Anechoic chambers are used to evaluate the electromagnetic compatibility (EMC) of military and commercially-available, electronic equipment.
A free space measurement in the anechoic chamber was performed to verify the propagation delay between the two antennas at 1 meter distance and the noise floor, observed as more than 40 dB below the peak power.
"Once we figure out what tape to use, we take it off the tester, put the tape in the radome and then hang it in the anechoic chamber and let it go through all of the tests."
Characteristics as an EMC anechoic chamber (site attenuation* characteristics: +/- 1.5 dB or less; 30 MHz - 1 GHz) are at the world's highest levels, making possible highly precise measurements and assessments.
Information from Daisy quacking in the echoless anechoic chamber was used to produce a computer model of what she would sound like flying past a cliff face.
For example, a reverberant room is used to measure sound power emitted by an appliance, and an anechoic chamber to chase down the sources of those sounds.
Accoustical chamber tests of sound transmission characteristics of the EPDM rubber and the sound attenuating elastomeric alloy grades have been conducted using an anechoic chamber. The apparatus consisted of a white noise source connected to a tube shaped sample of the elastomer.
