Abstract
Abstract A computerized audiometer is provided with at least one head set, a control switch, a tone generator for providing a plurality of sequential tones of different frequencies and amplifications to at least one head set, and a central processing unit for receiving data representative of the response to the test of the person being tested as reflected by the operation of the control switch. The central processing unit is adapted to analyze the test data and produce a program representative of the correction required by the person being tested. The audiometer is provided with a programming output adapted for coupling to a hearing aid for programming a hearing aid by applying the program developed by the central processing unit to the hearing aid.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
136 words
A computerized audiometer comprising at least one head set; a control switch actuable by the person being tested and associated with each head set; tone generator means for applying a predetermined sequence of tones of varying frequency and amplification to said at least one head set for conducting an audiometric test; and a central processing unit coupled to said control switch for detecting the actuation thereof in coordination with the operation of the tone generator means, said central processing unit being adapted to process the outputs of said control switch and determine a program representative of the corrections required by the person being tested in terms of frequency band and amplification within each frequency band in a form suitable for programming a programmable hearing aid to conform to the correction required by the person being tested.
Claim 2
Dependent Claim
136 words
A computerized audiometer comprising at least one head set; a control switch actuable by the person being tested and associated with each head set; tone generator means for applying a predetermined sequence of tones of varying frequency and amplification to said at least one head set for conducting an audiometric test; and a central processing unit coupled to said control switch for detecting the actuation thereof in coordination with the operation of the tone generator means, said central processing unit being adapted to process the outputs of said control switch and determine a program representative of the corrections required by the person being tested in terms of frequency band and amplification within each frequency band in a form suitable for programming a programmable hearing aid to conform to the correction required by the person being tested.
