Abstract

The present invention relates to hearing aid training systems (100). More particularly, the present invention relates to the simulation of a hearing aid environment (108) prior to a user'"'"'s (105) purchase of a hearing aid. To create the simulated environment, the user'"'"'s hearing profile (111) is collected from all prior hearing tests. Prior hearing tests include information on all aspects of the user'"'"'s hearing, such as frequency and speech intelligibility. The software program (126) of this invention, and the audiologist using the software program (126), analyzes the user'"'"'s hearing profile and creates a simulation that demonstrates to the user how he or she would hear with a hearing aid. Furthermore, this invention provides a way to make additional adjustments to the hearing aid'"'"'s DSP data based upon user preferences prior to ordering the individual customized hearing aid.

means for creating a simulation to the user of the user'"'"'s hearing capability including a hearing aid.

2. The hearing device sound simulation system of claim 1, wherein the created simulation plays all the words and sentences that the user may interpret differently when wearing the hearing aid.

3. The hearing device sound simulation system of claim 2, wherein, through simulation, the user is able to test words and sentences with a hearing aid.

4. The hearing device sound simulation system of claim 3, further providing means for providing additional adjustments to the hearing aid'"'"'s DSP data based upon user preferences.
