‘’Out of sight is out of ears’’ can be referred as the basic principle of blocking or diffraction of longer wavelength or same wavelength size than the barrier size. An acoustic barrier (sometimes also called a ‘noise barrier’) is designed to protect people close to the source of a noise. Common noises which can be treated with acoustic barriers include construction work, industrial sites, roads/motorways, and quarries. Sound absorptive surfaces reduce the reverberant build up between parallel barriers and other reflective surfaces- this enhances the ability of barrier to attenuate noise.
Aircoustics products and structures are designed to build in accordance with numerous international standards and specifications. AFZE has been assessed and accredited with the ISO 9001: 2008 Quality standard.
Aircoustics designed AAB model is a range of acoustic barrier which Offer exceptional transmission loss i.e., 14 Db at 125 Hz**.
** Sound data is available upon request- for more information on design and product please contact our sales office.
** Design calculation for barrier is available by our expert Acoustic Engineers. **
Aircoustics offers complete design, manufacturing and installation services including all necessary structural steel work or an expert supervision is provided to ensure the performance is not hurt.
Free standing barriers: AFS/ ASFS- Usually designed to have both sound absorptive and improved STL characteristics. Material could be Aluminum or Steel as per specification.
- AFS- designed long side the noisy equipment/ source.
- ASFS- designed for free standing between multiple sound source/ equipment.
- Offers excellent Sound Transmission Loss (STL) characteristics.
- Suitably designed for rapid assembly from prefabricated components.
- Desired height can be achieved by stackable panels between steel posts.
- Cladding module: A special design that comes with acoustic panels which are fabricated in such a way to easily attach to a new or existing structure thus improving the acoustic performance. Material available in Aluminum and steel.
Model**
- AC : 64 mm thickness
- AC12: 76 mm thickness
- AC38: 102 mm thickness
- The sound absorptive cladding modules are good for reducing reflective sound
- Suitable to apply on new and retrofits
- Can be applied on metal/ wood/ brick/ concrete/ stone or any other noise reflecting surfaces.
- Enhances the sound absorption on 125 Hz
Louver screens: are aesthetically pleasing looking product that allows the ventilation yet provides acoustic performance suitable for mechanical service plants (pumps/ compressors and chillers).
- Thick- shield and Thin- shield louvers provide and aesthetic screen.
- Highly effective and stylish acoustic screen and can be used to snub the noise for pumps, compressors and chillers and still a proper ventilation is achieved.
