Custom-Engineered Acoustic Enclosure Systems
KINETICS® NOISEBLOCK™ Acoustic Enclosures are engineered noise control systems manufactured using double-walled acoustic panels in various material types, thicknesses, and finishes. They are designed for indoor and outdoor noise applications where equipment sound must be controlled without restricting maintenance access, personnel access, or required ventilation. These enclosures are commonly used for manufacturing processes, generators, fans, pumps, chillers, blowers, compressors, and other mechanical or industrial noise sources.
Noise Reduction Through Absorption and Transmission Loss
NOISEBLOCK™ Acoustic Enclosures provide a composite acoustic solution using sound absorption to reduce internal reverberant noise and transmission loss to block sound from escaping the enclosure. Typical noise reductions are 20–35 dBA, with special custom systems available for higher levels of noise reduction using heavier panel shells, thicker panels, or enclosure-within-enclosure configurations.
Suitable for HVAC, Industrial, and Environmental Noise Control
For commercial building projects, NOISEBLOCK™ acoustic enclosures support noise control around heating, ventilation, and air-conditioning systems, including built-up and custom air handlers, fan enclosures, HVAC mixing plenums, supply and return plenums, outside air plenums, double-wall panel duct, and mechanical equipment. In industrial facilities, they help control noise from generators, compressors, manufacturing equipment, test chambers, vacuum blowers, positive displacement blowers, paint booths, and in-plant offices.
Outdoor Acoustic Enclosure Design
For environmental noise control, partial or complete NOISEBLOCK™ Acoustic Enclosures can be used around outdoor equipment such as air-cooled chillers, cooling towers, LNG terminal process equipment, wastewater treatment plant process blowers, generators, fans, and blowers. Outdoor systems can incorporate design considerations such as wind loading, weather protection, roof design to avoid water pooling, waterproofing, and suitable material selection for exposed environments.
Panel Construction and Access Options
Standard NOISEBLOCK™ acoustic panels are available in STL and HTL configurations depending on the required level of noise control. STL panels are used for general acoustic enclosure applications, while HTL panels are designed for higher transmission loss requirements. Available materials include galvanized steel, G90 galvanized steel, mill phosphatized galvanized steel, stainless steel Types 304 and 316, aluminum, and aluminized steel. Factory-applied powder-coat finishes are also available as an option.
Accessories for Functional Equipment Enclosures
NOISEBLOCK™ Acoustic Enclosures can be supplied with silenced ventilation systems, fixed-blade acoustic louvers, observation windows, single or double leaf access doors, removable wall and roof access panels, lifting lugs, and flashing where required. These accessories allow the enclosure to provide acoustic performance while supporting equipment cooling, inspection, maintenance, service, and safe access.
The mitigation of noise from heating and cooling systems in modern commercial projects is an important aspect in any building design. Kinetics Noise Control engineers and manufactures complete pressurized plenum enclosures. NOISEBLOCK™ pressurized plenums are designed to provide effective noise control, structural integrity, along with full access for maintenance and inspection.
Worker safety has taken on increasing importance for industrial facilities, and as such, noise reduction initiatives have become an essential goal of the industry. NOISEBLOCK™ acoustic enclosures are a key design element in bringing industrial, process and manufacturing facilities to safer noise levels and to help make a better work environment for all involved.
To mitigate outside noise sources a partial or complete NOISEBLOCK™ acoustic enclosures can be used. Kinetics Noise Control engineers their acoustic enclosures with special design considerations for outdoor use, such as wind and snow loading, weather protection, proper roof design to avoid water pooling, waterproofing, and the use of special materials.
Achievable Noise Reduction
NOISEBLOCK™ acoustic enclosures offer typical noise reductions of 20-35 dBA. Special custom systems incorporating heavier (thicker gage) panel shell, thicker panels or an enclosure within an enclosure are available to achieve higher levels of noise reduction.
Type STL acoustic panels are fabricated of various thicknesses and materials depending on the level of noise control required for a particular application. Standard KINETICS NOISEBLOCK™ type STL panels are fabricated with an outer solid shell of 18 gage and inner perforated shell of 22 gage steel. Panels are stiffened with 18 gage internal channels and edge rails. The acoustic grade fill is 2.5 to 6 pcf long strand fiberglass or mineral wool, depending on the application, are inert, mildew resistant, vermin proof and incombustible. Standard panels are 4″ thick, but optional 2″ and 6″ panels are available to meet special requirements.
Type HTL acoustic panels are designed for applications where a higher transmission loss is required. Standard KINETICS type HTL panels are fabricated with an outer solid shell of 16 gage and inner perforated shell of 22 gage steel with a high mass septum added for increased acoustic performance. Panels are stiffened with 18 gage internal channels and edge rails. The acoustic grade fill is 2.5 to 6 pcf long strand fiberglass or mineral wool depending on the application and are inert, mildew resistant, vermin proof and incombustible. Panels are available in 4″ or 6″ thickness.
Materials
Outer and inner shell materials are available in standard galvanized steel, Type G90, mill phosphatized (satin) finish galvanized steel (readily paintable), stainless steel, Types 304 and 316, aluminum and aluminized steel. Standard material gages for solid outer shell are 18 ga. and 16 ga., perforated (23% open area) inner shell is 22 gage. Septum panels and panels with solid outer and inner shells are available. Factory applied powder-coat finish is available as an additional option.
All internal sound absorbing media used in NOISEBLOCK™ panels meet the requirements of NFPA-90A and surface burning characteristics per ASTM E84, with maximum flame spread rating of 25 and smoke developed rating of 50. Other media are available offering more stringent flame spread index and smoke developed index. The media is available both unlined, lined or bagged using a specialized film or cloth barrier and acoustic spacer. The insulation is under compression so as not to allow settling of acoustic media within the panel.
Standard Panel Dimensions
NOISEBLOCK™ panels are available in standard designated widths of 21.625″ and 45.625″ and lengths up to 144″. Other widths and lengths are available by request.
Thermal Performance
The insulation materials used in NOISEBLOCK™ panels at 75˚F have maximum thermal conductance values of 0.06 BTU/hr-ft2-˚F (4″ thick) and 0.12 BTU/hr-ft2-˚F (2 inch thick). Thermal resistance values are R17 (4″ thick) and R8 (2″ thick). Other insulation materials yielding higher thermal performance values are available.
Silenced Ventilation Systems
Kinetics Noise Control ensures the enclosed equipment or process is properly ventilated as to prevent overheating by choosing from our expansive product line of circular (VCS), rectangular straight (VRS) and elbow (VES) absorptive or reactive silencers and fixed-blade acoustic louvers (KCAL/KCPL/KCAC).
