Engineers use anechoic chambers
to test these devices too.
New product categories such as wireless appliances, teller machines, and automotive devices sometimes require a larger quiet zone and necessitate either an oversized anechoic chamber
or a reverberation chamber to test to the certification requirements.
In addition, at 6 GHz, less than -20dB resulted for 5 mm of RHC clad thickness, which are the minimum requirement for commercial anechoic chambers
according to CISPR11.
Measurements are first performed in the anechoic chamber
to eliminate the majority of the environment multipath reflections (excepting those relative to the floor), and then repeated in the Body-Centric Wireless Sensor Lab at Queen Mary, University of London (sketched in Fig.
To validate the previous numerical analyses, radar experimental measurements have been carried out in an anechoic chamber
for the both configuration (monostatic and bistatic).
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.
To respond to this demand, TDK will construct a state-of-the-art, cutting-edge anechoic chamber
at the Technical Center to measure and evaluate electromagnetic waves during new product development and to propose EMC countermeasure technologies and countermeasure products as well as reinforce the EMC solution business by analyzing customer products.

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.
The testing started inside the anechoic chamber
with antenna-pattern measurements.
-- Measures the amount and quality of acoustic output to improve acoustic performance.
