"NettetThe Intensity Calculation The pressure gradient signal must now be integrated to give the particle velocity. The estimate of particle velocity is made at a position in the acoustic centre of the probe, between the two microphones. The pressure is also approximated at this point by taking the average pressure of the two microphones. " - Intensity level

Nettet4. mar. 2024 · If they represent a grey scene, the R, G and B values are the same in a pixel and thus only 256 different intensity levels can be represented. And then there is the look-up matter, of displaying your data range into the 256 intensity levels that a human eye already hardly, if at all, can distinguish. NettetThis level occurs when the measured intensity is equal to the reference level. i.e., it is the sound level corresponding to 0.02 mPa. In this case we have sound level = 20 log (p measured /p ref) = 20 log 1 = 0 dB. Remember that decibels measure a ratio. 0 dB occurs when you take the log of a ratio of 1 (log 1 = 0).
