ANECHOIC CHAMBER

Quite Room - NVH Test Chamber

Active Acoustics provided to Anechoic Chambers to provide design to the NVH Test Chamber in accordance with ISO 3744, ISO 3745 specifications.  At Active Acoustics, we provide great services from our expert team from designing, fabricating and installing an a semi / hemi anechoic chamber.

The NVH Test Chamber is a room designed in such a way that it has no resonance and therefore no resonance. Any sound emitted in the anechoic chamber is completely absorbed by the panel. Anechoic chamber is a special space with walls, ceilings and floors that absorb any kind of sound and electromagnetic waves. Not allowing the entry of noise from any external source makes the chamber completely untouched. Recycling time is very short for different audio frequencies.


Anechoic test chambers, hemi anechoic chamber, and quiet rooms and also noise test booth. They  are manufactured with modular, metal acoustical panels. This modular approach allows us the ability to construct acoustical rooms and chambers of various sizes  and for a multitude of applications. Each component is pre-engineered and design for easy site installation on site. Our NVH Test Chamber system/semi anechoic chamber can include a selection of openings that include; acoustical doors, windows, power and data cable, ventilation systems, etc 

We can provide totally integrated NVH Test Chamber systems and designs that include stringent requirements for such areas as; isolated floors, light and power connections, computer connections, ventilation, temperature and humidity control, instrumentation sleeves, control supports, working floors, and single and double sound doors.  Active Acoustic Engineers can also supply semi anechoic chamber, if necessary, a floating floor system to match the acoustical isolation properties of the chamber walls.  Host site conditions and the desired level of acoustical performance determine the floor design parameters.  Most systems will also provide interior and exterior finish options to suit your worksite.

Our experienced Acoustic Consultants can provide sound and noise level data specific to your site that will include recommendations for a Noise Test Chamber that will provide a viable, cost-effective solution to your noise problem .Get the best solutions from leading Anechoic chamber manufacturer in India.

1. Quiet Rooms

It provide a controlled acoustic environment to conduct noise evaluations on a product or specimen without the interference of outside noises and vibrations. Typically used on factory plant floors or in-plant labs, Active Acoustic Engineers Quiet Rooms are specifically engineered for high sound-transmission-loss and sound-absorption ratings which provide excellent noise reduction characteristics.

2. Hemi-Anechoic

Hemi anechoic chamber/ semi anechoic chambers provide an essentially free-field environment over a reflective plane (the floor) for the measurement of hemispherically radiated sound waves emanating from a sound source. Both types of chambers are well suited for rating sound output, and for providing directivity information.

3. NVH Test Chamber / Anechoic Chamber

provide an essentially a free-field environment for the measurement of spherically radiated sound waves emanating from a sound source. NVH Test Chamber are echo-free enclosures with a sound energy absorption level of 99% to 100%, or a reflected sound pressure level of 10% or less. The frequency at which the energy absorption drops below 99%, or the pressure reflection exceeds 10%, is known as the low-frequency cut-off. Sound absorption is obtained by lining the walls, ceilings, and floor with wedges or other sound absorbing elements, depending on performance level required and cut-off desired. we Are the leading Anechoic Chamber Manufacturer in India.

4. Performance

The NVH test chamber designed to achieve following conditions, Test Standards ISO-3744/3745.

Background Noise Level

  • Chamber has lower value of background noise level upto  15 dB(A) 

Free Field condition

  • The chamber absorb over 99.99% of incident acoustic energy above up-to 80 Hz 

Measuring Range

  • Cut off frequency: upto 80 Hz

NOTE: Background noise level and free field condition will be as per  design and test requirement criteria.
