Envirotech Systems Pvt. Ltd. - Application - Anechoic Test Facilities
ANECHOIC TEST FACILITIES  


We design Anechoic test chamber for the determination of sound power output of noise sources, transmission loss of partitions, insertion loss of silencers, response characteristics of microphones, and random incidence absorption coefficients of materials. They are also used for high-intensity noise-level fatigue testing of aircraft, space vehicles, and other equipment.

These test facilities are designed not only to fully satisfy reverberation requirements, but also meet specific interior acoustic sound levels and other environmental requirements.  In addition, we offer the entire range of tailored products to provide suitable working spaces, sizes and types of doors, lighting and electrical systems, climate controls, as well as RF shielding appropriate to the work intended.

All these elements are assembled within an engineered modular structural framework, to assure the overall integrity.

ROADS AND HIGHWAYS  


Envirotech’s Absorptive noise barrier walls are the single most effective mitigation tool for reducing unwanted road and traffic noise.

Noise generated by road and highway traffic is fast becoming one of the most contentious environmental problems worldwide. As urban and residential sprawl encounters heavier and heavier traffic loads on nearby roads and highways, residents and communities are demanding better noise abatement from their local officials and DOT's. ESPL’s Absorptive Noise Barriers have proven to be very effective and durable for over 13 years.

The ESPL Highway Sound Barrier System effectively provides road noise reduction for:

  • »   Truck Noise
  • »  Highway Noise
  • »  Pavement Noise
  • »  Toll Road Noise

While reflective products like concrete have been the traditional material for highway sound/noise barrier walls, the advanced absorptive materials found in the Barrier System present a much more effective noise abatement option. Reflective products like concrete or brick simply bounce sound waves in different directions. The LSE System actually "kills" the sound waves that hit it... significantly reducing overall noise.

If you are facing problems caused by traffic and road noise, Sound Fighter Systems can immediately provide an effective abatement solution for you!
