The noise test booth is used for check the noise level. It is a quiet room and is used for a number of different purposes as well.The main functionality of a noise control booth is to eliminate the shop floor noise. The isolation of the noise test booth with acoustic material all around prevents the floor noise from penetrating the enclosure.

The primary features of the noise test booth are:

•    Reliability: The booth is totally quiet and it has been built in a manner so as to not allow any noise to penetrate.
•    Performance: The noise test booth will continue to provide optimal performance
•    Noiseless operation: The functioning of the noise test booth is absolutely noiseless.
•    Low maintenance: The noise test booth is very easy to maintain and does not require any kind of service.
•    Internal lighting: The noise test booth is a complete unit and comes fully fitted with an internal lighting system.
•    Automatic door: The acoustic door of the noise test booth closes automatically to ensure that it is sealed shut and there is no chance of noise leakage.
•    Ventilation system: The noise test booth has been designed with air vents to ensure that there is air circulation inside the unit. The air vents are acoustically treated.

Areas of application of a noise test booth
The noise test booth is used in many areas such as the manufacturing industries to test horns, motors, air conditioners, speakers etc. Noise test booths are also use in the automotive sector to check reverberation and engine noise.

Noise Test Booths being absolutely sound proof and quiet rooms are also used for medical testing as portable laboratories. The chamber also serves well as a research and development lab for highly sensitive research which can be affected by noise.

The NVH Test Chambersare usually custom designed according to the client’s specific need. They are manufactured with the dimensions and for the sound level required. The NVH test chamber focuses on the Noise, Vibration & Harshness of the sound. This analysis is performed by our experienced and qualified acoustic engineers who measure the noise levels. The impact of the sound and vibration on the environment is evaluated and we advise our client regarding the appropriate measures. Noise mapping, the structural dynamics and monitoring aids in identifying the source of the noise helps to ascertain the control measure that need to be enforced.

Features of NVH Test Chamber

•    Easy to relocate: The portability feature of the NVH test chamber makes it easy to relocate.
•    Optimal isolation: Sound isolation can be achieved to a maximum degree in the NVH Test Chamber
•    Maximum strength: The durability of the test chamber comes from the material used for manufacture.

APPLICATIONS FOR NVH TEST CHAMBERS:
The purpose of the NVH Test Chamber is to reduce shop floor noise. The NVH Test chamber can be used for internal noise generation as well as keeping out external noise. Muffling noise is effectively carried out by using the NVH Test Chamber. Other areas of application of the NVH test chamber are for recording studios when bands are performing or voice overs are being recorded or if there is a broadcast taking place. Events such as trade shows, private conferences, language classes, hearing tests and karaoke also use the NVH test chamber. Sound testing for loud machines and industrial projects use the NVH test chamber.

Our Assembly Line Noise Test Chamber has been scientifically designed with precise precision to provide specific data. It is used extensively in the automotive industry and in other motor manufacturing industries. It is made of an acoustic dampening base material providing both on line and off line testing facilities.

As the name suggest this noise test chamber has been specially designed to use in the manufacture and assembly of products including air conditioners and refrigerators among many other heavy machines. The assembly line noise test chamber is used for identifying defects in the machine parts using sound testing.

The Assembly line Noise test chamber is now being extensively used in the electronic industry for testing mobiles, tablets and blue tooth speakers. The Assembly line noise test chamber can be configured according to the specific requirement providing a flexible platform for the testing. It enables an ambient atmosphere for accurate sound testing with reduced reflective surfaces.

Features of Assembly Line Noise Test Booth
Our assembly line noise test booths are built with a robust design for superior performance and with all the required features.

•    Automatic window: The sound proof window remains automatically closed during equipment sound testing. The opening and closing of the windows is directly linked with the functioning of the test chamber. The acoustic performance of the window is 40 dB(A) at an ambient of 75 dB(A).
•    Conveyor belt: The Assembly line noise test chamber has a conveyor belt that allows the entry and exit of the products to the test chamber. The conveyor has automatic sensors to stop and start. The approximate productivity of the Assembly line noise test chamber is measured at 2200 pieces a day.
•    Hinge type opening: The opening of the assembly line noise test booth has pneumatic cylinders to control the opening. The entry and exit window have a lever that is used to control it. The sound control performance of this opening is 35 dB(A) with an ambient of 85 dB(A).

Anechoic chamber is a room that has been designed in a manner that it has no reverberation and hence no echo. Any sound emitted in the anechoic chamber is totally absorbed by the panels. The Anechoic chamber is a special place with walls, ceiling and flooring that absorb any kind sound and electromagnetic waves. The chamber is totally insulated not allowing the penetration of noise from any external sources. The reverberation time is very low for various audio frequencies in the Anechoic Chamber.

Design of Anechoic Chamber
The anechoic chamber is usually constructed of cement and bricks. The interiors of the anechoic chamber have been designed to provide total sound insulation. The internal surfaces are has PU wedges foam lining which provides the highest degree of sound absorption.The floor of the anechoic chamber is lined with floor wedges for acoustic absorption.

Sound absorption parameters of Anechoic Chamber
In the Anechoic Chamber the effectiveness of sound and electromagnetic waves absorption is measured in decibel rejection. This is the ratio of direct sound to reflected sound, inside the anechoic chamber. The Envirotech Anechoic Chamber offers a 80 dB rejection from 20 KHz to 80 Hz.

Industrial Application of Anechoic Chamber
The Anechoic chamber is ultra-silent. It is used in areas that require high precision sound measurement which helps to augment performance and design of the equipment. Anechoic chambers are especially useful for electronic devices related to sound like speakers, microphones, cell phones and other such devices.

Features of Anechoic Chamber

•    Soundproof: The Anechoic chamber is 100% sound proof inside with non-reflective surfaces.
•    Low Maintenance: The design and construction of the Anechoic Chamber is such that it does not require much maintenance.
•    Sturdy: The Anechoic chamber has a very sturdy construction which is weather resistant, impact and damage resistant, fire retardant and abuse resistant.
