The Modular Fully Anechoic Chamber is used for measuring sound power for home appliances, small drive components, and for electrical acoustics measurements.
Sonora designs from scratch based on ISO standards or measurement methods determined by each user.
* Sound absorption layer on 6 faces (Floor, walls, ceiling)
All components of Sonora’s anechoic chamber are manufactured in Japan.
Products manufactured by the latest processing machines and craftsmen ensure high precision
The anechoic chamber consists of steel sound insulation panels and frames as its basic structure.
Its compact and modular design allows for easy on-site installation, dismantlement, and relocation.
The sound insulation panels and absorption wedges are original Sonora designs.
Compared to other companies, they offer high performance while being thin, space-saving and lightweight.
It is lower priced compared to other companies.
Various facilities such as wind tunnel test equipment, constant temperature and humidity facilities, and handling equipment can be additionally installed.
We can also propose sets with acoustic measuring instruments.
We handle measuring instruments from companies such as Bruel & Kjar, 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 in an anechoic room, and conducting a wind tunnel test.
