Noise Test Enclosure

Noise test enclosures sit directly on or beside a production line, enabling every unit to be screened for abnormal noise signatures without disrupting throughput. Unlike dedicated test chambers, these enclosures are optimised for cycle time and repeatability rather than free-field conditions — making them the standard solution for motor, pump, home appliance, and power tool QC.

HEMU Acoustics noise test enclosures use a modular panel system with click-locking steel frames. Standard panels achieve 20–35 dB insertion loss; high-performance double-skin panels achieve up to 40 dB. Hinged access panels and removable sections are designed into the enclosure for routine maintenance without full dismantling.

The enclosure is sized to clear the machine by 150–300 mm on all sides, enabling natural convection cooling for most applications. For high-heat applications, ventilation packages with acoustic attenuators are integrated into the enclosure design. All cable and hose penetrations are sealed with acoustic putty collars.

ATEX-certified variants are available for machines in hazardous areas (Zone 1 and Zone 2). Panels are manufactured in chemical-resistant powder-coat finish as standard, with stainless steel available for food, pharmaceutical, and marine environments.
