Engine Noise Test Cells (ENTC’s) are typically environments for testing a standalone engine. Usually hemi-anechoic in design, an ENTC shares many characteristics with IAC VSAC chambers, but without a chassis dynamometer. ENTC’s typically have a cut-off frequency of 125Hz and feature a coupled exhaust extraction system, independent ventilation and cooling, a conditioned aspiration air intake set-up and the ability to accommodate either an AC or DC engine dynamometer.

AC Acoustics can provide a complete solution to acoustic engine testing facilities. Whether the requirement is just for an acoustic package including acoustic doors, windows and anechoic wedges or a turnkey solution, IAC Acoustics is unrivalled in our capability to deliver. A turnkey service is available on all IAC Acoustics ENTC\’s including ventilation system, exhaust extraction and lighting with the added peace of mind of having a single supplier responsible for the acoustic performance of the chamber.
