Auditory Fatigue Clinical Trial
— EchoSamOfficial title:
Effects of Auditory Fatigue in Medical Regulation Assistants Working With Headset: Objective Measures
Auditory monitoring of employees is currently based on pure-tone audiometry. However, this
clinical examination does not prevent from deafness but established it a posteriori. From a
preventive standpoint, it is important to detect hearing professional pain before the
development of irreversible(s) clinical(s) symptom(s). The investigators' hypothesis is that
auditory fatigue results from damages of primary and secondary central auditory pathways
involving cognitive processes.
The assessment of auditory fatigue includes the evaluation of speech intelligibility,
short-term memory, working memory and perceived mental task load. The main objective of this
study is to identify, among regulating medical assistants working with headset, a central
auditory fatigue.
