High signal to noise

WebNoise may arise in signals of interest to various scientific and technical fields, often with specific features: Noise (audio), such as "hiss" or "hum", in audio signals. Background … WebApr 30, 2024 · A high microphone SNR helps keep the noise floor inaudible even when the signal is amplified. The longer the capturing distance, the lower the microphone self-noise should be to avoid problems. This is especially critical when the distance is long and the sound source itself is quiet.
