Provided is a method of automatically fitting a hearing aid. The method includes the steps of entering an audiogram of a test subject, defining criterion gains and SSPLs according to the test subject's audiogram in each test frequency band, generating 70dB SPL long term speech spectrum noise, and measuring the gains and SSPLs of the amplified sound in front of test subject's eardrum using the probe tube microphone, comparing the measured gains and SSPLs with the criterion gains and SSPLs and if the measured gains and SSPLs are less than the criterion gains and SSPLs, increasing the gain and SSPL of the hearing aid and repeating measurement, and if the measured gains and SSPLs becomes equal to the criterion gains and SSPLs, setting the gains and SSPLs of the hearing aid at that time as an actual gain and/or SSPL of the hearing aid and saving the automatic fitting device.

A low-cost, programmable, time-limited hearing aid (104) and a means (102) to program the hearing aid with user-specific hearing-loss data (101) for the purpose of emulating the performance of a more permanent, but more costly, hearing aid device. The hearing aid is operational for only a limited time, and is intended for temporary, evaluative purposes. By providing the user with a low-cost, but temporary, means to evaluate the benefits of assisted hearing, he or she becomes more comfortable with its use, and therefore is more amenable to the more involved process and greater expense of being fitted for a more permanent hearing health solution. A method of use of the hearing health aid and the associated programming system that allows a hearing-loss candidate to evaluate the effectiveness of the hearing aid device is also presented.
