Volunteers needed for pioneering hearing study
12 July 2012
Researchers in Nottingham are recruiting 2,000 volunteers for a large-scale study which aims to find out if loud music really does wreck your hearing.
Experts at the National Institute for Health Research at the University of Nottingham say that surprisingly little research has actually been done into how sustained exposure to loud music affects our hearing in the long term, and that the results which are available are far from conclusive.
The new research project is the first to explicitly examine the effect of long-term exposure to loud music. Volunteers will carry out the 20-minute test online via the unit’s internet research portal. An anonymous questionnaire first collects data on hearing status, other factors that may have caused hearing damage and — most importantly — a lifelong history of music exposure in different environments, including gigs, pubs, clubs and using personal music players.
The volunteers then take a hearing test on their home computer, which measures the ability to hear a set of numbers against a background noise. Used together, the two sets of information allow the team to investigate the true long-term risk of music-induced hearing loss.
The researchers are particularly looking to attract those who work in quiet environments, to rule out some alternative factors in hearing loss. They are looking for the support of large companies to promote the study to their staff. Volunteers should be aged between 30 and 65 — old enough to have been exposed to more loud music than the average teenager, but young enough to be unaffected by age-related hearing loss.
PhD student Robert Mackinnon, who is carrying out the study, said: 'While we are frequently cautioned about the risks of loud music in popular culture and mainstream media, at present the threat remains exactly that — a risk. There simply isn’t enough scientific evidence at present to convincingly confirm or dismiss the danger of music-induced hearing loss.
'The only way we can assess the risk is to specifically gather evidence from an older generation of music listeners who have not just had a few exposures to loud music, but have potentially spent a lifetime exposing themselves to it.
'The results of this study will not just be used to help answer the question of if music exposure is damaging, but how much it is damaging. This will allow us to begin to better define safe listening limits — prevention is better than cure.'
