Effects of Compressed Sound on Hearing

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

The COMPRESSED project is an observational study that investigates the auditory effects of exposure to manipulated sounds, such as compression and filtering, on individuals who have varying levels of exposure to sound processing systems. Participants are divided into two groups: those with high exposure from professional activities and those with moderate exposure from educational settings. The study employs a range of audiological assessments, including self-assessments and objective tests, to evaluate the impact of sound dynamics on auditory perception. Conducted by the Institut Pasteur and Haute École Léonard de Vinci, this bi-centric study aims to enhance understanding of how sound manipulation affects hearing.

Why it matters

Who can join: the full rules

Inclusion Criteria:

For all participants:

* Age 18 or over,
* Work with platforms using sound signal processing systems,
* Fluent in English,
* Fluent in French,
* Declare that they have no hearing loss.

For participants in the high exposure group:

\- Have had a professional activity over the last three years using broadcasting platforms with sound signal processing systems,

For participants in the moderate or limited exposure group:

\- Have worked between one semester and two years with platforms using sound signal processing systems.

Exclusion Criteria:

* Conductive or mixed hearing loss, i.e. where the hearing loss affects both the outer and/or middle ear and the inner ear.
* Have an asymmetric hearing loss, i.e. a difference in average hearing loss between the left and right ear of more than 20 dB,
* Have a history of otitis and/or an ENT disease that permanently affects hearing (vestibular schwannoma, Ménière's disease, sudden or fluctuating deafness, congenital hypoacusis),
* Not fluent in English
* Be under guardianship,
* Deprived of liberty by judicial or administrative decision, or subject to legal protection.
