Sound Attenuation Calculator - Inverse Square Law | WKC Group
https://www.wkcgroup.com/tools-room/inverse-square-law-sound-calculator/
Sound Attenuation Calculator - Inverse Square Law. The formula to calculate sound attenuation over distance for a point source is: Lp (R2) = Lp (R1) - 20·Log10(R2/R1) Where: Lp (R1) = Known sound pressure level at the first location (typically measured data or equipment vendor data) Lp (R2) = Unknown sound pressure level at the second location ...

The sound pressure that is considered as a limit for the human audition is 2 · 10 -5 Pa. On the other hand, human ear pain threshold is about 200 Pa. It is a very wide range, so, to handle these quantities more easily the unit usually used is the decibel (dB), which is a logarithmic scale relative to a reference level. Lp = 20 log (P / Po)
Calculate Attenuation Circuit ( L-Pad ) - mh-audio.nl

The attenuation you want, in decibels (dB), with no negative sign. Example: 3dB, 6dB, 12dB, etc. (OPTIONAL) Amp/stereo maximum power: You can see the worst-case power ratings for the resistors needed at full input power. The calculator will display how much power each resistor will dissipate along with the power supplied to the speaker.
