● Combining Decibels − up to 30 s ●
adding - summing up to 30 incoherent noise sources
The decibel calculator can be used to combine the s of up to thirty incoherent
electric or acoustic sources when theof each source is known in decibels (dB).
Fill in as many soundboxes as necessary and then click the calculate bar,
to get the calculated sum. Provided that each sound source has its own random phasing.
The formula for calculating the combining of two levels L1 and L2 is:
Combining decibels of one-third octave bands to level of one octave band and vice versa
Total adding of up to ten (10) incoherent sources
