  • Hearing aid and system for use with cellular telephones
    Patent number: 5768397
    Abstract: The light output of an IR LED mounted on a cellular telephone is modulated by the audio output of the telephone and made incident upon a photodiode mounted to an ITE-type or canal-type hearing aid. The electrical signal output from the photodiode is routed through a bandpass filter, demodulated in a demodulator and amplified and/or processed in the hearing aid circuit.

  • Zinc-air dry cell holder and hearing aid that uses it
    Patent number: 5724431
    Abstract: A holder hermetically seals less than all of the air holes in a zinc-air dry cell and allows air to reach at least of the air holes. This greatly lengthens the lifespan of a zinc-air dry cell.

  • Hybrid behind-the-ear and completely-in-canal hearing aid
    Patent number: 5606621
    Abstract: A hybrid BTE and CIC hearing aid has a BTE component which is worn behind the patient's ear and a CIC component which is worn in the bony portion of the patient's ear canal. The BTE and CIC components are connected together with a wire cable. Electroacoustic feedback is reduced or eliminated, allowing gain to be increased. The patient is not disturbed by the occlusion effect.

  • Circuit for use in programmable hearing aids
    Patent number: 4947433
    Abstract: A circuit for use in programmable hearing aids is programmed by inputting digital pulses along two input lines. The programmed information is stored in ring counters and then registered in EEPROMS. A multiplexer (itself a ring counter) selects the ring counter which will be incremented by pulses input to one of the input lines.

  • Hearing aid and method for making it
    Patent number: 4860362
    Abstract: The shell of a hearing aid has an open end with a mating surface. The mating surface mates with a non-planar faceplate. Advantageously, the faceplate is shaped as a part of a sphere. Further advantageously, the surface is shaped by grinding.

  • Hearing aid noise suppression system
    Patent number: 4750207
    Abstract: A hearing aid responds to increased noise by changing its frequency response to reduce the effects of the noise. The hearing aid has a circuit which varies the frequency response of the unit as a function of low-frequency sounds, using a fast attack time and a much slower release time.

  • Resonant peak control
    Patent number: 4689818
    Abstract: A hearing aid having a microphone, an amplifier and a receiver for delivering the amplified sound to a user's ear, in which an adjustable resonant peak control is used to shift the frequency response of the amplifier to a lower frequency range in order to reduce feedback without substantial reduction in high frequency amplification or saturation levels.
