Web30 apr. 2024 · Signal to Noise Ratio (SNR) Noise in the output of a microphone can be defined as any signals, which are not the intended input source and is generally … WebSNR is the ratio of a reference signal to the noise floor of the microphone. A microphone’s SNR is the difference between its inherent self noise level and a standard reference pressure, specifically 94 dB SPL (1 Pa) at 1 kHz. You will typically see this specification presented as an A-weighted value (dBA) with a 20 kHz bandwidth.
