Question: I'm worried about my hearing because I played in a rock band when I was a kid. How dangerous is the sound level on the bandstand?
Answer: Sound volume is measured in decibels (dB). You risk hearing loss when you are exposed to sounds at 85 decibels or more. The louder the sound and the longer the exposure, the greater the risk.
Here's the bad news: rock music is on many lists as an example of a dangerous sound. Here's one of those lists:
30 dB = library
50 dB = rain
60 dB = conversation (apolitical)
70 dB = vacuum cleaner
80 dB = busy street
90 dB = shop tools
100 dB = chain saw
110 dB = rock music among audience
120 dB = rock music on bandstand
130 dB = jackhammer
140 dB = air raid siren
150 dB = rock music crescendo
If I played electric guitar in the 1960s next to one of those gigundo amplifiers, I’d get to a doctor for an ear exam.
But you don't have to be a rocker to suffer from noise-induced hearing loss (NIHL); anyone at any age can be a victim. About 10 percent of Americans between ages 20 and 69 already may have suffered permanent damage to their hearing from excessive noise.
You can sustain NIHL at work, play or sitting around the house. Music players turned up too high can damage your ears. Woodworking can be an unsafe hobby. Leaf-blowers reach hazardous sound levels.
Most people's hearing diminishes with age. About 1 in 3 Americans over age 60 suffers from some loss of hearing, which can range from the inability to hear certain voices to deafness. Those who are healthy and not exposed to loud noise can maintain their hearing for many years.
The first symptom of NIHL is the inability to pick up high-pitched sounds, or not understanding conversation in a crowd. As hearing declines, you lose the lower-pitched sounds.
Prevention is the key to NIHL. Here is some advice to avoid damage to your ears:
