Music as noise

Project Details


Music is an important part of society, it is one of the most common social and cultural expression forms and it has been a part of human evolution since prehistoric times. Today music can be found at many levels of society and it has a prominent role for an ever increasing number of people, both musicians and music consumers. This dominant role of music in society has led to its mass distribution as recorded and live music. The technological advances in electro-acoustics, recording and storage systems, has made it possible for sound systems to produce high intensity sounds with little distortion, at levels that are comparable to industrial noise. There is no question that intense sound exposures have detrimental effects on hearing. This is based on decades of experience with noise exposure in the work environment. But, how much of this experience is directly applicable to music sound exposure? And what regulations and guidelines are necessary to prevent unnecessary risk of hearing damage from music sound exposure? These questions cannot be addressed properly until more is known about how intense music sound exposure affects hearing. The aim of this project is to investigate effects on hearing produced by music sound exposure and to compare them to sound exposure from industrial noise. The problem is approached by measuring changes in human Oto-Acoustic Emissions (OAE) induced by music (live concerts, recorded music, etc.) and comparing the effects to changes produced by industrial noise of similar characteristics.
