Weighting filter - Telecommunications

A weighting filter is used to emphasise or suppress some aspects of a phenomenon compared to others, for measurement or other purposes. Weighting filter - Audio applications. In each field of audio measurement, special units are used to indicate a weighted measurement as opposed to a basic physical measurement of energy level. For sound, the unit is the phon (1 kHz equivalent level). Weighting filter - Loudness measurements. In the measurement of loudness, for exam ...

In each field of audio measurement, special units are used to indicate a weighted measurement as opposed to a basic physical measurement of energy level. For sound, the unit is the phon (1 kHz equivalent level). Weighting filter - Loudness measurements. In the measurement of loudness, for example, an A-weighting filter is commonly used to emphasise frequencies around 3–6 kHz where the human ear is most sensitive, while attenuating very high and very low frequencies to which the ear is insensitive. The ai ...

In the measurement of Gamma rays or other ionising radiation, a radiation monitor or dosimeter will commonly use a filter to attenuate those energy levels or wavelengths that cause the least damage to the human body, while letting through those that do the most damage, so that any source of radiation may be measured in terms of its true danger rather than just its 'strength'. The Sievert is a unit of weighted radiation dose for ionising radiation ...
