Acoustic Panel Enclosures for Industrial Process and Environmental Systems

Featuring NOISEBLOCK™ Type HTL and STL Acoustic Panels

Gas Compressor Enclosure

Description

Claims for hearing damage, safety and economic requirements make a noise reduction program essential for many industries. In the past, many manufacturing facilities were regulated by a government agency such as OSHA, but today insurance companies who seek to keep claims for hearing damage to a minimum for the facilities they insure drive the vast majority of noise regulation.

To meet these requirements and to help solve many in-plant noise problems, Kinetics Noise Control manufactures a complete line of acoustical panels which can be quickly and easily assembled to provide complete or partial enclosures for noisy equipment or to provide a quiet office in a manufacturing area. Acoustic panel enclosures are designed to provide optimum noise control through sound absorption and sound transmission loss.

Kinetics acoustic enclosures are designed and manufactured using our standard NOISEBLOCK™ type "STL & HTL", tongue and groove panels. Acoustic panels are fabricated of solid steel outer skin, and solid or perforated steel inner skin. Panels are stiffened with pre-formed steel channels. Acoustic grade fill is packed under compression. Sound enclosures are available with doors, access panels, removable panels and ventilation packages. Materials of construction include: galvanized steel type G90, stainless steel, or aluminum.

Kinetics offers complete design and engineering assistance including layout as well as providing acoustical, structural and ventilation requirements.

NOISEBLOCK™ Type STL Acoustic Panels

Standard Kinetics NOISEBLOCK™ STL acoustic panels are fabricated with outer skins of 18 gauge galvanized steel and inner skins of 22 gauge perforated galvanized steel. Acoustic panels are stiffened with 18 gauge steel channels. Sound absorption is provided by 2.5 to 6 pcf fiberglass or mineral wool depending on the application. Standard panels are nominally 4" thick, but optional 2" and 6" panels are available to meet special requirements. Two-inch acoustic panels are rated at STC 37 and NRC .95, 4" acoustic panels are rated at STC 40 and NRC 1.00.

NOISEBLOCK™ Type HTL Acoustic Panels

Kinetics NOISEBLOCK™ HTL acoustic panels are designed for applications where more transmission loss is required. The HTL acoustic panels are fabricated of a 16 gauge outer skin, a 22 gauge perforated inner skin, 18 gauge stiffener channels and a high mass septum. The 4" thick HTL acoustic panels have an STC of 48 and a NRC of 1.00.
