title: Proem to a quantum leap in audiometric data collection and management.
abstract: A revolution began in 1961 when Weiss first mated a minicomputer to an audiometer. Today's technology offers a number of aids to the audiometrist in standardizing stimulus presentation patterns, objectifying and validating responses, computing HTL from a response pattern, computing significant threshold shifts from baseline audiograms, computing percentage binaural hearing impairment for a person, etc. Audiometers can be made which self-calibrate and are fail-safe. Furthermore, a revolution has occurred in replacing an audiogram written record, for example a card, with a system in which the audiometer transfers HTL data directly into computer storage without the possibility of transcription error. A group of turnkey and interlocking terminals allows the audiometric data of any individual serviced to be retrieved and/or updated from any terminal in the system. This paper lists commercial models simulating standard manual audiometry, models computerizing Bekesy audiometry, and some experimental models on yet other principles. Psychometric methods and methods for response validation suitable for audiometry are discussed, and out of many possible suggestions a few are offered for audiometric paradigms which may go beyond simulation of ASHA guidelines and ANSI specifications for manual threshold audiometry in order to take advantage of the power available from the computer as a tool in audiometry. For example, a computer can scan the responses of as many as 32 subjects simultaneously, offer each an adaptive program based on his response, and printout HTL's in conventional audiometric format.
