Introduction Is this your situation ? • you need to reduce the noise emission of your machinery • you need to improve the noise reduction of your existing sound enclosure • you do not want delicate foam surfaces in your sound enclosure • you are looking for an aesthetic fiber free solution • you want to build your machine enclosure with the most functional and rugged aluminium profile system utilizing the highest level of design freedom • You need to reduce your ambient noise (diffuse sound)

MayTec "Noise Resist" General The patented MayTec "Noise Resist" sound absorber combines the advantages of perforous absorbers with the advantages of resonators (please find detailed information on absorbers and resonators on page 19). The MayTec "Noise Resist" absorber acts on a broadband frequency range like a perforous absorber and at the same time offers the small thickness of resonators. The MayTec "Noise Resist" absorber can consist of 1, 2 or 3 layers of different materials:

MayTec 1-layer "Noise Resist" MayTec 1-layer "Noise Resist" made of 1 mm aluminium Is a self supporting aluminium sheet, which is micro-perforated by a patented process to generate the optimum airflow resistance for absorbing sound. In order to optimize the efficiency of the MayTec 1-layer "Noise Resist" absorber, it is normally installed with a small airspace between the absorber panel and the back wall. The main advantages of the MayTec "Noise Resist" absorber are: • • • • • • • • • • • extremely robust dirt and fluid resistant easily cleaned, even with steam cleaners heat resistant...

MayTec 1-layer "Noise Resist" The MayTec 1-layer "Noise Resist" achieves the highest noise reduction for frequencies between 1,000 Hz and 3,000 Hz. This is exactly the frequency range of most technical applications (motors, pumps, compressors, ventilators, etc…). By increasing the airspace of the MayTec 1-layer "Noise Resist" to the back wall it is possible to increase the noise reduction dramatically in the lower frequency range to about 1,700 Hz (as per the following diagram) Average absorption coefficient of the MayTec 1-layer "Noise Resist" Application Reference Food preparation areas...

MayTec 2-layer "Noise Resist" MayTec 2-layer "Noise Resist" absorber made of 1 mm aluminium and acoustic foam The MayTec 2-layer "Noise Resist" absorber consists of the 1 mm thick, micro-perforated aluminium sheet attached to a special acoustic foam. The MayTec 2-layer "Noise Resist" absorber is available with 2 different foam thicknesses: 25 mm and 50 mm (≈ 1" and 2"). The combination with the acoustic foam significantly increases the noise reduction of lower frequencies compared to the 1-layer "Noise Resist" absorber (see following diagram). For easy assembly to walls or machine enclosures...

MayTec 2-layer "Noise Resist" After the assembly the aluminium surface faces the noise source. The main advantages of the MayTec 2-layer "Noise Resist" absorber are: • increased noise reduction of lower frequencies • elimination of the absorber’s resonance frequency by combining 2 different materials (double glazing effect) • the acoustical foam is non-combustible and heat resistant • the aluminum surface prevents fluids from entering unless they are under high pressure and the acoustic foam can be treated (at an extra cost) to be water and oil resistant • well protected against mechanical...

MayTec 2-layer "Noise Resist" Application Reference Typical technical applications are sound enclosures of pumps, generators, compressors or motors. Remark: When the MayTec "Noise Resist" absorber is glued onto a panel element of an enclosure, it is absolutely important to remember, that the panel element has a high stiffness. Otherwise low frequencies will stimulate vibration of the complete panel element. In this case the panel element would work as a "loudspeaker" and would be acoustically transparent for low frequency sound. So it is recommended to use a panel element with a high mass...

MayTec 3-layer "Noise Resist" MayTec 3-layer "Noise Resist" wall elements For the assembly of sound isolation rooms or sound enclosures, MayTec offers modular wall and ceiling elements with the 3-layer "Noise Resist" absorber. The outside shell of the wall element consists of a 2 mm steel sheet. The middle of layer is made of 50 mm acoustic foam. The innermost layer is the 1 mm thick perforated aluminium sheet. The 3-layer MayTec "Noise Resist" absorber panels are framed with a 40×40 profile structure to generate a compact and rugged wall or ceiling element.

MayTec 3-layer "Noise Resist" The first step for the installation of sound enclosures or sound isolation rooms is to align the posts made of 80×80 profiles and to bolt them to the floor. Afterwards the connector heads which are sticking out of the pre-assembled MayTec "Noise Resist" wall elements are slit into the slots of the posts and the connectors are tightened. The modular design of the MayTec "Noise Resist" wall elements guarantee an easy and fast assembly of sound isolation rooms and sound enclosures.
