This article looks at the possible causes for Cochlear Synaptopathy or Hidden Hearing Loss in individuals with a history of noise exposure. It suggests that noise exposure which does not cause a permanent threshold shift, can cause other permanent changes to structures along the auditory pathway and the synapses between them.
The aim of this module is to provide an overview of noise induced hidden hearing loss and the possible causes of this disorder.
This article points out the danger of noise exposure and that even if the effects appear reversible at first, they can cause damage to the synapses and this can affect hearing or speech perception in the future.
Upon completion of this module practitioners should have a clear understanding of:
- The definition of Noise Induced Hidden Hearing Loss.
- The mechanism of noise induced synaptic damage .
- The reversibility of synaptic damage.
- The causes of cochlear coding deficits in Hidden Hearing Loss .
- The association between coding deficits and unhealthy synaptic repair.
- The need for research in laboratories in the future.
