| 6397037 | Method and apparatus for improving classroom amplification systems and other RF-type amplification systems An RF-type amplification system, such as a classroom amplification system, employs technology adapted from a cordless telephone system to overcome interference. The amplification system includes a portable remote unit (87) and a base unit (82). Remote uni... | 05/28/2002 |
| 5794187 | Method and apparatus for improving effective signal to noise ratios in hearing aids and other communication systems used in noisy environments without loss of spectral information Improved signal to noise ratio to help speech comprehension in a noisy environment is accomplished by selectively downwardly expanding a speech and noise composite signal when the speech signal is absent, thereby lowering signal components which represent... | 08/11/1998 |
| 5388992 | Method and apparatus for tactile transduction of acoustic signals from television receivers Inexpensive wideband transducers convert low frequency components (i.e., approximately 50 Hz through 800 Hz) of an audio signal to mechanical vibrations at the same frequencies so that the vibrations may be perceived at the user's skin, typically at a han... | 02/14/1995 |
| 5289544 | Method and apparatus for reducing background noise in communication systems and for enhancing binaural hearing systems for the hearing impaired Directional hearing in noisy environments is enhanced using small conventional microphones. In one embodiment a conventional first order bidirectional gradient microphone is employed in connection with a barrier to produce sound shadow at the rearward end... | 02/22/1994 |
| 4461025 | Automatic background noise suppressor A circuit for suppressing background noise of a continuous nature while enhancing speech signals, or signals having the transient temporal qualities of speech, includes a signal multiplier which, in the preferred embodiment, receives the composite audio s... | 07/17/1984 |
