Examples of Sound Pressure in a sentence

  • The decibel (abbreviated as dB) scale reduces this ratio to a more manageable size by the use of logarithms.The symbols SPL, L or LP are commonly used to represent Sound Pressure Level.

  • The applicant may be required to provide Operating Sound Pressure Level measurements from a reasonable number of sampled locations at the perimeter of the battery energy storage system to demonstrate compliance with this standard.

  • The standard reference unit for Sound Pressure Levels expressed in decibels is 2 x 10-5 Pa.

  • At each of the slected locations, Sound Pressure Level (SPL) measurements were taken at an interval of 1 minute using a sound level meter of Lutron make Digital Sound Level Meter.

  • As with Sound Pressure Levels, Sound Power Levels are expressed in decibel units (dB or dBA), but may be identified by the symbols SWL or LW, or by the reference unit 10-12 W.The relationship between Sound Power and Sound Pressure is similar to the effect of an electric radiator, which is characterised by a power rating but has an effect on the surrounding environment that can be measured in terms of a different parameter, temperature.
