摘要： A hearing aid which is operable in an audiometric testing mode includes an audio output section, a volume control, a switching device, and a processor. The audio output section sequentially generates a number of testing sounds at a corresponding number of testing frequencies and provides each testing sound to the person who will be using the hearing aid. The volume control is used to adjust the amplitude of each testing sound to a level of audibility just above the person's threshold of hearing at the corresponding testing frequency. When the appropriate threshold volume level is set, the switching device is operated to generate a control signal. Based on operation of the volume control and the switching device for each of the testing sounds at each of the testing frequencies, the processor sets a plurality of threshold hearing levels associated with the corresponding testing frequencies. The threshold hearing levels collectively define an amplitude-versus-frequency profile which the processor applies in processing digital audio signals during normal use of the hearing aid.

摘要： A digital hearing aid is provided that includes front and rear microphones, a sound processor, and a speaker. Embodiments of the digital hearing aid include an occlusion subsystem, and a directional processor and headroom expander. The front microphone receives a front microphone acoustical signal and generates a front microphone analog signal. The rear microphone receives a rear microphone acoustical signal and generates a rear microphone analog signal. The front and rear microphone analog signals are converted into the digital domain, and at least the front microphone signal is coupled to the sound processor. The sound processor selectively modifies the signal characteristics and generates a processed signal. The processed signal is coupled to the speaker which converts the signal to an acoustical hearing aid output signal that is directed into the ear canal of the digital hearing aid user. The occlusion sub-system compensates for the amplification of the digital hearing aid user's own voice within the ear canal. The directional processor and headroom expander optimizes the gain applied to the acoustical signals received by the digital hearing aid and combine the amplified signals into a directionally-sensitive response.

摘要： A hearing instrument includes a main housing, an in-the-ear-canal sound receiving unit, and a sound emitting unit. The sound emitting unit may be located completely in the ear canal or may be linked to the ear canal by an acoustical tube. An acoustic blocker separates the sound emitting unit and sound receiving unit. The main housing is configured to be located outside of the ear canal and includes processing circuitry that is operable to process signals. The acoustic blocker is configured to at least substantially occlude the ear canal and acoustically isolate the sound emitting unit from the sound receiving unit.

摘要： A digital quasi-RMS detector is provided that approximates the time-varying RMS energy of a signal. The digital quasi-RMS detector rectifies the signal and compares the rectified signal with an estimated present energy value of the audio signal. If the difference between the rectified signal and the estimated present energy value is not greater than zero, then the digital quasi-RMS detector multiplies the rectified signal by a first time constant to generate a first filtered signal and sums the first filtered signal with the estimated present energy value to determine the approximate RMS energy. If the difference between the rectified signal and the estimated present energy is greater than zero, however, then the digital quasi-RMS detector multiplies the rectified signal by a second time constant to generate a second filtered signal and sums the second filtered signal with the estimated present energy value to determine the approximate RMS energy.

摘要： A multi-channel synchronous compander for hearing aids, in which the input signal from an input transducer is directed through a 2:1 front compressor, then through a band splitting filter to divide it into a desired number of frequency bands, then through expander/compressors to provide selected expansion/compression of each frequency band depending on the user's hearing impairment. The outputs of the expander/compressors are summed, amplified and directed to the hearing aid output transducer. The compressor and each expander/compressor are all controlled by control signals derived from the compressed signal level at the output of the front compressor. The use of common control signals for both the front end compression and the expansion removes the need for close matching of temporal performance and improves the output signal fidelity. The front compressor allows the filter capacitors to be reduced in size so that they can be integrated. Sounds above a high level threshold do not change the gain applied to input signal, even when changes are made in the expansion/compression ratios of the expander/compressors.
