Isolated Chamber For Electromagnatic Acoustic Measurements
An anechoic chamber is used for either acoustic measurements or electromagnetic / RF measurements. Acoustic anechoic chambers do not allow reflection of sound waves inside the chamber and do not allow sound waves coming from outside. Electromagnetic/ RF anechoic chambers do not allow the reflection of electromagnetic waves inside the chamber and do not allow electromagnetic waves coming from outside.
- Electromagnetic pulse protection EMPP shielding
- TEMPEST (secure communications) shielding
- Architectural shielding systems
- MRI shielding
Why anechoic chamber is used?
The main purpose is to create a reflection-free and noise-free test
and measurement environment. Performing tests inside an anechoic
chamber give you much more reliable and accurate results when
compared to testing outside.
Acoustic and electromagnetic measurements are the measurements of the strengths of frequencies. But, when performing these measurements, how will you avoid reflections from other objects, interfering signals or noise? You have to use special materials that absorbs unwanted signals and shielding that prevents interfering signals or noise.
- Top and outer dimensions: 780(W)*780(W)*600(H) mm
- Upper inner size: 400(W)*400(W)*4400(H) mm
There are three main types of acoustic test chambers:
- Hemi-Anechoic Rooms. In a semi-anechoic chamber, only part of the room receives acoustical treatment. For example, the walls and ceiling may be designed to absorb sound energy, but not the floors. Hemi-anechoic rooms are generally used for automobiles, construction equipment, heavy appliances (e.g., refrigerators, washing machines), and other items that operate directly on sound-reflective surfaces such as floors and roads.
- Full Anechoic Chambers. This type of chamber is designed to absorb up to 100% of the sound energy within its walls. Its surfaces are covered with anechoic material and its floor is designed to support heavy test specimens. Full anechoic chambers are often used for speakers, microphones, and other equipment that requires reverberation to be kept at a minimum.
- Pass/Fail Chambers. As its name suggests, this chamber is designed to test whether a specimen meets the acceptable standards of acoustic quality. Pass/fail chambers accommodate devices like mobile phones, computer equipment, and others that don’t need to be tested under hemi-anechoic or full anechoic conditions.
