Declared properties9#
logarithmical measure of the pressure of a sound wave relative to a reference level
ratio of the partial pressure p of water vapour in moist air to its partial pressure psat at saturation, at the same temperature
absolute pressure of environmental air
temperature of environmental air
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
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
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
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
sound intensity for stating the sound intensity level
