Generally, a signal with an SNR value of 20 dB or more is recommended for data networks where as an SNR value of 25 dB or more is recommended for networks that use voice applications. Learn more about Signal-to-Noise Ratio.
Read moreWhat is a good signal-to-noise ratio in dB?
15 dB to 25 dB: is typically considered the minimally acceptable level to establish poor connectivity. 25 dB to 40 dB : is deemed to be good. 41 dB or higher: is considered to be excellent.
Read moreWhat is signal-to-noise ratio formula?
SNR refers to the ratio between the power of the desired output signal and the background noise, which is described as SNR dB = 2 log 10 V signal V noise , where Vsignal and Vnoise are the measured signal voltage and noise voltage, respectively.

A low self-noise rating is essential when capturing quiet sound sources (15 dBA or less), so a “good” SNR would be 79 dB or more .
