Headsets worn over the ear with a soft ear-hook are known as over-the-ear headsets or earloop headsets. Convertible headsets are designed so that users can change the wearing method by re-assembling various parts. There are also under-the-chin headsets similar to the headphones that stenographers wear.
Audio feedback (also known as acoustic feedback, simply as feedback) is a positive feedback situation that may occur when an acoustic path exists between an audio output (for example, a loudspeaker) and its audio input (for example, a microphone or guitar pickup ). In this example, a signal received by the microphone is amplified and passed out ...
Automatic gain control ( AGC) is a closed-loop feedback regulating circuit in an amplifier or chain of amplifiers, the purpose of which is to maintain a suitable signal amplitude at its output, despite variation of the signal amplitude at the input. The average or peak output signal level is used to dynamically adjust the gain of the amplifiers ...
3. Working on each other when you should be solving the problem. "Trying to solve each other is war," Dr. Tatkin says. "Nothing will be accomplished except a fight." The words sound intense, but ...
Safety test. Hardware devices should always be tested if it is controlled by software which renders a microphone blocker useless. This can simply be done by plugging a headset or a microphone to the jack try to activate the internal microphone (eg with speaker mode on smartphones or feature phones and speak near the phone while keeping the microphone at distance or plugged), or any program ...
A sound reinforcement system is the combination of microphones, signal processors, amplifiers, and loudspeakers in enclosures all controlled by a mixing console that makes live or pre-recorded sounds louder and may also distribute those sounds to a larger or more distant audience. [1] [2] In many situations, a sound reinforcement system is also ...
Monaural sound or monophonic sound (often shortened to mono) is sound intended to be heard as if it were emanating from one position. [1] This contrasts with stereophonic sound or stereo, which uses two separate audio channels to reproduce sound from two microphones on the right and left side, which is reproduced with two separate loudspeakers ...
Headphones are a pair of small loudspeaker drivers worn on or around the head over a user's ears. They are electroacoustic transducers, which convert an electrical signal to a corresponding sound. Headphones let a single user listen to an audio source privately, in contrast to a loudspeaker, which emits sound into the open air for anyone nearby ...
