Rental of anechoic chambers, semi-anechoic chambers, and reverberation chambers.

We have an anechoic chamber with top-level performance in Japan.
Our audio and vibration specialists will assist you.
In addition to renting out our acoustic laboratory, we also offer equipment rentals and commissioned measurement services by our expert staff, according to your needs.

Application example: Measurement of characteristics of microphones/speakers, etc.
Recording of dry source sounds, sound source detection using the SI method, etc.
