Sound pressure level (SPL) or acoustic pressure level is a logarithmic measure of the effective pressure of a sound relative to a reference value. Sound pressure level, denoted Lp and measured in dB, is defined by.
Subsequently, one may also ask, what is the SPL?
Sound Pressure Level is normally abbreviated SPL. SPL is calculated in decibels or db. Please note that db is a relative term. It can refer to almost anything, however, the most well known is SPL.
What is SPL sound pressure level?
Sound pressure level uses a logarithmic scale to represent the sound pressure of a sound relative to a reference pressure, and it's measured in units of decibels (dB). The sound pressure level at the threshold of human hearing is actually 0 dB, which has the same pressure as the reference pressure, 2 x 10-5 Pa.
