This system has a characteristic mass and stiffness, and a resonant frequency at which the system will vibrate freely. This frequency is known as the "free-space resonance" of the loudspeaker and is designated by F s. At this frequency, the voice coil is vibrating in the speaker's magnetic field with maximum peak-to-peak amplitude and velocity.
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 ...

It adds two additional speakers to the more conventional six-channel ( 5.1) audio configuration. As with 5.1 surround sound, 7.1 surround sound positional audio uses the standard front left and right, center, and LFE ...
