As for exact DB's I'm unsure, but mine is about the same as a well tuned lawn mower.
The noise level distance formula calculates the distance between two points based on their noise levels. It is typically represented as: Distance ((Noise level 1 - Noise level 2)2).
The sound level of the noise measured at 42 dB is considered moderate and is similar to the noise level of a quiet library.
To determine the level of noise in a circuit using a Johnson noise calculator, you need to input the resistance and temperature of the circuit into the calculator. The calculator will then provide you with the Johnson noise voltage, which represents the level of noise in the circuit.
The decibel noise level of a concrete breaker is at around 111 to 113. This can vary depending on what concrete breaker one is using, and might have a different noise level.
