1. A system for compensating for hearing impairment comprising:
- an electronic device for producing sound in response to an electrical signal; and
a hearing aid device for compensating for a uses'"'"'s hearing impairment profile including a processor and a first and a second removable and replaceable storage means, said hearing aid device electrically connected to said electronic device and intercepting the electrical signal, said processor transforming the electrical signal according to the hearing impairment profile and passing the transformed electrical signal to the electronic device, said first removable and replaceable storage means storing a first function according to which said electrical signal is transformed and said second removable and replaceable storage means storing a second function according to which said electrical signal is transformed, wherein one of said storage means is implemented in a first handset earpiece that physically replaces a second handset earpiece on a telephone handset, said first handset earpiece during use being held next to a caller'"'"'s face by said telephone handset.

Abstract
A system integrates a hearing aid with devices such as wireless telephones, advantageously avoiding radio frequency (RF) interference. In one embodiment, a processor transforms an electrical signal to compensate for a hearing impairment. The function used for signal transformation can be accessed via a processor memory enhancement such as a smart card. A digital-to-analog converter (DAC) converts the transformed signal to an analog signal, which then goes to an amplifier and speaker. In other embodiments, an analog amplifier transforms the electrical signal.

2. A wireless telephone system comprising:
-
a wireless telephone receiver that receives and transmits an electrical signal;
a hearing aid device including a processor, said hearing aid device electrically connected to said receiver and receiving said electrical signal from said receiver, said processor receiving and transforming said electrical signal according to a hearing impairment profile, the hearing impairment profile being pre-stored on a removable and replaceable memory coupled to the hearing aid device, whereby the memory is interchangeable by a user for selecting an alternative hearing impairment profile for use by a different user or for use in a different environment; and
a speaker located in a wireless telephone in said system, said speaker outputting said transformed signal as sound;
wherein said removable and replaceable memory is implemented within a first handset earpiece that physically replaces a second handset earpiece in said wireless telephone. - View Dependent Claims (17, 18, 19)
