Loud music damages your hearing — a warning that we're used to taking as fact. But surprisingly, 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 NIHR Nottingham Hearing Biomedical Research Unit, based at The University of Nottingham, 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 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 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, 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.
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 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."

Notes to editors: This study is funded by the National Institute for Health Research (NIHR).
The National Institute for Health Research (NIHR) is funded by the Department of Health to improve the health and wealth of the nation through research. Since its establishment in April 2006, the NIHR has transformed research in the NHS. It has increased the volume of applied health research for the benefit of patients and the public, driven faster translation of basic science discoveries into tangible benefits for patients and the economy, and developed and supported the people who conduct and contribute to applied health research. The NIHR plays a key role in the Government’s strategy for economic growth, attracting investment by the life-sciences industries through its world-class infrastructure for health research. Together, the NIHR people, programmes, centres of excellence and systems represent the most integrated health research system in the world. For further information, visit the NIHR website.
The University of Nottingham, described by The Sunday Times University Guide 2011 as ‘the embodiment of the modern international university’, has 42,000 students at award-winning campuses in the United Kingdom, China and Malaysia. It is also the most popular university in the UK by 2012 application numbers, and ‘the world’s greenest university’. It is ranked in the UK's Top 10 and the World's Top 75 universities by the Shanghai Jiao Tong (SJTU) and the QS World University Rankings.
More than 90 per cent of research at The University of Nottingham is of international quality, according to the most recent Research Assessment Exercise. The University aims to be recognised around the world for its signature contributions, especially in global food security, energy & sustainability, and health. The University won a Queen’s Anniversary Prize for Higher and Further Education in 2011, for its research into global food security.
