Webb27 nov. 2024 · Any acoustical or audio system has a noise floor, right down to and including the thermal noise inherent in wires (approximately -125 dBM). The noise floor of a recording is the sum of all the noise floors encountered during the recording process. Acceptable noise floor is -65db or lower. Above -75db and the noise gets in the way. In signal theory, the noise floor is the measure of the signal created from the sum of all the noise sources and unwanted signals within a measurement system, where noise is defined as any signal other than the one being monitored. In radio communication and electronics, this may include thermal noise, black body, cosmic noise as well as atmospheric noise from distant thunderstorms and similar and any other unwanted ma…
