The design expertise of Newtech Engineering systems can meet any application where noise abatement and weather protection
Design Specifications ;
Some of the design characteristics of our acoustical assemblies include:
Acoustical Properties :
Our acoustical assemblies are specifically adapted for different levels and different types of noise, including tonal and low frequency noise sources. The design of each takes into account the following acoustical factors:
Drop over enclosures can be used when it is necessary to suppress noise pollution from machinery either fixed or mobile. Legally employers must protect their employees from continuous high noise levels above 85dB (A). Most of our acoustic enclosures are completed at our factory and are ready to go directly into service. Installation is simple and can be done by the customer. On the other hand, site work may be necessary when the enclosure is large and cannot be transported in one piece or when it needs to be mounted in congested spaces. Then we supply the enclosure in panel form with quick-acting catches and assemble it on site. The enclosures can be constructed from any outer materials for a finish to your requirements and also all weather conditions. Each acoustic enclosure installation is treated individually. Site evaluations are carried out to determine the type of enclosure required.
Pre-fabricated insulated wall panels of 100mm to 300mm thickness will be mounted to the noisy room walls, with Acoustical Doors & Louvers. IT can be used when it is necessary to suppress noise pollution from machinery. Most of our acoustical wall panels, Doors & Louvers are completed at our factory and are installed in the customer place. Site evaluations are carried out to determine the type of insulation required.
Acoustical Doors :
Acoustical doors incorporate mass, damping and absorption concepts to effectively block sound transmission. Doors are triple-hinged and are constructed with flush faces to prevent noise leakage. Seals, caulking, hardware and frames are integrated into a door's design to ensure acoustical integrity. Features of doors supplied by Newtech include:
Newtech offers single or multi-paned sound proof windows as part of our complete acoustical design package. Windows range in thickness and acoustical performance. Similar to acoustical doors, seals, sills and hardware form an integral part of the sound proof window design.
Acoustical enclosures :
All our sound proof enclosures are designed to allow the maximum aspiration and cooling airflow required so the machine does not overheat. Weather louvers, acoustic louvers, splitter and baffles are provided to suppress the noise where require. Anti-Vibration mounts can also be provided where required.
Many special features are available depending upon the application. Some types of equipment such as generator sets and air compressors are self contained, but may require features including:
The design of the acoustic enclosure is capable of variation to many machine noise problems. Requirements can range from a small noise reduction, in which a minimal solution will be adequate, ie. An enclosure which may not fully enclose the machine, can achieve 5-10 dB (A) noise reduction. More elaborate enclosures can achieve a noise reduction of greater than 30dB (A), and can consist of one enclosure inside another.
Painting of the equipment can be included in our manufacturing, and will vary from finishing with machine enamel to two-pack epoxy, powder coating or other options.
Acoustical Treatment :

Equipment such as presses, foundry shake-out machines, nail making machines, and granulators require an inlet and outlet for entry and exit of the product. These openings need attenuation to minimize noise emission. Fans emitting considerable noise through the casing will also need to be enclosed and therefore penetrations will need to be provided for the air inlet and outlet. A small ventilation fan may be needed to remove the electric motor heat.
