A-weighting definition

A-weighting means the frequency weighting characteristic as specified in the International Electrotechnical Commission (IEC) Standard 61672, and intended to approximate the relative sensitivity of the normal human ear to different frequencies (pitches) of sound. It is denoted as “A”;
A-weighting means a filter network designed to transform a frequency spectrum to that which is heard by the human ear.
A-weighting means making graded adjustments in the intensities of sound of various frequencies for the purpose of noise measurement, so that the sound pressure level measured by an instrument reflects the actual response of the human ear to the sound measured.

A-weighting means the standard A-weighted frequency response of a sound level meter, which de-emphasizes low and high frequencies of sound in a manner similar to the human ear for moderate sounds.
A-weighting means a frequency response adjustment of a sound level meter with an American National Standards Institute (ANSI) defined A-weighting filter. The A-weighting filter approximates the human ear’s response to various frequencies. Measurements made with this weighting are designated dBA.

A-weighting means that portions of the frequency spectrum of a sound have been increased or attenuated to correspond to the frequency response of the human ear. A typical noise source will generate sound made up of different frequencies. "Frequency" means the rate at which a sound source will cause the surrounding air to vibrate. Humans perceive the frequency of a sound as its "pitch."
A-weighting means a frequency weighting applied to measure or predict sound levels in order to compensate for the non-linearity of human hearing;
