Music and audiometric asymmetries

Marshall Chasin
I always am amazed by how much the study of music and musicians teaches me about basic audiology.  One of the first things we learn in our first course on noise and its control in school is that the audiogram for noise exposure should be symmetrical.  Asymmetries in the audiogram are most likely related to non-noise etiologies such as the
