3 important questions on The built environment and sound - Calculating on decibels
What formula is used to add sound pressure levels?
L_p1+2 = 10log(10^(L_p1/10)+10^(L_p2/10))
How much higher is the sound pressure level of three equally strong sounds
5 dB (about)
What is the sound pressure if two sound pressure levels differ 10 dB or more?
The overall sound pressure level will be equal to the highest pressure level
