Sound Intensity Level Addition

β_{t o t a l} = 10 lo g_{10} (\sum 1 0^{β_{i} /10})

How to add multiple sound sources in decibels (cannot simply add dB values).

Variables

β_total

Total sound level

Combined intensity level

βᵢ

Individual sound levels

Each source in dB

Convert each dB to intensity: I = I₀·10^(β/10), sum intensities, convert back to dB.
