The signal- to-noise ratio (SNR) is an extra-auditory element that has an effect on the ability to normally follow speech and maintain a conversation. Speech in noise perception difficulty is a common complaint of the elderly.
Estimation of Signal-to-Noise Ratios in Realistic Sound ...
https://pubmed.ncbi.nlm.nih.gov/25690777/
For speech-in-babble noise, the average SNR was approximately 5 dB. The estimation uncertainty was generally low but became higher in highly fluctuating noises and at very low SNRs. Conclusions: The estimated SNRs were higher than previously reported. The results can be used in the design and evaluation of hearing-device features.

https://pubmed.ncbi.nlm.nih.gov/11425138/
This study examined the interactive effects of signal-to-noise ratio (SNR), speech presentation level, and compression ratio on consonant recognition in noise. Nine subjects with normal hearing identified CV and VC nonsense syllables in a speech-shaped noise at two SNRs (0 and +6 dB), three presentation levels (65, 80, and 95 dB SPL) and four compression ratios (1:1, 2:1, 4:1, …

Signal-to-noise ratio advantage of binaural hearing aids and directional microphones under different levels of reverberation. The signal-to-noise ratio necessary for a constant performance level was determined for normally hearing and hearing-impaired subjects under three levels of reverberation (0.3, 0.6, and 1.2 s) with monaural and binaural hearing aids having directional …

The amount of noise reduction is dependent on the approximate signal-to-noise ratio for each channel and the noise reduction setting. Noise reduction is greatest with a low signal-to-noise ratio, i.e. +5 S/N (signal is 5 dB greater/louder than the noise). Less noise reduction is applied as the signal-to-noise ratio becomes more positive or improves, i.e. +10 S/N.
Signal-to-Noise Ratio - an overview | ScienceDirect Topics
https://www.sciencedirect.com/topics/physics-and-astronomy/signal-to-noise-ratio
The signal-to-noise ratio in many high resolution spectroscopy measurements is now limited by the standard quantum noise or shot noise. This noise arises from a Heisenberg inequality relating the two-phase quadrature components of the electric field. Following investigations in the field of quantum optics, it has been proposed to generate ...

Douglas Beck, AuD, Donald J. Schum, PhD. Directional hearing aids can improve the signal-to-noise-ratio (SNR) of speech occurring in a noisy background. Amplification of background noise is one of the most significant consumer-based complaints associated with hearing aids. Although other technologies (FM systems, direct audio input, assistive listening …

Noise reduction coefficient—a measurement of the ability of a material to absorb sound. Signal-to-noise ratio (SNR)—a comparison of a desired signal (sound) to the level of background noise. This measurement can be used to determine the level of speech intelligibility within a room (and in specific parts of a room).
