The level of noise that an audio device produces, measured in negative dB. The lower the dB level, the quieter the device is.
The residual level of noise in any system. In a well designed mixer, the noise floor will be a quiet hiss, which is the thermal noise generated by bouncing electrons in the transistor junctions. The lower the noise floor and the higher the headroom, the more usable dynamic range a system has.
Normally the lowest threshold of useful signal level (although sometimes audible signals below the noise floor may be recovered).
Expressed in dB, the level of random noise below the program signal.
The lowest number to accept as volume data from a trigger. Lighter hits are ignored. (FL) on the Zendrum.
In an electronic device, the sound level of undesired sounds generated by the device itself. How loud the background static generated by a device is. (All audio gear produces some amount of noise due to the thermal properties of components.)
The level of background noise in a signal or the level of noise introduced by equipment or storage media below which the signal can't be isolated from the noise.
The level of all the combined noise of an electronic device or component.
In every environment, there is a certain level of radio “noise” from a variety of sources that a service provider’s signal must exceed in power in order to be properly received.
The level at which noise (hiss, hum, etc.) exists in an amplifier. Often used as a reference point in signal-to-noise ratios.
The level of signal below which a receiver cannot detect a signal due to the noise generated within the receiver.
The lowest sound pressure levels present in a space over a period of time.
The noise generated by an audio device in the absence of any input signal.
(1) A cutoff point from which no appreciable information from a signal can be retrieved below. (2) The minimum discernible signal that can be detected by a receiver.
the lowest decibel of a signal which a system can render.
The noise value in the signal-to-noise (SNR) ratio for an environment. In general, the higher the noise floor, the more sensitive the engine will be to background noise.
In signal theory, the noise floor is the measure of the signal created from the sum of all the noise sources and unwanted signals within a measurement system.
