Distance Attenuation Explanation

Distance Attenuation Explanation ● The reduction in sound pressure level as the distance from the sound source increases. Point source SPL₁- SPL₂= 20log(r₂/r₁) Line source SPL₁- SPL₂= 10log(r₂/r₁) SPL: Sound Pressure Level (dB), r: Distance Example When the distance between a point source and a free sound source is 5m, and the sound pressure level is 88dB, what will be the sound pressure level w..
