Abstract: A system for establishing a communication to communicate with a hearing health professional, providing data related to hearing aid settings to the hearing health professional, receiving a hearing aid profile in response to providing the data, and providing the hearing aid profile to a hearing aid through a second communication link.

Abstract: A hearing aid includes a microphone to convert audible sounds into sound-related electrical signals and a memory configured to store a plurality of hearing aid profiles. Each hearing aid profile has an associated audio label. The hearing aid further includes a processor coupled to the microphone and to the memory and configured to select one of the plurality of hearing aid profiles. The processor applies the one of the plurality of hearing aid profiles to the sound-related electrical signals to produce a shaped output signal to compensate for a hearing impairment of a user. The processor is configured to insert the associated audio label into the shaped output signal. The hearing aid also includes a speaker coupled to the processor and configured to convert the shaped output signal into an audible sound.

Abstract: A media player includes a processor configured to receive media content from a content source and to process the media content produce an audio signal. The media player further includes a transmitter coupled to the processor and configured to transmit the audio signal to a hearing aid through a communication channel.

Abstract: An electrocardiogram enhancement system and apparatus is provided. Small amplitude, high frequency notches associated with myocardial disease and arrhythmias can be recorded by conventional chart recorders. In addition, the notches are clearly visible in the recorded waveform for visual detection and analysis of the notches by medical personnel.In the system of the present invention electrocardiogram signals having small amplitude, high frequency notches are enhanced; first, by selectively amplifying the notches while keeping the amplitude of the remainder of the waveform constant and, second, by uniformly expanding the signal in the time domain wherein the inter-component frequency and inter-component phase relationships are maintained.

Abstract: A microprocessor based sound enhancement system in which frequencies outside of the auditory range of the human ear are translated into sound within the auditory range by translating each frequency component of the entire frequency spectrum of the input signal by a time scale compression factor. Preferably, a microprocessor transforms an electrical signal corresponding to the input signal into a frequency spectrum signal comprising frequency components having frequency, phase, and amplitude elements by performing a fast Fourier transform (FFT) operation on the input signal. The frequency components of this transformed signal are translated and the resulting translated frequency spectrum signal is transformed into a time varying output signal by performing an inverse FFT operation on the translated frequency spectrum signal. When heart pulses or similar periodic waveforms are monitored, the pulse rate of the signal is maintained in the output signal.
