Adding insult to injury: cochlear nerve degeneration after "temporary" noise-induced hearing loss.

The Journal of neuroscience : the official journal of the Society for Neuroscience · 2009

The seminal finding: a 'temporary' noise-induced threshold shift that fully recovers still leaves permanent, silent damage, acute loss of nerve terminals and delayed degeneration of the cochlear nerve.

Cochlear synaptopathy in acquired sensorineural hearing loss: Manifestations and mechanisms.

Hearing research · 2017

Review: well before hair cells die and thresholds rise, noise and aging silently sever the synapses between inner hair cells and the auditory nerve.
