Members of a number of different scientific disciplines and professional groups are active in audiology, which deals with the investigtion of hearing and hearing disorders and all related phenomena, as well as the diagnosis and treatment of hearing impairment and the rehabilitation of hearing-impaired and deaf patients. The spectrum ranges from medicine (especially ear, nose and throat medicine; phoniatrics and pediatric audiology; and occupational medicine), the natural sciences and humanities (physics, biology, and psychology), engineering sciences, pedagogy for the hearing-impaired up to audiology and medical/technical assistance occupations. Founded in Münster, Westphalia in 1996, the German Society of Audiology (DGA) has set itself the goal of combining these different professional groups into a scientific organization to meet the needs of audiology and to support it in research, development, education and clinical practice in Germany and Europe. The multidisciplinary nature of the Society is also evident in the composition of the board. The DGA is a member of the European Federation of Audiological Societies (EFAS), founded in 1992, and actively participates in European cooperation.
