This report from the National Acoustic Laboratory at Australia’s Macquarie University found that 1 in 10 Australians used personal listening devices (PLDs) at dangerously high volumes.
Not surprisingly, those who reported using the devices at high volumes also reported more difficulty hearing things.
Only the abstract is available without a subscription, so I can’t comment on details of the study, which would be stronger if actual hearing tests had been done on the subjects, but the final line of the abstract is one that I agree with entirely:
Although PLD use alone is not placing the majority of users at risk, it may be increasing the likelihood that individuals’ cumulative noise exposure will exceed safe levels.
And that’s the problem with studies focusing just on personal listening device use. They are only one small part of the total daily noise dose. Flamme, et al., found that 70% of adults in Kalamazoo County, Michigan received total daily noise doses exceeding the Environmental Protection Agency’s safe noise limit of 70 decibels time weighted average for a day. That’s why the Centers for Disease Control (CDC) recently reported that almost 25% of American adults had noise-induced hearing loss, many if not most without occupational exposure.
As the CDC states, noise-induced hearing loss is preventable. No noise, no hearing loss.
Protect your ears now and you won’t need hearing aids later.
