The sound power level is independant on: the location of the equipment the environmental conditions, and the distance from the measurement point The sound power level can be considered as the more precise of the two. The sound power will have a higher value than the sound pressure, bon't be...

Sound pressure level (SPL)LpdB Directivity factorQ Distance to sound sourcerm ↓ Sound power level (SWL)LWdB Sound power or sound power level has nothing to do with the distance from the sound source. Thinking helps: A 100 watt light bulb is emitting constantly the same power. ...
Question in the title... I see values stated like this and dont know whether they mean sound power level or sound pressure level: Noise level (ISO 2151): 66dB(A
Sound - Hearing Threshold vs. Age Shift in hearing threshold for men and women vs. age. Sound Intensity Acoustic power of sound per unit area. Sound Power Sound power from sources like fans, jet engines, cars, humans and more. Sound Pressure ...
Sound power vs. sound pressure Sound sources such as machinery radiate acoustic power, and this createssound pressure. Sound pressure is the measurable effect, butsound poweris the cause. Unlike sound pressure, sound power does not depend on the acoustics of the surroundings, the noise from other...
Note: The radiated sound power (sound intensity) is the cause and the sound pressure is the effect, where the sound engineer is particularly interested in the effect. The effect of temperature and sound pressure: Sound pressure and Sound power – Effect and Cause. Acousticians and sound protect...
