Research and Development has enabled IAC to maintain its position as a leader in the Noise Control Industry for almost a half century. Our wide range of products and a strong tradition of custom engineering have demanded a high level of scientific and technological expertise in acoustics, aerodynamics, materials and manufacturing processes.

Our Aero-Acoustic Laboratories maintain a rigorous standard of quality in performing independent tests of our products. Recognized by the National Institute of Standards and Technology under the National Voluntary Laboratory Accreditation Program (NVLAP) for acoustical testing services, the lab serves to underpin many of the Company's activities. The acoustic test facilities include a 10,000 cubic foot reverberation room, acoustic wind tunnel and an anechoic chamber. Mechanical and structural testing is performed on a variety of special purpose test fixtures and a high pressure blow-down rig provides for aerodynamic modeling of heavy duty silencers and jet engine test cells.

Innovative thinking, backed by rigorous testing and experimentation has enabled IAC to be first in the field with many products and materials for sound control ranging from duct silencers to sound proof doors, recording studios, anechoic test chambers and aircraft run-up pens. One example of IAC's many patented products is the packless duct silencer for controlling air conditioning system noise. This, together with our new, all metal, fiber-free acoustic ceiling tile, provides a total solution to the problem of maintaining good indoor air quality in hospitals, food processing plants and semi-conductor "clean rooms".

IAC's Research and Development team continues to study developing technologies relating to acoustics in communications, security systems, entertainment, aviation and architecture. Our aim is to maintain the effectiveness of our products in meeting the needs of our customers and to apply state-of-the-art solutions to "making the world a quieter place".
