WebMar 7, 2024 · Speech perception in noise can be analysed from at least two aspects - intelligibility and quality. I assume by understanding speech you mean intelligibility, that is you can make out the phonemes uttered. Intelligibility in noise is dependent on the power spectral density of noise. WebThe effect of signal-to-noise ratio (SNR) on linguistic processing ability is relatively unknown for either young (YAs) or older adults (OAs). Purpose: To determine if reduced SNRs would be more deleterious to the linguistic processing of OAs than YAs, as measured by accuracy and reaction time in a semantic judgment task in competing speech.

"WebThe relationship between sound and noise levels is generally described in terms of a signal-to-noise ratio. With a background noise level between 35 and 100 dB, the threshold for 100% intelligibility is usually a signal-to-noise ratio of 12 dB. [3] 12 dB means that the signal should be roughly 4 times louder than the background noise. " - Speech to noise ratio
