[Estech Corporation] Modular Semi-Anechoic Chamber
MSAC / VSAC
This is a semi-anechoic chamber designed for testing purposes for Esutek, located in Yokohama, Kanagawa Prefecture, Japan.
Primarily used for vehicle acoustics measurements.
- Soundproof panels: Steel soundproof panels t150
- Absorption wedges: AS absorption wedges t500
- Soundproof door (integrated with absorption unit): Effective W3,800×H3,500
In the center of the room is a reference plate, and towards the back is an exhaust emission device for automotive exhaust mufflers. The emission device utilizes flexible ducting, allowing it to be moved to the position of mufflers for various car models.
For ventilation and air conditioning, all components are designed for noise reduction. The system includes silencers for air conditioning, ventilation, and exhaust, with provisions for air circulation both inside and outside the semi-anechoic chamber. This allows for acoustic measurements even when each ventilation system is operational.
