KOCH Acoustical Noise Enclosures feature significant reduction and absorption characteristics as a result of KOCH’s unique pre-fabricated modular acoustical panel construction. Interlocking tongue and groove seams eliminate separate panel connectors and “H” joiners, making our modular system quick and simple to assemble. Our optional baked-on powder coat finish is beyond comparison!

Our modular acoustical enclosure system is easily configured around new and existing equipment using standard components and is easily set up without special tools. Accessories include acoustical doors, windows, ventilation systems, air conditioning, lighting, receptacles and penetrations for piping and electrical.

Through decades of experience and product development, KOCH acoustical noise enclosures exceed customer expectations in all aspects including sound attenuation, reverberation, appearance, cleanability, abuse resistance, cost, and ease of installation.
