Acoustic tests
Validate the acoustic performance of your materials and equipment
Why carry out acoustic testing?
- Ensure compliance with international acoustic requirements (NF EN ISO, MIL-STD, DCN SEFC 17-50, etc.).
- Reduce noise pollution and improve the acoustic comfort of products.
- Characterisation of noise sources to optimise system design.
- Validate equipment under real conditions of use.
Types of acoustic and vibro-acoustic tests
Our laboratories are equipped to carry out a range of acoustic tests tailored to your needs:
Sound characterization tests
- Sound level measurement (dB): Characterization of noise levels.
- Frequency spectra: Analysis of acoustic signatures to identify noise sources.
- Reverberation time and sound absorption.
Noise and vibration testing (NVH)
- Analysis of structural noise and vibration.
- Combined acoustic and mechanical measurements.
Semi-anechoic chamber testing - CSA
- Free field measurements to eliminate stray reflections.
- Testing of equipment under simulated environmental conditions
What sectors are involved in these trials?
Automotive
Aerospace
Industry
Rail
Defence
