HEADSET STEREOS

Most headset stereos have one thing in

common: they can cause hearing loss.

Studies have shown that sound levels from the

machines can reach 115 decibels or more - roughly

equivalent to standing 100 feet from a commercial jet at the moment of take-off. At

that level, permanent hearing damage can occur after just 15 minutes. And the

earlier a child begins using a headset, the more damage can accumulate. Loud

noise causes hearing loss by killing irreplaceable hair cells in the inner ear. Normally,

the process occurs slowly as people age, but noise damage can accelerate it.

Noise-induced hearing loss is insidious; damage may not be apparent until later

in life. Since headsets are used privately, parents often don't realize how loud their

children's music is.

EXERCISE 1: Find words or phrases in the passage which mean the same as:

C) caused by commercial jets is irreparable

D) is more damaging for the ear than anything else

E) can be dangerous if the person is standing 100 feet from the source of sound

2. The normal process of hearing loss

A) can start at any age, depending upon the condition of the person's ears

B) can be sped up by the harm done by loud noise

C) occurs if the person is frequently subjected to loud noise

D) is noticed only when irreplaceable hair cells in the inner ear have been killed

E) is caused when sound levels from machines reach 115 decibels or more

3. Unable to hear the music their child is listening to through a headset, parents
