The circuit may employ passive or active noise canceling techniques to filter out the noise, producing an output signal that has a lower noise floor and a higher signal-to-noise ratio .
FM systems can be used at school, work, and other public settings where background noise is loud or distracting. Read on for a closer look at how FM systems work, who they’re for, and what ...
Computerized feedback devices (such as CAFET or Dr. Fluency) use computer technology to increase control over breathing and phonation. A microphone gathers information about the stutterer’s speech and feedback is delivered on a computer screen. Measurements include intensity (loudness), voice quality, breathing patterns, and voicing ...
These programs reduce acoustic feedback (whistling), reduce background noise, detect and automatically accommodate different listening environments (loud vs. soft, speech vs. music, quiet vs. noisy, etc.), control additional components such as multiple microphones to improve spatial hearing, transpose frequencies (shift high frequencies that a ...
A throat microphone, also called a laryngophone, is a type of contact microphone that absorbs vibrations directly from the wearer's throat by way of single or dual sensors worn against the neck. The sensors, called transducers , can pick up speech even in extremely noisy or windy environments, such as on a motorcycle or in a nightclub .
For an added bonus, the hearing aids offer Bluetooth connectivity for hands-free calls and streaming your favorite music, podcasts and TV shows right to your hearing aid (iPhone 11 or newer ...
