According to a study performed by the American Industrial Hygiene Association in the early 2000s, over 500,000 construction workers are exposed to noise levels that pose a potential risk to their auditory health and well-being. In addition to affecting the working conditions for these workers, the sound produced at construction worksites affects the living quality of the surrounding communities and environments. One of the most significant contributors to these elevated noise levels is the construction equipment employed, such as excavators and bulldozers.

By implementing noise reduction measures—such as damping foam, acoustic absorbers, and acoustic barriers—in construction equipment, industry professionals may not entirely eliminate noise pollution, but they can reduce sound to more tolerable levels. While these materials are available as aftermarket products, it is much more efficient for original equipment manufacturers (OEMs) of construction equipment to keep in mind acoustic design—including noise reduction—when developing and constructing their products from the beginning.

At Technicon Acoustics, we have the industry experience and knowledge to deliver high-quality equipment noise reduction and soundproofing solutions to OEMs. By bringing the noise produced by their equipment to more acceptable levels—minimizing the impact on machine operators and the surrounding environment—we improve the marketability of their products, enhance consumer perception, and facilitate compliance with regulatory standards.

Benefits of Noise Reduction in Construction Equipment

The integration of noise reduction and soundproofing components in construction equipment translates to significant benefits in the workplace. For example, lower noise levels in construction worksites can lead to:

  • Greater concentration and better communication. Reducing the amount of sound generated by construction equipment enables workers to concentrate and focus on the task at hand without being distracted by equipment noises. Additionally, it facilitates better communication between individual workers during collaborative tasks and/or potentially hazardous situations.
  • Lower rates of error and injury. The greater concentration and better communication achieved in quieter worksites also result in a lower risk of worker error and injury.
  • Reduced worker stress. Sound significantly affects a construction worker’s physical and mental health. Elevated noise levels can lead to hearing loss and other ear-related issues as well as cause emotional stress that results in diminished worker productivity. Lower noise levels in the worksite alleviates these concerns.

Construction equipment that facilitates these benefits are more appealing to consumers, so it is in the best interest of OEMs to integrate such acoustical solutions in their equipment.

Using Technicon Products to Reduce Noise

At Technicon Acoustics, we provide a variety of products to help customers manage the noise produced by their equipment in economical ways, including:

  • Vibration damping, for reducing noise from vibrating metal panels. Panels can be treated with our materials to disrupt the resonant frequency, reduce secondary sound generation, and limit structural vibration. Damping material is extremely light and effective, allowing for the reduction of noise without adding too much weight to the equipment’s components.
  • Acoustic absorbers (Product: Polyether Foam AF-021), commonly used for unwanted noise in engine compartments, this reduces airborne noise by absorbing the sound waves.
  • Acoustic barriers, blocking noise transmission. While absorbers reduce the amount of sound reflecting off a hard surface and spreading through the air, barriers stop sound waves from getting through the material to the other side of an equipment enclosure. Barrier composites are crucial for machine operators as they are placed around the base of control levers to block sound leaks and prevent them from reaching the cab.
