Modulation of auditory signal-to-noise ratios by efferent stimulation.
One of the primary challenges that sensory systems face is extracting relevant information from background noise. In the auditory system, the ear receives efferent feedback, which may help it extract signals from noise. Here we directly test the hypothesis that efferent activity increases the signal-to-noise ratio (SNR) of the ear, using the relatively simple teleost ear. Tone-evoked saccular p...
متن کاملEffect of signal to noise ratio on the speech perception ability of older adults
Background: Speech perception ability depends on auditory and extra-auditory elements. 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. In this study, the importance of SNR magnitude as an extra-auditory effect on speech...
متن کاملSignal-to-noise Ratios for Television Transmission
This note is concerned with the effects of random noise interference in television transmission systems. Such systems are finding increasing application in surveillance and telefactor systems. Numerous results which have been scattered throughout the literature are collected and unified. Three topics are covered: 1. The calculation of the video signal-to-noise ratio for the commonly used televi...
متن کاملTop-Down Influences of the Medial Olivocochlear Efferent System in Speech Perception in Noise
One of the putative functions of the medial olivocochlear (MOC) system is to enhance signal detection in noise. The objective of this study was to elucidate the role of the MOC system in speech perception in noise. In normal-hearing human listeners, we examined (1) the association between magnitude of MOC inhibition and speech-in-noise performance, and (2) the association between MOC inhibition...
متن کاملRight-ear advantage drives the link between olivocochlear efferent 'antimasking' and speech-in-noise listening benefits.
The mammalian cochlea receives feedback from the brainstem medial olivocochlear (MOC) efferents, whose putative 'antimasking' function is to adjust cochlear amplification and enhance peripheral signal detection in adverse listening environments. Human studies have been inconsistent in demonstrating a clear connection between this corticofugal system and behavioral speech-in-noise (SIN) listenin...
