Hearing loss in musicians - Is there a problem?

There are several unique reasons to be concerned about sound exposure and its effect on musicians’ hearing. First of all, musicians’ working hours are usually quite varied as compared to most employees, especially during performance weeks. Also, musicians spend a varied amount of time practicing, playing solo and as a member of different groups, and enjoying the music of others. One review article suggested that classical musicians play an average of 25 hours per week (Palin 1994), but this could vary widely from week to week, and from person to person.


Most people are aware that loud noises are bad for your ears, and might lead to hearing problems down the road. Since listening to music is a positive, pleasant, and desirable activity for many people, it may come as a surprise that music can have a negative effect on hearing too.

Work-related hearing loss is quite a different problem for those in the music industry than it is for industrial workers. Musicians and DJs regard themselves as having superior hearing, specially trained to detect nuance or tone, and consider that their hearing is their livelihood (Axelsson and Lindgren 1981; Early and Horstman 1996). A slight hearing loss that may not bother an industrial worker may cause difficulties for a musician. In addition, controlling musicians’ exposures poses a different challenge than it does for other types of employees.

Even though sound levels can be exceedingly high at music venues, very few investigations on the hearing of musicians had actually taken place as of the early 1980’s (Axelsson and Lindgren 1981). An early study on the hearing of orchestral musicians at an opera house found that 42% of participants had hearing loss that was greater than expected for their age (Axelsson and Lindgren 1981). Many other studies, including both classical and pop musicians, have found similar results: musicians have worse hearing than would be expected based on their age (Lebo and Oliphant 1968; Westmore and Eversden 1981; Jansson and Karlsson 1983; Hart, Geltman et al. 1987; Ostri, Eller et al. 1989; Royster, Royster et al. 1991; Fearn 1993; Jaroszewski and Rakowski 1994; Jaroszewski, Fidecki et al. 1998; Eaton and Gillis 2002; Kahari, Zachau et al. 2003).
Other researchers report no difference between musicians and other workers (Arnold and Miskolczy-Fodor 1960; Karlsson, Lundquist et al. 1983; Johnson, Sherman et al. 1985; McBride 1992; Kahari 2001); this difference in finding may be due to varying definitions of what constitutes hearing loss, difficulties in quantifying leisure noise exposure, or poor study quality (Sataloff 1991).

The general consensus in the literature suggests that hearing loss is a problem for musicians, and this varies across type of music played (i.e. – rock or jazz or classical),and type of instrument played (Palin 1994; Mikl 1995). It has been suggested that since sound pressure levels (SPL) produced by music can be (and often are) well above the recommended 85 dB, we have good reason to be concerned about musicians’ hearing.

Another complaint from some musicians (but more typically of industrial workers) is a disease called “tinnitus”, which is a permanent ringing in the ears caused by chronic exposure to loud noises (Axelsson and Ringdahl 1989; Axelsson and Prasher 2000; Lockwood, Salvi et al. 2001). More research needs to be done on the musician’s experience with this often highly debilitating disease.
