Acoustic measurements by drone: a SIM innovation …

In many industrial sectors, noise and vibration control is a strategic issue. Identifying and analyzing sound sources located at height, in confined areas or in hazardous spaces can be complex, if not impossible, using conventional means. Thanks to the integration of drones, SIM Engineering offers an innovative approach that revolutionizes industrial acoustic studies and enhances the effectiveness of acoustic diagnostics.

The problem of hard-to-reach sound sources

On industrial sites, certain acoustic emissions come from areas that are incompatible with the use of nacelles or conventional means of access. These constraints apply to thenuclear andpetrochemicalindustries, as well as to wastewater treatment plants and ICPE industrial sites. In these environments, team safety and business continuity are top priorities. Yet, without reliable measurements, it becomes impossible to define noise reduction solutions, guarantee the acoustic protection of equipment or ensure compliance with regulatory requirements.

The innovative solution: acoustic measurements by drone

To meet this challenge, SIM Engineering integrated the use of drones equipped with dedicated sensors. This technology enables access to complex or dangerous areas without interrupting site activity. It enables fast, reliable measurements, while reducing logistical and safety constraints.

The data collected is then processed by an advanced digital filtering system, designed to suppress the drone’s own frequency signature. The result: clean, usable measurements, perfectly integrated into an overall process of digital acoustic simulation, acoustic modeling, etc.

Reliable, precise acoustic engineering methodology

Beyond simple measurement, the drone approach is part of a comprehensivenoise and vibration engineering process. After data acquisition, SIM Engineering teams carry out a noise and vibration analysis, taking into account the site’s regulatory and operational constraints.

This analysis leads to the production of a detailed report including :

• models to locate and characterize sound sources,

• concrete recommendations for optimizing acoustic performance,

• industrial acoustic treatment or environmental noise reduction solutions tailored to specific needs.
