Modular Semi-Anechoic Chamber (MSAC)
No.1 Share in JAPAN
Modular Semi-Anechoic Chamber is used for measuring sound power in vehicles, NVH ( Noise, Vibration, and Harshness) applications, electrical products, and more..
Recent years, there has been a growing demand for VSAC ( Vehicle Semi-Anechoic Chamber ).
Sonora designs from scratch based on ISO standards or measurement methods specified by each user.
* Sound absorption layer on 5 faces (Walls, ceiling)
All components of the semi-anechoic chamber body are manufactured in Japan.
Products produced by the latest processing machines and skilled craftsmen ensure high precision.
The semi-anechoic chamber consists of steel sound insulation panels and frames as its basic structure.
Due to its compact and modular nature, on-site construction is easy, and dismantling and relocation are also possible.
The sound insulation panels and absorption wedges are original designs by Sonora.
Compared to other companies, they are high-performance yet thin, space-saving, and lightweight.
It is also competitively priced compared to other companies.
Various facilities such as wind tunnel testing machines, constant temperature and humidity equipment, equipment for transportation, and chassis dynamometers can be added.
We can propose sets with acoustic measurement instruments.
We handle measurement instruments from companies such as Brüel & Kjær, GRAS, Siemens, and others.
MODELS / PRICES
The specifications are just for reference, we customize from scratch.
There are 3 types of specifications. But basically, we’ll design from scratch, according to the size, measurement method and workability of the user’s acoustic measurement object. We can meet all kinds of requests, such as installing a crane, flattening the bottom of the door so that there is no step when carrying in, controlling temperature and humidity inside the chamber, and conducting a wind tunnel test.
