    The scale uses a hearing threshold of 2.0 10 -5 Pa. Sound Pressure Level (SPL) can be calculated by using the following equation Where. P = the measured sound pressure level. P 0 = the reference sound pressure which is 20μPa or 2.0 10-5 Pa or 2.9 10-9 psi. This gives a range of 0 to 120 dB (120 dB is the approximate threshold of pain).
