RT60 Reverb time Reverberation time to sound decay rate ...
http://www.sengpielaudio.com/calculator-decayrate.htm
The decay rate is the time rate at a stated frequency, at which sound pressure level decreases in a room. The unit is decibel per second (dB/s). The unit is decibel per second (dB/s). The decay time is that elapsing time, in which the sound pressure level from a value to another drops; both values, the initial value and the goal value must be ...
How does the sound decrease with distance? sound …
http://www.sengpielaudio.com/calculator-SoundAndDistance.htm
Sound power or sound power level has nothing to do with the distance from the sound source. Thinking helps: A 100 watt light bulb is emitting constantly the same power. That is really the case - no matter if in 1 m, in 10 m, or even in 100 distance. These emitted watts don't change with distance. They stay in the source.

http://www.sengpielaudio.com/calculator-distance.htm
So, if we double the distance, we reduce the sound pressure by a ratio of 2 and the sound intensity by a ratio of 4. In other words, we reduce the sound level by 6 dB. If we increase r by a ratio of 10, we decrease the level by 20 dB. The sound intensity level and …
Sound power level SWL and sound pressure level SPL ...
http://www.sengpielaudio.com/calculator-soundpower.htm
All share as level the same unit of measure: the decibel (dB). The term "sound level" is commonly substituted for each. As characteristic impedance of air we use the round value Z = 400 N·s/m³ (Pa·s/m). Then the "sound level", that is the sound pressure level L p and the sound intensity level L I is exactly the same as a decibel value. The sound power or acoustic power is the sound …

Reverberation time (RT) is a measure of the amount of reverberation in a space and equal to the time required for the level of a steady sound to decay by 60 dB after the sound has stopped.The decay rate depends on the amount of sound absorption in a room, the room geometry, and the frequency of the sound. RT is expressed in seconds. This decay is usually measured over the …

The decay rate depends on the amount of sound absorption in a room, the room geometry, and the frequency of the sound. RT is expressed in seconds. This decay is usually measured over the first 10, 20 or 30 dB and then extrapolated to the full 60 dB range. Credit: Calculation of the reverberation time.
Distance Attenuation: How Sound Reduces with Distance
https://www.acoustical.co.uk/distance-attenuation/how-sound-reduces-with-distance-from-a-point-source/
This means that the same sound energy from the source is distributed over a larger area and the energy intensity reduces with the square of the distance from the source (Inverse Square Law). For every doubling of distance, the sound level reduces by 6 decibels (dB), (e.g. moving from 10 to 20 metres away from a sound source). But the next 6dB ...
2.9 How does sound decay with distance - stason.org
https://stason.org/TULARC/physics/acoustics-faq/2-9-How-does-sound-decay-with-distance.html
Description. This article is from the Acoustics FAQ, by Andrew Silverman with numerous contributions by others.. 2.9 How does sound decay with distance ? The way sound changes with distance from the source is dependent on the size and shape of the source and also the surrounding environment and prevailing air currents.
