amplifier inserted into the incudo-stapedial joint gap. They examined if this is possible and discerned the advantages and disadvantages of the design. These investigators examined a 10:1 scale model of a prospective implantable hearing aid comprising 1 piezoelectric sensor and 2 independent ...
The ITE aid makes use of electronic miniaturization to place the amplifier and speaker in a small casing that fits into the ear canal. The faceplate of the ITE aid is located in the opening to the ear canal. The microphone is located in the faceplate. This provides a more “natural” loc...
Mild-to-moderate hearing losses were fit with either of two models: a hearing aid built into the temple piece of an eyeglass frame or an aid that hangs behind-the-ear (BTE) and connects to an earmold with soft plastic tubing. The electronics consisted of a linear amplifier, and the ...

Hearing damage was even more of a concern for me when designing the new McIntosh XR speakers. When the ML speakers were being designed in 1968, the McIntosh MC2105 power amplifier was also in the design stages. That was 100 watts per channel and was a lot of power for a home amplifier...
ON-DEVICE VOLUME CONTROLS: Each hearing aid has a toggle switch to raise and lower volume, allowing you to set a different volume level on each hearing aid. There’s also a separate button to switch between preset listening environments. REPLACEABLE BATTERIES: Replaceable 312 zinc-air...
A hearing compensation system for the hearing impaired comprises an input transducer for converting acoustical information at an input to electrical signals at an output, an output transducer for converting electrical signals at an input to acoustical in
are among the most used treatments for hearing loss. It is estimated that nearly 29 million American adults could benefit from using hearing aids. Hearing aids have three basic parts: microphone, amplifier, and receiver (speaker). The hearing aid receives sound through the microphone, amplifies th...
PURPOSE:To eliminate soldering process at the stage of assembly and enhance the effectiveness in assembly operations by mounting an earphone on a flexible circuit board, on which electronic parts constituting a hearing-aid signal processing circuit are mounted. CONSTITUTION:In a hearing-aid signal proc...
There is disclosed a hearing aid amplifier which employs a gain control circuit selectively operative to vary the gain of the amplifier when a predetermined intensity sound signal is applied to the hearing aid incorporating the amplifier. The gain of the amplifier is varied when the intensity of ...
