Acoustic – noise measurement
The 6NAPSE Group supports you on acoustic and noise measurement, in order to design products with the lowest possible noise level, via acoustic testing.
Automobile and rail transport, household appliances (e.g. vacuum cleaner), refrigeration systems or industrial machinery and tools produce noise levels that vary over time and cause noise pollution for the environment and the population.
What is an acoustic measurement ?
An acoustic measurement is the recording of a noise emitted by its systems via microphone sensors. This measurement allows the characterization of noise in terms of amplitudes and frequencies. Its purpose is to design products with a lower noise level.
Acoustic measurement in the test center or on the track
The 6NAPSE Group supports manufacturers and individuals in acoustic measurement in different phases of product life.
In order to meet the needs of our customers in a broad way and to satisfy their expectations, the 6NAPSE Group has a large equipment fleet.
- Semi-anechoic chamber to place the product in free field condition
- Microphone sensors for recording
- Sound level meter to measure sound pressure levels
- Acoustic heads to absorb noise
- Aero-acoustic flow bench for measuring noise due to air flow.
- Alpha cabin to measure the sound absorption coefficient in diffuse fields
- Impedance tube to measure absorption and TL (Transmission Loss / Attenuation Index)
Applications
- Measure the insertion loss (deck crossing) with the small cabin
- Measure the noise inside a passenger compartment
- Measure the noise of vehicles emitted outdoors (sound level of vehicles in normal driving in urban traffic) according to standard ECE/trans/WP.29/2015/62
- Diagnosis, characterization in level and frequency of a product and proposal of solutions to improve the product
- Characterize the materials by determining the transmission loss (Alpha cabin / impedance tube)
Associated services
