Question

An anechoic chamber is a room designed to

• A. Completely absorb reflections of either sound or electromagnetic waves
• B. Reflect sound or electromagnetic waves
• C. Absorb electromagnetic waves
• D. Transmit electromagnetic waves

Hint:

Anechoic chambers are designed to absorb sound and electromagnetic waves, providing a noise-free environment for testing and research.

Answer 1

The Correct Option is A

An anechoic chamber is a specially designed room that absorbs all sound reflections and electromagnetic waves to create an environment with no echoes or reverberations. The walls and ceiling are lined with sound-absorbing materials to prevent any sound from bouncing back.
These chambers are used for experiments and testing in acoustics and electromagnetic wave studies, where the absence of any external noise or reflections is required.
The chamber does not reflect sound or electromagnetic waves, nor does it transmit them. Its primary function is to absorb them completely.
