Langtext This is the report of the Inter-Society Working Group on Hearing Disability, which was founded in 1986 and completed its work in 1991. The report proposes a method for the quantification of hearing disability resulting from hearing impairment for the purposes of description and compensation, with particular reference to noise-induced hearing deficit. The book will be of interest to medical specialists concerned with the assessment of hearing disability as well as to legal professionals dealing with compensation claims in this area and to those with an academic interest in disability assessment.
