  • Patent number: 5928160
    Abstract: A home hearing test for use with a conventional home audio system comprising an audio player and a set of headphones connected to the audio player. The home hearing test includes an audio medium such as a compact disc playable in the audio player and containing a calibration tone recorded at a predetermined decibel level and a number of prerecorded sequences of tones. Each sequence has tones recorded at different decibel levels and decreasing by a step value. In a first sequence for obtaining a rough estimation of hearing threshold level, the tones start at 70 dB HL and decrease by 10 dB steps to 0 dB HL. In secondary sequences, tones start and end with tones from the first sequence and decrease in 2 dB steps. The home hearing system includes a calibration device for calibrating the output of the audio system to the ears of a person wearing the headphones against the predetermined decibel level of the calibration tone.
