Introducing examples of anechoic box options (coupled type, change to anechoic box interior + change to sound insulation window)

AEB

Coupling type (half type)

A coupled anechoic box is an anechoic box split in half. Being approximately half the size, it is easier to transport and can be used in narrow entrances and narrow delivery routes. In addition, the weight of one anechoic box is reduced by half, so it can be used in situations where one anechoic box cannot be loaded due to elevator weight restrictions. Each half is transported to the planned installation location and docked using fasteners. The coupling does not affect sound insulation performance.

Anechoic box interior changes + sound insulation windows

The AST sound absorbing material inside the anechoic box has been changed to a wedge shape. When the object to be measured is set in the anechoic box and the door is closed, the inside of the anechoic box cannot be seen from outside. When measuring the acoustics of moving parts, etc., a sound-insulating window may be installed on the door.

This is a door that moves up and down using an air cylinder. We can design a variety of doors to suit your needs. We also manufacture doors that are electric rather than pneumatic.
