Researchers at the University of Nottingham are looking for volunteers for the first study to explicitly examine the effect of long-term exposure to loud music, and the hearing damage it causes.

A new research project at the National Institute for Health Research (NIHR) National Biomedical Research Unit in Hearing, 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. It may seem obvious to the pro-audio world, but a recent Action on Hearing Loss survey in the UK suggests the wider public may not be as aware of the damage loud music can cause, and surprisingly little research has actually been done into how sustained exposure to loud music affects our hearing in the long term. The results we do have are far from conclusive. For this study, 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.” Dr .Ralph Holme, Action on Hearing Loss’s head of biomedical research added: “We welcome any study into the link between loud music and hearing loss, an issue we’ve been campaigning on for over ten years. We encourage music lovers who regularly go to clubs and gigs to wear earplugs and take seriously the dangers of listening to their mp3 players for too long and too loud. We also know from our work with musicians and clubbers that, for some people who haven’t taken seriously the dangers of loud music, they’ve suffered from premature hearing loss or tinnitus.” For more information on the study, or on promoting the research to your staff, contact Robert Mackinnon at the NIHR National Biomedical Research Unit in Hearing by email at msxrm1@nottingham.ac.uk or by calling 0115 823 2600. www.nihr.ac.ukwww.actiononhearingloss.org.uk



Live Music Act in effect

The Live Music Act took effect 1 October and to coincide with the launch, the Musicians’ Union has created a ‘Live Music Kit’ containing practical and creative advice for venues wishing to host live music events.


Loudness or level?

In this week's feature the Prof looks at normalising and maximising, and how 'loudness wars' are having a negative effect on reproduced sound


Loudness discussions turn to radio and music

Loudness has dominated audio for television discussions over the last two years but now attention is beginning to shift to radio and music recording. These areas will be discussed at the Loudness Summit at the Royal Institute of British Architects (RIBA) in central London on Friday.


Standardising loudness

For years there was no official standard to combat the problem of broadcast loudness. Now there are several and while, as Kevin Hilton reports, they are all similar in technology and intent, there are enough differences to cause uncertainty.
