Early signs of hearing damage seen in young concert goers

This report in The Conversation, a UK website, discusses research showing that young adults who regularly attend loud clubs and rock concerts have evidence of hearing loss. The hearing loss found falls into the “hidden hearing loss” category, so-called because it is not detected by standard hearing tests (“pure tone audiometry”), but only by techniques currently used only in research. These tests found subtle hearing loss and decreases in auditory signals sent to the brain. There were equal amounts of damage in musicians and non-musicians alike. It looks like all the young adults had too much noise exposure.

Hidden hearing loss is now thought to be the cause of the “speech in noise” problem, where middle-aged and older adults have difficulty following one conversation among many in a noisy environment. That’s a complex task for the ear and the brain, requiring lots of auditory information to be processed centrally. When the ear and brain are damaged, that doesn’t happen.

The only quibble I have with The Conversation’s report is that the authors make the common mistake of citing occupational noise exposure levels when talking about noise exposure in the public. Occupational noise exposure limits don’t protect workers from noise-induced hearing loss, and the UK’s 85 decibel exposure limit cited is certainly not safe for hearing.

The only noise exposure level that prevents hearing loss is a daily average of 70 decibels, which is much less noise than most urban dwellers around the world get every day.

Prevention of noise-induced hearing loss–hidden or not–is simple: avoid loud noise exposure and use hearing protection if you can’t.

Experts: Hearing loss is on the rise among young adults

and their personal audio devices may be at least partially to blame. Melanie Campbell, a professor of Rehabilitation Medicine at the University of Alberta, warns that young adults “may be destined to swap out their headphones for hearing aids.” The problem is that this cohort “particularly loves music, they love it loud and they have very few worries about the future.” Campbell notes that World Health Organization statistics show that “[m]ore than one billion young adults are at risk of hearing loss,” and “[a]mong people aged 12-35 years, almost half are exposed to dangerously high levels of noise from personal audio devices like headphones while four out of 10 are exposed to unsafe levels of sound at concerts and other entertainment venues.”

According to Campbell, the primary cause for this hearing loss these days is noise-induced hearing loss (NIHL). What makes hearing loss particularly insidious, is that people generally don’t lose their hearing overnight. Instead, says Campbell, “[i]t creeps up and you gradually forget that you’re not hearing the door squeak, or you don’t hear people’s heels on the floor.”

To give young Canadians the information they need to protect their hearing and prevent hearing loss, Campbell has been promoting Sound Sense, a project led by the Hearing Foundation of Canada that spreads awareness about hearing loss in Canadian schools.

Spreading awareness about NIHL and how to prevent it is, of course, the the best option. Every school in the U.S. should regularly test students’ hearing and include information about NIHL in their health education programs. Given that NIHL is 100% preventable, the failure to educate children about how they can avoid NIHL is as insidious as the disorder.


Age doesn’t matter,

you could have hidden hearing loss (and not know it). WMAR Baltimore reports on hidden hearing loss, a relatively recently discovered hearing breakthrough that explains how people who pass hearing tests have problems hearing in noisy environments.  WMAR interviewed audiologists about this breakthrough, who said that “why patients can’t decipher speech in noisy situations has been unexplained, but a new breakthrough is changing that.”  The researchers who made the hidden hearing loss breakthrough studied young adults who were regularly overexposed to loud sounds, and found that “hidden hearing loss is associated with a deep disorder in the auditory system.”

It’s never too late to protect the hearing you have.  Exposure to loud sounds damages hearing.  Period.
