Around the World in Sound

Travel around the world in sound. Sound helps us to make sense of the world around us, and certain sounds can trigger memories. A recent survey by Amplifon, the worldwide dedicated hearing specialist found that two thirds of Brits say sounds evoke memories of places they have visited.

Teens warned over danger to hearing posed by rock concerts

Nearly three-quarters of teens attending a single rock concert experienced some form of hearing loss after the gig, according to the results of a new study.

 

Experts at the House Research Institute provided 29 teenagers with free tickets to a rock concert, measuring their hearing abilities before and after the three-hour show. The kids were seated at the front of the stage, around 15 rows from the floor.

During the 26-song set, sound levels ranged from 82-110 decibel A-weighting (dBA), with an average of 98.5 dBA. Ten of the 26 songs recorded levels above 100 dBA.

All teenagers were given advice on the importance of protecting the ears, but only three of the group chose to use the free earplugs provided, and the results showed the damage that exposure to loud noise can do. After the show, 53.6 per cent of teens reported slightly impaired hearing, yet the tests showed that 72 per cent of those who had taken part were now hearing less effectively. Furthermore, 25 per cent reported tinnitus (a ringing in the ears) which had not been there before the show.

Commenting on the results, M. Jennifer Derebery MD, lead author and physician at the House Research Institute, said: "Teenagers need to understand a single exposure to loud noise, either from a concert or personal listening device, can lead to hearing loss.

"With multiple exposures to noise over 85 decibels, the tiny hair cells may stop functioning and the hearing loss may be permanent."
