 1981.

Set vanity aside. If you’re caught without earplugs when you need them to block noise — say, in a subway or at an airport — forget your self-consciousness and press your hands tightly to your ears. Save yourself!

At worst, double up. If you must attend or perform in a heavy metal rock concert, or face other extremely noisy environments, try wearing both earplugs and earmuffs.

Work soundly. If you work in an office, cut distractions and the destructive effects of noise: turn your desk to face the wall, and surface the wall with a sound absorbent material like carpet, fabric, or fiberglass insulation material. You’ll have to turn to face visitors, but you will do so without a barrier between you.

These screaming musicians may be heading for a serious loss of hearing due to damaged hair cells in their inner ear’s cochlea.

There are a number of steps you can take to protect and preserve your hearing. It’s important to put up a good hearing defense. Here’s just a few things you can do to protect yourself against an increasingly noisy world. 

Opera singer? Change jobs! Opera performers generate sound volumes in their heads which are as loud as jet engines heard at close range. As a result, they often suffer deafness as they age. If your job endangers your hearing, either wear ear protection, or quit. The same applies to sports or hobbies: gun lovers, don’t forget to wear ear plugs on the firing range! 

Put your ears on a low-noise diet. We recommend avoiding all sounds whose volumes exceed 80 decibels. Physiological stress measurably begins at this loudness level. Living with less noise can provide big health benefits, from less anxiety and lower blood pressure to improved immune response. 

Use earphylactics. Earplugs and “earmuff” noise-blocker headsets are a must for noise dieters. These devices can cut volume levels of ambient noise by up to 30 db. Don’t try cotton balls or tissue wads; they don’t stop much sound. There are several inexpensive types of earplugs. You’ll find one or more in most drug stores: disposable models in ear-canal-insertable plastic foam or a waxy “formable canal cover.” Industrial supply shops carry more expensive, washable pre-molded plastic or rubbery shapes – wild mushrooms, lawn lights, pagodas, etc.

Another option: connected pairs and singles. The cords on the back ends of the connected models make them easier to remove, and harder to lose. If you can, buy in quantity from a catalog house like Global Industrial (800-558-9966), where they have a wide selection and low unit prices—as low as 12 cents a pair. But wear whatever model you select for two hours before buying a large lot. The rough surfaces on some models can make them uncomfortable to wear for extended periods.

You can see even see a hearing specialist and have him make impressions of your ear canals; he’ll then be able to order custom plugs that will fit your ear canal perfectly, and that will pass the sounds you hear without frequency distortions.

If you don’t like wearing earplugs, or if you lose them too often, or if you need to be able to put your ear protectors on or take them off in a hurry, try sound-blocking ear muffs instead. These are the kind of protectors you see on the ground crew at airports. They offer between twenty and thirty decibels of sound attenuation, at prices ranging from ten to fifty dollars a unit.
