Manual Acoustic measurements anechoic chamber
The anechoic chamber is immensely quiet and with no room reflections. This makes it ideal for testing very quiet products or hearing very quiet sounds. This is a room which is acoustically like being high above the ground in the open air because there are no reflections from the walls, floor or ceiling. This means it is ideal for testing the response of loudspeakers or microphones because the room doesn’t affect the measurements. It is also the best place for virtual acoustics – generating auralisations of concert halls, city streets and other spaces.
This acoustic chamber is built in such a way to minimise the level
of acoustic background and acoustic waves reflected from the walls
and limit the external noise. Sounds from the outside are strongly
suppressed due to the walls’ acoustic insulation and the materials
used. Internal surfaces are covered in material with strong
sound-absorbing properties; the chamber is lined with “porfles”
tiles. Lighting and electricity, together with a table allowing set
up of the measuring apparatus are located inside the chamber.

There are three main types of acoustic test chambers:
- Hemi-Anechoic Rooms. In a hemi-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.
