Anechoic Chambers, Acoustic Test Rooms & Reverberation Chamber

ISTIQ designs and builds specialized acoustic testing environments for clients who require controlled and reliable sound measurement conditions. Our solutions include Anechoic Chambers, Acoustic Test Rooms, and Reverberation Chambers, each serving a different purpose in acoustic testing, product development, research, quality control, and sound performance verification.

An Anechoic Chamber is designed to minimize sound reflections and create a low-background-noise environment for free-field acoustic measurement. It is suitable for testing products such as speakers, microphones, machinery, automotive components, appliances, electronic equipment, and other noise-emitting products that require accurate sound radiation data.

An Acoustic Test Room provides a controlled test environment for sound insulation, noise emission, insertion loss, equipment noise evaluation, or customized acoustic measurement requirements. The room can be designed based on the test method, internal noise criteria, background noise target, wall and ceiling construction, acoustic doors, ventilation system, penetrations, and equipment layout.

A Reverberation Chamber, on the other hand, is designed to create a highly reflective and diffuse sound field. It is commonly used for sound absorption testing, sound power level measurement, and evaluation of material acoustic performance. Unlike an anechoic chamber, where reflections are reduced, a reverberation chamber intentionally controls and maintains reflections for specific acoustic test purposes.

The success of any acoustic test facility depends on proper engineering design. Key considerations include room volume, background noise level, cut-off frequency, wedge or lining design, reverberation time, wall transmission loss, vibration isolation, floor construction, ventilation noise control, acoustic doors, cable penetrations, lighting, and compliance with the intended testing method.

ISTIQ’s experience in industrial noise control and architectural acoustics allows us to design practical acoustic test facilities that balance technical performance, buildability, maintenance access, and project budget. Whether the requirement is for product testing, research and development, laboratory use, factory quality control, university research, or industrial acoustic measurement, ISTIQ can provide a solution tailored to the required acoustic performance.
