Description: Sound pressure level is actually a ratio of the absolute Sound Pressure and a reference level (usually the Threshold of Hearing or the lowest intensity sound that can be heard by most people).; Name: acoustic pressure level
Description: Ten times the logarithm to the base 10 of the ratio of the square of the sound pressure, p, to the square of a reference value, p0, expressed in decibels; Name: Sound pressure level
Description: The operating overpressure PS1+ is the maximum value of the operating overpressure defined from a safety point of view by the manufacturer of the system for the various components in relation to the atmospheric pressure (1 bar) at the maximum permissible temperature TS1; Name: Max. permissible overpressure PS1+ at TS1, room1
