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.
