Abstract:
:A large number of personal amplifiers have recently become available commercially. These devices have not been classified as hearing aids by the FDA and are therefore not subject to the FDA rules and regulations governing the sales of hearing aid devices. In this investigation, several of these personal amplifiers were evaluated to determine potential benefits and problems for each device. The devices were evaluated electroacoustically and, also, subjectively by a group of adults with sensorineural hearing loss. The results of the electroacoustic evaluation revealed very sharply peaked frequency responses. The subjective evaluations revealed tremendous variability, with some preferences for power and low-frequency amplification. Clinical implications of these results and suggestions for further research are provided.
