Automotive Test Enclosure (STC 48)
Sound isolation (TL), on average, about 48 decibels
Acoustic Test Enclosure for Car Seat Testing
MECART provided a modular, soundproof STC 48 chamber that exceeded the required STC 38 rating, ensuring effective isolation from the 85 dB ambient noise.
Key Project Highlights:
- Plug-and-play solution with minimal on-site handling
- Absorbing modular panels to reduce internal reverberation
- Designed for longevity (25+ years) and relocatable
- Equipped with STC-48 galvanized steel sliding doors
- Automatic pneumatic door system for frequent use (60 times/hour)
- Non-combustible panel construction
Turnkey Car Seat NVH Testing
In this case, this client needs an NVH testing enclosure to monitor the car seat vibrations, and they wanted minimal handling on site. They wanted a «plug and play», which is one of the reasons why they decided to select Mecart’s turnkey modular solutions. There is no need to say that the noise in an automotive manufacturing facility can be boisterous, especially when you need to monitor noise and vibration. The noise level inside the operating facility is around 85 decibels, way above the acceptable level for performing an NVH test.
For the car seat NVH testing, the acoustic enclosure needs to have an STC 38 (38 decibels) sound isolation inside. To reach this sound reduction level, MECART provided them with a soundproof STC 48 NVH test chamber. The walls and ceilings are made with absorbing modular panels to avoid reverberation inside the noise, vibration, and harshness testing enclosure.
The automotive company located in Ontario, Canada, was looking for a solution that would stand the test of time and could be operating for many years to come. MECART’s modular panels are built and designed with that in mind. This NVH test enclosure will be up and running for the next 25 years and probably beyond that! Even if they move to another complex or facility, they can bring it with them.
The 10’ x 7’ NVH test chamber was assembled at MECART’s facility before being delivered to the automotive factory. One of the design’s challenges was that the NVH acoustic enclosure needed to open 60 times an hour for 480 times over an 8-hour work shift. To ensure that it would resist that amount of usage, MECART equipped the NVH test enclosure with STC-48 galvanized steel sliding doors.
They open smoothly thanks to an automatic pneumatic system attached to them without compromising the car seat testing’s required sound attenuation. Mecart experience with other NVH test chambers has made it possible to meet this automated pneumatic sliding doors challenge. It should also be noted that all our panels are non-combustible.
