Information on Hearing Damage

Understanding Noise Induced Hearing Loss
Exposure to loud sounds can damage your hearing, causing hearing loss and tinnitus (ringing or buzzing in the
ears). While a variety of things can lead to hearing loss, including aging and side effects of certain medications, the
most common cause of non-age-related hearing damage is loud noise. Extremely loud sounds, such as gun shots
or firecrackers at close range, can cause immediate hearing damage. Hearing damage can also occur over time
due to repeated exposure to loud sounds such as industrial noise or loud music. With continued exposure to loud
noises, ears may become accustomed to the sound level, which may result in permanent damage to hearing
without any noticeable discomfort.
Temporary and permanent hearing loss
Noise induced hearing loss and tinnitus may be temporary or permanent.
Ears typically recover from temporary hearing damage in a short time.
However, ears may not recover completely, and some damage may be permanent. Repeated exposure to loud
sound can cause more and more damage, and eventually lead to serious hearing problems. Scientists generally
agree that, over time, exposure to harmful levels of noise can lead to permanent noise-induced hearing loss by
damaging and/or destroying the inner ear's sensory hair cells.
Loud sounds + time = hearing loss
The more time you spend exposed to loud sounds, the more likely you are to damage your hearing. All of the loud
sounds that you are exposed to during a day add up - continued exposure to loud sounds can prevent your ears
from recovering and also cause additional damage.
Symptoms of Hearing Loss
While not all noise-induced hearing loss is noticeable, symptoms may include a sensation of pressure or fullness in
your ears, ringing in your ears, or muffled speech. If you experience these symptoms or believe you may have
experienced noise induced hearing loss, you should have your hearing checked by an ear doctor or audiologist.

WARNING
032374o
The cradle connector on the CA10 contains a magnet. To avoid potential of magnetic
interference with the function of the pacemaker, do not wear the CA10 on your shirt.
The CA10 radio generates magnetic energy. Pacemaker manufacturers recommend that a
minimum of 15 cm (6 inches) be maintained between a handheld wireless device and a
pacemaker to avoid potential interference with the pacemaker.
