Although noise induced hearing loss represents the number one occupational disease, individual workers’ noise exposure levels are still rarely precisely known and infrequently tracked. Indeed, standardized noise exposure campaigns have as their principle disadvantages the cost of instrumentation and the difficulties associated with ease of implementation. In opposition to these procedures informal noise surveys carried out with cheaper basic sound level meters do not hold enough statistical power.

WikiLeq project plans to propose an alternate solution with the use of smartphones :

An androidTM “app” provides geo-localized noise measurements that are sent to a central server for data analysis. A web application allows users to explore the noise exposure through a website or their smartphone.

Two simultaneous approaches are developed: the first one features a personal full work shift dosimetric assessment, while the other features a participative sound pressure levels mapping with innovative calibration method.
