Pyrotek’s acoustic enclosures solve noise problem at Alpha Beta

Acoustic enclosures by Pyrotek Noise Control helped resolve a noise problem at the Alpha Beta manufacturing facility in Taipei, Taiwan.

Alpha Beta Global Tapes and Adhesives Co., Ltd., a leading manufacturer of box sealing and masking tapes found that the noise levels from machines on the manufacturing site were well above the 85 dBA level deemed safe for workers. Machinery covered over 10,000m² of the production facility.

Workers at the facility were therefore at risk of impaired performance and developing hearing loss and fatigue from the high noise in the workplace. Occupational noise exposure being one of the most common physical stressors among industrial workers, Alpha Beta sought expert advice from leading noise control companies.

With its vast experience and local engineering support, Pyrotek was awarded the contract to reduce the noise level below 85dbA.

Pyrotek worked with Alpha Beta’s Occupational Health and Safety Managers to conduct numerous noise measurements and found that most equipment generated noise levels greater than 95 dBA. A group of machines on a designated floor space were identified as requiring immediate treatment to reduce their noise level emissions.

Insulating these machines was not an option as the noise level was too high. Pyrotek opted for a two-pronged solution to resolve the problem. The side panels of the equipment were first insulated using Sorberbarrier to reduce the vibration and help absorb and reflect the immediate noise generated by the machinery.

To ensure maximum noise reduction, acoustic curtains were installed completely around the enclosure using Wavebar Outdoor supported by an engineered metal support frame. A series of flexible Wavebar barrier/ absorption panels were fabricated and secured to the frame using eyelets and hooks. The panels were joined together using Velcro to provide accessibility when needed.

On completion of the turnkey solution, the technicians at Pyrotek and Alpha Beta carried out measurements and found that noise had been reduced to levels as low as 81 dBA after the installation of the acoustic curtains, which not only decreased the amount of noise to a level allowing safe work practices but also blended with the subtle aesthetics of the manufacturing plant.

Pyrotek is currently in the process of designing a second curtain solution for Alpha Beta.
