QuietStar is a UK anechoic chambers supplier. Anechoic chambers are unique acoustic testing enclosures used for research and development, enabling engineers and scientists to take precise acoustic measurements. Full anechoic (meaning no echo) rooms are lined on all six internal faces with absorbent material to completely absorb sound reflections in all directions. The lack of reflective surfaces in effect offers a complete free-field sphere around the object being evaluated meaning precise acoustic measurements can be taken from all directions. This is particularly important when trying to pinpoint sources of noise from a test subject.
At QuietStar we use wedges in the construction of our anechoic chambers, as these have been proven to absorb sound waves better than flat panels. The more absorption, the better the results for any research and development. Depending on what is being examined in the laboratory, access to the anechoic room may be via an acoustically transparent floor, or hung from wires / harness points located on the inner surfaces. For heavy or bulky items, our chambers can also be designed with a structural steel meshed floor to allow items to be manoeuvred into place with ease. QuietStar has even designed chambers with mechanically retractable floors which allow people to walk around the chamber and set up acoustic experiments and then once they are outside, simply retract the floor to maintain the absorbent finish.
