An anechoic chamber is a shielded room that attenuates waves. An anechoic chamber has specialized walls that absorb and reflect sound waves and electromagnetic radiation. You can use anechoic chambers for testing in various industries such as automotive, aircraft and electronics.

Educational institutions, universities and research centers also use these testing chambers for research work. You can review different anechoic chamber brands suitable for conducting various tests such as acoustic testing, electromagnetic interference (EMI) testing, radio frequency (RF) interference testing and electromagnetic compatibility (EMC) testing.

Some of the important parameters you must consider before purchasing an anechoic chamber are:

1. Dimensions of the test component
2. Type of the testing setup
3. Ambient noise level and interference
4. Structural details such as supports and space available for installing an anechoic chamber

Compare the anechoic chamber price when buying for acoustic testing

For soundproof testing or noise isolation purpose, you must buy an acoustic anechoic chamber. For selecting an acoustic anechoic chamber, the price of the walls or panels is a significant parameter. These panels absorb maximum sound waves.

I recommend: Despatch Industries offers acoustic chambers suitable for the testing of automotive industry products. Memtech is a provider of noise reduction and isolation equipments including acoustic chambers. You can also buy a chamber from Phoenix-E, a reputable anechoic chamber manufacturer.

Buy an anechoic chamber suitable for RF interference testing

Radio frequency testing is one of the important analysis phases for electronic products. As high amplitude RF can be hazardous to human operators, ensure automatic controls for anechoic chambers that use it.

I recommend: Cuming-Lehman Chambers, a specialist manufacturer of RF shielded anechoic chambers, provides chambers for analysis of aircraft products. MAXSYS Technologies is another manufacturer of manual, semi-automated and fully automated RF test fixtures and shielded chambers. You can also check anechoic chambers by DJM Electronics, a provider of RF shielded chambers.

Buy an anechoic chamber for EMC testing

EMC testing anechoic chambers are useful for testing an electronic device or system to reduce its electromagnetic interference. The sample device must work efficiently without error in stimulated electromagnetic fields in the anechoic chamber.

I recommend: TDK is one of the leading manufacturers of anechoic chambers specially designed for EMC testing. Emerson & Cuming Microwave Products supplies anechoic chambers useful for the testing of automotive, medical and aerospace products. Additionally, ORBIT/FR and Tempest develop and manufacture EMC testing anechoic chambers.

Buy standard anechoic chamber parts

You must buy anechoic chamber parts from reputable suppliers for efficient functioning of your new as well as used, anechoic chamber; cost of parts will vary. Also consider refurbished anechoic chamber parts.

I recommend: Cuming Microwave supplies RF absorbers and ferrite tiles for EMC chambers. Isotech and IES2000 offer various anechoic parts such as anechoic foam and an acoustic curtain. Eckel Industries, a reputable manufacturer of portable anechoic chambers, also supplies acoustic and modular panels.

Tips & Tactics

Helpful advice for making the most of this Guide

• •  Install smoke detectors and fire fighting systems to ensure safe operation of anechoic chambers.
• •  Inquire about the testing capability, cost and other specifications of an anechoic chamber before you place an order with the manufacturer.
