Effects of Multisession Anodal Electrical Stimulation of the Auditory Cortex on Temporary Noise-Induced Hearing Loss in the Rat
TLDR
A comparative analysis suggests that cochleotopic cholinergic neurotransmission is also better preserved after multisession epidural stimulation.
The efferent-mediated suppression of otoacoustic emissions in awake guinea pigs and its reversible blockage by gentamicin
TLDR
Noninvasive measurements of distortion-product otoacoustic emissions (DPOEs), which reflect outer hair cell function, are obtained in order to establish the characteristics of medial efferent-induced suppression in awake, restrained guinea pigs and provide an easy, noninvasive tool for studying auditory function with and without functioning efferents.
Protection from Acoustic Trauma Is Not a Primary Function of the Medial Olivocochlear Efferent System
TLDR
The paucity of high-intensity noise and the near ubiquity of low-level noise in natural environments supports the hypothesis that the MOC system evolved as a mechanism for “unmasking” biologically significant acoustic stimuli by reducing the response of the cochlea to simultaneous low- level noise.

Acoustic trauma: single neuron basis for the "half-octave shift".
TLDR
When pure-tone exposures were presented at frequency intervals measured from the neuron CF, then a frequency half an octave below the CF was the most effective for inducing a CF TTS, suggesting that the half-octave shift may well be a direct result of basilar membrane nonlinearities.
