Envirotech Anechoic Chamber Manufacturer is useful in automobile industries. They are constructed to attenuate noise with their outer structures fabricated with modular panels. The inner surfaces are lined with metallic wedge/ PU wedge/ plain Semi Anechoic Chamber to act as absorbing surfaces. A fully functional anechoic chamber has functional floors that have grating to support any heavy test subject. They are designed to suppress all internal sounds and are used to measure acoustical severity.
Semi Anechoic Chamber is a room with walls, a ceiling, and a floor that are completely reflective so that the chamber can be used to perform tests on the acoustics of a space. These Semi Anechoic Chambers are made of high-quality materials and are specifically designed to work with sound waves in a specific area. They come in different sizes and have been made to work with all types.
Envirotech Mini/Portable Anechoic Chamber is preferred by a communications manufacturer to perform acoustic tests on digital assemblies being developed by their acoustics laboratory. The external dimensions of a standard portable anechoic chamber are W – 2337 mm x D – 2337 mm x H – 2413 mm (W – 92″ x D – 92″ x H – 95″) and the dimensions of the internal free field area are W – 1499 mm x D – 1499 mm x H – 1499 mm (W – 59″ x D – 59″ x H – 59″).
Envirotech provides NVH Test Chamber and vibration analysis. Our engineers working in these fields measure sound and vibration levels to determine whether the engineering redesign or optimization is necessary to meet customer expectations and requirements. The evaluation of sound and vibration, in terms of their impact on the consumer and the surroundings, includes not only the objective measurement of noise and vibration but also the subjective impact.
We offer customized Audiometric Chamber booth designs available in different sizes and configurations. Audiometric Screening Booth provides a self-contained environment for hearing conservation programs. A large side entry door allows ease of access to persons of all ages. The Audiometric Chamber is used by audiologists and speech-language pathologists to conduct error-free hearing tests. The chamber is used to conduct a range of tests including pure-tone, speech, and audiometry tests.
The airborne sound insulation performance requirements of internal partitions are closely linked to intrusive noise criteria. However, another very important factor is “privacy”, that is, the extent to which conversations and activities in one area are audible in an adjacent area. The recommended privacy factor for Audiometric Screening Booths is 80, where 75-80 is audible but not intelligible and >80 is inaudible.
