The equivalent rectangular bandwidth or ERB is a measure used in psychoacoustics, which gives an approximation to the bandwidths of the filters in human hearing, using the unrealistic but convenient simplification of modeling the filters as rectangular band-pass filters, or band-stop filters, like in tailor-made notched music training (TMNMT).
The larger the critical bandwidth the lower the signal-to-noise ratio (SNR) and the more the signal is masked. ERB related to centre frequency: The diagram shows the ERB versus centre frequency according to the formula by Glasberg & Moore (1990). [8] [6] Another concept associated with the auditory filter is the equivalent rectangular bandwidth ...
A440 Play ⓘ. 440 Hz = 4.21 or 4.39. The Bark scale is a psychoacoustical scale proposed by Eberhard Zwicker in 1961. It is named after Heinrich Barkhausen, who proposed the first subjective measurements of loudness. [1]

The rules apply to US-made high bandwidth memory (HBM) technology as well as foreign-produced ones, though some exceptions could be made. ... 'Last Christmas' tops UK charts for 2nd-consecutive ...
This is a list of interface bit rates, is a measure of information transfer rates, or digital bandwidth capacity, at which digital interfaces in a computer or network can communicate over various kinds of buses and channels. The distinction can be arbitrary between a computer bus, often closer in space, and larger telecommunications networks.

For this calculation, it is conventional to define a normalized rate = / (), a bandwidth utilization parameter of bits per second per half hertz, or bits per dimension (a signal of bandwidth B can be encoded with dimensions, according to the Nyquist–Shannon sampling theorem). Making appropriate substitutions, the Shannon limit is:
