Loud music damages your hearing ­— a warning that we’re used to taking as fact. But little research has actually been done into how sustained exposure to loud music affects our hearing in the long term, and the results we do have are far from conclusive. A new research project taking place at the National Institute for Health Research (NIHR) National Biomedical Research Unit in Hearing, based at the University, is the first to explicitly examine the effect of long-term exposure to loud music. Researchers are looking to recruit 2,000 volunteers from an ‘older generation of music listeners’ in a large-scale study that is the first of its kind in the world. Volunteers carry out a 20-minute online test after completing an anonymous questionnaire on hearing status, other factors that may have caused damage and — most importantly — a life-long 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. Used together, the information allows the team to investigate the true long-term risk of music-induced hearing loss. Researchers are particularly looking to attract those who work in quiet environments, to rule out some alternative factors in hearing loss. They are hoping large companies will 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 is carrying out the study. “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.” For further details, contact Robert at: msxrm1@nottingham.ac.uk or call 0115 823 2600.
