9 / 9
ABD710sound pressure levelREAL_MEASURE_TYPE

logarithmical measure of the pressure of a sound wave relative to a reference level

ABN638relative humidityREAL_MEASURE_TYPE

ratio of the partial pressure p of water vapour in moist air to its partial pressure psat at saturation, at the same temperature

ABN640air pressureREAL_MEASURE_TYPE

absolute pressure of environmental air

ABN708weighted sound pressure level AREAL_MEASURE_TYPE

logarithm of the ratio of a given sound pressure to the reference sound pressure of 20 μPa, the sound pressure being obtained with the standard frequency weighting A

ABN709weighted sound pressure level BREAL_MEASURE_TYPE

logarithm of the ratio of a given sound pressure to the reference sound pressure of 20 μPa, the sound pressure being obtained with the standard frequency weighting B

ABN710weighted sound pressure level CREAL_MEASURE_TYPE

logarithm of the ratio of a given sound pressure to the reference sound pressure of 20 μPa, the sound pressure being obtained with the standard frequency weighting C

ABN711sound intensity levelREAL_MEASURE_TYPE

logarithm of the ratio of a given intensity of sound in a stated direction to the reference sound intensity. Such intensity level in decibels is ten times the logarithm to the base ten of the ratio
