How can you tell if you or someone near you has a hearing loss?
Turning up the television or radio is a very common sign of a hearing loss. The
appropriate volume may seem too loud to others.
Focusing on one speaker in a crowded or noisy environment is often especially difficult
for a person with a hearing loss.
In a car, the engine, road or wind noise can make it hard to hear a conversation, the
radio or important traffic sounds.
People with a hearing loss frequently feel that others mumble or need to repeat what
theyve said. Often, a person will hear, but not understand, whats being said.
Social occasions are often difficult for a person with hearing loss. Background noise,
such as music or group conversations, can become overwhelming, making it impossible to
participate in a conversation.
Its easy to forget how much we rely on our hearing every day. Sirens, automobile
horns, and other people are only a few of the things that we need to be able to hear
In church, theaters, and auditoriums, it can be very difficult to hear a speakers
voice. Many facilities have assistive listening devices available for those with hearing
loss. To put the chart on the right into perspective, according to OSHA's regulation of
industrial noise exposure, an average worker surrounded by levels around 85-90dB for an
eight hour day will not exceed the limits of exposure time within a 24 hour period of
time. However, when the sound levels exceed 100dB, your exposure time is reduced to
two hours. When sound levels exceed 115dB, your exposure time is drastically reduced to 15
minutes. This puts riding a motorcycle or playing a loud
guitar in a whole other realm as 103dB is comparable to a running chainsaw or contrete
Cupping your hand behind your ear can help a little, but its no substitute for a
properly fitted hearing aid. And remember - a hearing loss is more noticeable than a
hearing aid! Protect your hearing by getting annual hearing tests. Although there are
several versions of hearing protection devices on the market, a custom set of earmolds is
still the best answer in suppressing sound. They provide excellent attenuation values and
are comfortable to wear for extended periods of time. They can even be molded with
high-grade transducers, which allow for stereo compatibility or communications. To find
