Compact Coupling-Type Anechoic Box for a Major Electronics Manufacturer [USA]
AEB
We delivered a compact coupling-type anechoic box for a major electronics manufacturer.
This system was designed to achieve both high sound insulation performance and internal sound absorption performance within a limited installation space, providing a quiet environment suitable for various acoustic evaluations and tests.
The interior is equipped with a sound-absorbing layer, while the enclosure adopts a multilayer sound-insulating panel structure. In addition, the unit includes wiring ports, an airtight handle, removable eyebolts, and eyebolts for microphone installation, making it easier to set up test specimens and measurement systems.
The base section is also equipped with vibration isolators, adjusters, and casters, achieving both installation stability and mobility. Its modular structure also allows flexible response to transportation and installation constraints.
