Leading Anechoic Chambers Manufacturers & Suppliers in India, Mini/ Semi/ Hemi/ Full Anechoic Chamber is a room designed to completely absorb reflections of sound. for Noise, Vibration & Harshness (NVH) Test Facilities From Ecotone Systems

We are Ecotone Systems , one of India’s most reliable and largest Designers, Developers & Manufacturers of Anechoic Chambers for Noise, Vibration & Harshness (NVH) Test Facilities.

It is a great challenge to combat the noise transmission at commercial and industrial places. An anechoic chamber is the only viable solution to have the balance in the most integrated manner.At Ecotone we completely understand the importance of anechoic chamber and offer great services.Right from designing, fabricating and installing an anechoic chamber we are the most trusted and reliable developers, designers and suppliers in the field of an anechoic chamber. Our aim to design the chambers for the industries, large scale manufacturing units, malls, auditoriums, lecture halls, gyms, indoor stadium etc. With the latest technology and advanced resources, our well experienced and dedicated team members work in close coordination with the clients to bring up an integrated and personalized anechoic chamber.Our developers work to execute high accuracy measurements thereby ensuring clean and well-balanced calibrations. Our anechoic chamber construction offers a great amount of advantage in such a manner that they are able to absorb a large amount of exterior noise. Quite easily the undesired resonances and noise transmissions can be identified and the clutter is eliminated. It can easily be able to exclude the exterior noise with great ease and convenience.

In order to remove the sound reflections from the walls of the chamber, our technicians and designers cover each and every surface with the help of absorbing materials. The interior of the chamber is designed with the help of foam wedges which will very easily be able to absorb the sound.

The Ecotone designed chambers have features of that of sound attenuating like the proper ventilation facilities, temperature and the humidity measurement, isolated and working floors, instrumentation sleeves etc. Each of the chambers, is inclusive of comprehensive acoustical testing and evaluation facility to ensure proper sound management.


ECOTONE™ chambers are constructed with noise attenuating outer structures of modular panels and have all interior surfaces lined with PU wedges Foam or Metallic Wedge of Plain absorbing surfaces. This has working floors constructed with grating floor sections to support heavy test specimens above the floor wedges. This is basically designed to suppress the internal sound reflections and used for acoustical measurements.The effectiveness of an anechoic chamber is measured in dB of rejection, which is the ratio of direct sound to reflected sound inside the room. Our designed anechoic chamber provides better than 80dB rejection from 20 kHz down to 80H.


Ecotone Systems design anechoic chambers for the applications that require precision-level acoustic measurements need to optimize product design and performance of Loudspeakers, Microphones , Cell Phones , Information Technology Equipment , Automobile Components & Home Appliances.

Semi Anechoic Chamber

A room which creates free field conditions but above a reflective plane. Above a certain frequency all sound waves that hit the walls or ceiling of the chamber will be absorbed.This type of chamber is normally used in vehicle testing with a rolling round so that the vehicle may be driven. The semi-anechoic chamber then forms a controlled environment with the surrounding acoustic conditions behaving as a sterile version of the real world. In this way accurate measurements of the sound inside and outside the vehicle can be made under operating conditions.

Hemi Anechoic Chamber

HEMI-ANECHOIC CHAMBERS have acoustical treatment on the walls and ceiling only and feature hard floors with no acoustical treatment. The solid floor of the hemi-anechoic chamber is common for testing large and heavy equipment such as automobiles, construction equipment, ATV’s or white goods and appliances such as refrigerators, washers and dryers, where the normal mode of operation is over a reflective plane such as a floor or hard road surface.Both Hemi-anechoic and Full anechoic chambers can be used in combination with reverberation rooms for transmission loss studies for car body panels and even the noise attenuating characteristics of aircraft fuselage construction.

Mini Anechoic Chamber

  • By aligning automatic measuring system, you can save a time margin on measuring.
  • You can measure as much as you like by using the mini anechoic chamber at your location.That gives you a time margin in measuring to clear standards and save a developing cost after all.
  • This mini anechoic chamber provides you a lot of values as much as a low cost, a short-termed construction, no more large space required and a convenience in measurements as just you are.

Portable Anechoic Chamber

ECOTONE™ Portable Anechoic Chamber are preferred by a communications manufacturer to perform acoustic tests on digital assemblies being developed by their acoustics laboratory. This all steel panel construction using the unique cam locking hardware allows this unit to be manufactured and shipped in 3 sections and quickly assembles on the lab floor.
The outside dimensions assembled are 2337 W x 2337 D x 2413 H ( 92″ W x 92″ D x 95″ H) and the free field area is mm 1499 W x 1499 D x 1499 H (59″ W x 59″ D x 59″ H). Provision was made to place a removable table in the interior to set up and perform experiments. The wedge units are Standard EW wedges, 250 Hz. Cut off frequency. Lighting, cable access ports, vibration isolation and an interior door safety release are included with the unit.
