Abstract

A sound filter system to simulate any individual hearing loss up to 120dB at any of the following centre frequencies: 125, 250, 500, 750, 1000, 1500, 2000, 3000, 4000, 6000 and 8000 Hertz. Each frequency filter is calibrated in intensity units of 5dB from 0dB (no filter) to -120dB, giving twentyfour intensity variations per frequency. The Hearing Loss Simulator has sockets for audio input and for headphones and tape-recorder to monitor and record the effects of any simulated hearing losses. The effect of any hearing aid on the hearing loss may be assessed by passing the hearing aid output through the Hearing Loss Simulator and monitoring the results via the headphones or tape-recorder. The recorded outputs may be compared so that the most suitable aid for the hearing loss may be selected.

Description

SPECIFICATION Hearing loss simulator A sound filter system for the following frequencies: 125, 250, 500, 750, 1000, 1500, 2000, 3000, 4000, 6000 and 8000 Hertz.
Each frequency filter is calibrated in intensity units of 5 dB from 0 dB (no filter) to dB, giving twentyfour intensity variations for each frequency. This range of frequencies and intensities is for the purpose of simulating any hearing loss of not more than 120 dBs at any of the above-mentioned frequencies (the hearing loss having been previously determined by audiometric procedures).
The Hearing Loss Simulator is provided with input sockets for microphone, tape-recorder and record-player, and with output sockets for a loudspeaker and tape-recorder input lead. Thus, the effect of the simulated hearing loss on any sounds passed through the Hearing Loss Simulator may be recorded on a tape-recorder.
The benefit of any hearing aid to the person whose hearing loss has been simulated may be assessed by passing sounds through the hearing loss simulator with output via the loudspeaker, through the hearing aid via the hearing aid microphone; the resulting output from the hearing aid may then be recorded on a tape-recorder via the tape-recorder microphone. Any hearing aid outputs thus recorded may then be compared by listening to the tape-recordings so that the most suitable aid for the person whose hearing loss has been simulated may be selected.
(Alternatively, the output of sound from the hearing aid may be passed through the Hearing Loss Simulator and recorded by the tape-recorder to assess the effects of the simulated hearing loss on sound amplified by the hearing aid).
Claims
A sound filter system to simulate any individual hearing loss up to 120 dB at any of the following centre frequencies: 125, 250, 500, 750, 1000, 1500, 2000, 3000,4000, 6000 and 8000 Hertz.
(The hearing loss having been previously determined by audiometric procedures).
Each frequency filter is calibrated in intensity units of 5 dB from 0 dB (no filter) to -120 dB, giving twentyfour intensity variations for each frequency.
The Hearing Loss Simulator is provided with audio input sockets and with output sockets for headphones and tape-recorder. Thus, the effect of any simulated hearing loss on any sounds passed through the Hearing Loss Simulator may be monitored via the headphones or recorded on a tape-recorder.
The effect any hearing aid may have on any hearing loss may be assessed by passing sounds through the hearing aid with the consequent output passed through the Hearing Loss Simulator to be monitored via the headphones or recorded on the tape-recorder. Any hearing aid outputs thus recorded may then be compared so that the most suitable aid for the person whose hearing loss has been simulated may be selected.
