Hemi Anechoic Acoustic Chamber
A constructed hemi-anechoic chamber serves as an environment for measuring noise, particularly for assessing the acoustic power levels of equipment and machinery. Its assembled using Sola metal panels & frames. The interior is made up of non-combustible sound-absorbing wedges. this hemi anechoic chamber allows for easy disassembly and transportation since it doesn’t involve concrete walls. We offer the flexibility to create customized structures tailored to specific measurement purposes and layouts.
