Excessive noise can severely impact the health and well-being of operators of tractors, excavators, bulldozers, and other large and heavy industrial machines. In addition to serving as a source of stress and distraction in day-to-day activities, it can cause hearing loss and other ear-related conditions over time. One method of reducing the noise levels experienced by machine operators is integrating noise reduction material in and around the operator cab. Below we provide an overview of some of the best noise reduction materials to use in tractor, excavator, and bulldozer cabs.
Noise Reduction Materials for Headliners
The term “headliner” refers to the inner roofing component of the cab. If it is left uninsulated, noise passes relatively unobstructed into the operator cab. Adding a noise reduction material—such as perforated vinyl foam—on top of the headliner or between the headliner and outer shell results in less noise entering into and reverberating through the cab. We offer this material in various colors to suit different aesthetic tastes.
Acoustic and Thermal Treatments for Engine Compartments
The engine is the biggest contributor to the overall noise levels in an operator cab. The sounds produced are continuous and—when listened to regularly and/or for long periods of time—damaging to auditory health. For this reason, OEMs and end-users may integrate noise reduction materials, such as acoustic absorbers, into their engine compartments.
In addition to producing noise, the engine generates heat. If left unchecked, it can lead to uncomfortable conditions inside of the cab. For these situations, OEMs and end-users may add thermal insulation (e.g., TechShield) to their engine compartments. These materials ensure cab interiors remain at comfortable temperatures for operators.
Applications that require acoustic and thermal insulation may benefit from blended materials, such as PF-091. These specialized materials offer both sound absorption and thermal shielding properties.
Acoustic Floor Mat Treatments
During industrial machinery operations, sounds and vibrations easily travel into the operator cab through uninsulated floors, especially around the base of the control console. Adding Mass Loaded Vinyl sound barrier floor mats can help both damp noise and block noise from entering. They are designed to reduce the amount of sound transmitted through materials.
