A microphone is an acoustic-to-electric transduceror sensor that converts sound into an electrical signal.
An unwanted signal is noise.
Signal to noise ratio is a measure of signal strength to the background noise. Engineers use the signal to noise ratio to improve digital signal processing.
A noise generator produces electrical signals in both audio and video format. These are used for troubleshooting purposes in signal circuits for amplifiers and televisions.
Noise signal is any signal which interferes with the main signal and does not give any important information.Signal should always be twice to that of noise.
noise reducing from signal by some method?
No. It is not possible to determine if someone is listening in on a radio transmission, with or without noise. The only protection you have is to scramble the signal.

Shot noise is a type of random electrical noise that occurs in electronic devices due to the discrete nature of electric charge. It can affect the performance of electronic devices by introducing fluctuations in the signal, which can impact the accuracy and reliability of the device's operation. In general, higher levels of shot noise can degrade the performance of electronic devices by reducing their signal-to-noise ratio and increasing errors in signal processing.
If the SNR is too low, the signal cannot be distinguished from the noise. The signal must be boosted, or noise must somehow be removed.
A repeater that is able to distinguish between noise and signal. It reads the signal and retransmits it without the accompanying noise.
