Study Overview
Brief Summary
Aim: To study the influence of recreational noise exposure on cochlear synaptic functions in college-going students.
Objectives:
- To estimate the recreational noise exposure levels
- To assess the influence of recreational noise on ABR wave I latency, amplitude and FFR
- To study the association between recreational noise exposure and ABR and FFR
Justification for study: Listening difficulty and poor speech perception is common in cochlear synaptopathy, which is also reported by chronic recreational noise exposure individuals. However, till date the relationship is not established. Hence there is a need to see the influence and association of recreational noise and synaptic function.
Procedure: This study involves the administration of the Noise Exposue Structured Interview (Guest et al, 2018) to estimate a person’s lifetime noise exposure. After this individuals are grouped into 3 groups. Group 1- No noise/ occasional users of PLDs or recreational noise exposure, 2- Predominant PLD users, 3- Combined PLD and recreational noise exposure. Then Pure Tone Audiometry along with Extended High Frequency Audiometry and Speech-in-noise test are done. Otoacoustic emissions, Electrocochleography, ABR and Frequency Following Response will also be done.
