A-weighting is the most commonly used of a family of curves defined in the International standard IEC 61672:2003 and various national standards relating to the measurement of sound pressure level. A-weighting is applied to instrument-measured sound levels in an effort to account for the relative loudness perceived by the human ear, as the ear is less sensitive to low audio frequencies. It is ...

Telecommunications. In the field of telecommunications, weighting filters are widely used in the measurement of electrical noise on telephone circuits, and in the assessment of noise as perceived through the acoustic response of different types of instrument (handset). Other noise-weighting curves have existed, e.g. DIN standards.
2022年4月5日 · The A-weighting curve is the most common weighted sound curve. It is considered the standard for general purpose measurement. Although they are less used in engineering, other frequency weighting curves can be applied for specific needs, generally for higher sound levels. B-weighting matches the 70-phon equal-loudness contour, which corresponds ...
A-Weighting. An electrical filter which used when taking audio measurements of equipment, and designed to mimic the relative insensitivity of the human ear to high and low frequencies at low sound pressure levels (notionally 40 Phons or about 30dBA SPL). Essentially, the filter rolls-off the low frequencies below about 700Hz and the highs above ...
