WebFormulas to calculate the sound level L in dB (sound pressure level or sound intensity level) in dependence of the distance r. Sound pressure level (dB) = Sound intensity level (dB) Sound pressure is not Sound intensity Often we talk only of sound level. However, sound pressure as a sound field WebTable 17.2 Sound Intensity Levels and Intensities. The decibel level of a sound having the threshold intensity of 10 – 12 W/m 2 is β = 0 dB, because log 10 1 = 0. That is, the threshold of hearing is 0 decibels. Table 17.2 gives levels in decibels and intensities in watts per meter squared for some familiar sounds.
