Abstract: A binaural hearing aid system for a user is set forth. The system includes a casing adapted and constructed to encase a hearing aid system suitable for wearing below the neck of the user. A first digital signal processor, having an audio input from a first microphone of the hearing system, is also provided. The first digital signal processor produces a first audio output corresponding to a first hearing profile. A second digital signal processor having the audio input from the second microphone of the hearing system is also provided. The second digital signal processor produces a second audio output corresponding to a second hearing profile.

Abstract: A personal listening device in a handheld form factor includes an input port for receiving an audio signal, a processor for selecting equalizer settings responsive to a selected hearing profile, an equalizer for equalizing the audio signal according to the equalizer settings, and an output port for outputting the equalized audio signal to a speaker, headphone, or other audio output device. The personal listening device also includes a tone generator and user input device coupled to the processor, configured to administer a sequence of tones, generate audio instructions, and receive user input, thereby administering a hearing test and generating a user hearing profile. The device may be operated to administer multiple tests and store multiple hearing profiles, and to provide hearing profiles to other devices.
