See also: auditory brainstem response. Bone-conduction auditory brainstem response (BCABR) are similar to air conduction auditory brainstem responses, with the main difference being that the signal is transmitted via bone-conduction instead of air. The goal of bone ABR is to estimate cochlear function and to help identify the type of hearing ...
Transient response. In electrical engineering and mechanical engineering, a transient response is the response of a system to a change from an equilibrium or a steady state. The transient response is not necessarily tied to abrupt events but to any event that affects the equilibrium of the system. The impulse response and step response are ...
The commonly stated range of human hearing is 20 to 20,000 Hz. [5] [6] [note 1] Under ideal laboratory conditions, humans can hear sound as low as 12 Hz [7] and as high as 28 kHz, though the threshold increases sharply at 15 kHz in adults, corresponding to the last auditory channel of the cochlea.

The proximity effect in audio is an increase in bass or low frequency response when a sound source is close to a directional or cardioid microphone. [1] [2] Proximity effect is a change in the frequency response of a directional pattern microphone that results in an emphasis on lower frequencies. It is caused by the use of ports to create ...
The frequency following response ( FFR ), also referred to as frequency following potential ( FFP) or envelope following response ( EFR ), is an evoked potential generated by periodic or nearly-periodic auditory stimuli. [1] [2] Part of the auditory brainstem response (ABR), the FFR reflects sustained neural activity integrated over a ...
Noise-cancelling headphones often combine sound isolation with ANC to maximize the sound reduction across the frequency spectrum. Noise cancellation can also be used without sound isolation to make wanted sounds (such as voices) easier to hear. Noise cancellation to eliminate ambient noise is never passive because of the circuitry required, so ...
