ABSTRACT A programmable patient controlled master hearing' aid is disclosed which consists of a hearing aid test module 200, an operator's console 50 and a patient's console 45, both of which are microprocessor 59,77 based, and all of which are interconnected to provide a testing apparatus which is used by the patient to select electronic components to be employed in a hearing aid. The testing device has selectable electronic components 110, 210, 212, C2, R1, R2, R3 that match the components which will be used in the hearing aid which the patient selects as best assisting or addressing the patient's hearing loss. The patient is located in the center of a sound field created by multi- ple speakers 22 which accurately reproduce both pre-recorded environmental background sounds and pre-recorded or live "target-stimuli" such as speech. Thus surrounded by a simulation of real-world listening situations, the patient initially selects a hearing aid shell assembly 12 which comfortably fits in the patient's ear. A test module 200 which is connected to the patient's console 45 is then employed which snaps into the hearing aid shell assembly 12 and provides decision tree choices (Fig. 10) of electronic components (Fig. 6) and concomitant sound qualities which the patient chooses by listening to various combinations of components and sound conditions. The patient chooses those components which give the most acceptable amplification and performance characteristics, which best address the patient's hearing loss. Similarly, tinnitus conditions can be addressed as well. After the patient has completed the test procedure and selected those components which best address the patient's hearing condition, electronic components 60, 112, 210, 212, 220, B1, C1-C4, R1-R3 with the same specifi- cations as those used during testing are snapped into the earshell assembly 12 used during the test so that the patient can leave with the hearing aid that he or she has selected.
