Free Online dB Calculator How to find Sound Intensity Levels?

WebThe decibel level of a sound having an intensity of 10 –12 W/m 2 is β = 0 dB, because log 10 1 = 0. That is, the threshold of human hearing is 0 decibels. Each factor of 10 in intensity corresponds to 10 dB. For example, a 90 dB sound compared with a 60 dB sound is 30 dB greater, or three factors of 10 (that is, 10 3 times) as intense. Web"Sound level" is the sound pressure level in dB SPL or the sound intensity level in dB SIL. For Pa say, Pascal. This is the size for the pressure p = force F by area A. The reference sound pressure is p 0 = 20 µPa = 2×10 −5 Pa. The reference sound intensity is I 0 = I 0 = 10 −12 W/m 2. Web= 140 dB. Example - Sound Power from a Fan. A fan creates 1 W of sound power. The noise level from the fan in decibel can be calculated as. L = 10 log ((1 W) / (10-12 W)) = 120 dB. Example - Sound Intensity and Decibel. The difference in decibel between sound intensity 10-8 W/m 2 and sound intensity 10-4 W/m 2 (10000 units) can be calculated as e. w. hornung written works
