When using multiple fans with the same noise level, is there a way to calculate the total noise level?
Multiple fan noise calculation
It can be calculated as follows:
Combined noise level [dB] = noise from one fan + 10 log n
n: number of fans
Example: When using two 40 [dB] fans
Combined noise level [dB]= 40 + 10 log 2= 40 + 3
= 43 [dB]
