Laser audiometer system |
摘要 |
An audiometer system for selectively generating audiologic test signals of selectable kind and intensity to be used in audiometric testing of the hearing abilities of persons. A repertoir of test signals and patterns is prestored in a source of test signals, each test signal having a corresponding unique address. Control means including a tablet or a display screen unit enable an operator to manually select desired test signals from said prestored repertoir. The operators selection causes said control means to address said source of test signals so as to reproduce the desired test signals. The source of test signals may be a digital disc player having a removable disc containing said repertoir prestored thereon as digital signal representations.
