At Technicon Acoustics, we provide noise-reducing and thermal treatment solutions for OEMs who manufacture desired construction and agricultural equipment. To manufacture equipment that is quieter and safer in the end, acoustic and thermal strategies must be considered by OEM engineers, buyers, and administrative individuals from the start of any project.
Thermal and Acoustic Treatments in Construction Equipment
Construction noise is usually a result of the equipment. Since construction commonly occurs around civilians and systems are manned by operators, the implementation of noise-reducing acoustic material for heavy equipment OEMs is increasingly important for the overall safety of their products.
Restricting raised noise levels begins with managing the source of the noise before it reaches an unwanted or damaging level. One way this is achieved is the use of vibration damping material, which is an effective measure for reducing the loud vibrations of working equipment such as:
- Articulated trucks
- Material handlers
- Off-highway trucks
- And more
Exposure to high levels of excessive noise can be dangerous to machine operators, which in turn can be dangerous for everyone on the crew and around the site.
To keep employees safe with their hearing intact, acoustic absorptive material should also be attached and lined to the hard-reflective surfaces of the operator cab to achieve sound absorption. At Technicon Acoustics, we recommend the use of porous materials such as foam and fibers to do this effectively. Furthermore, acoustic and thermal treatments to engine compartments and floor mats should also be considered.
If this 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.
OEM’s often incorporate exhaust heat wraps or blankets as a means to maintain exhaust gases temperatures inside the exhaust pipe and to lower the surface temperature of the exhaust to ensure nearby components are not damaged.
Our proprietary blend of highly texturized fiber and cure-in-place structural cords make the Tech Shield Sleeve™ one of the most unique, versatile, and efficient exhaust pipe wraps available. The unique state-of-the-art design allows for quick, easy installation while providing exceptional performance. Designed to fit tightly, Tech Shield Sleeve™ prevents the intrusion of debris and dust that could compromise equipment performance.
The engine is the biggest contributor to noise levels in an operator cab. For this reason, OEMs integrate acoustic absorbers into their engine compartments. The engine also generates heat, which can lead to uncomfortable conditions inside the cab. For these situations, OEMs add thermal insulation (e.g., TechShield) to their engine compartments. This ensures cabs remain at comfortable temperatures.
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.
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.

Thermal and Acoustic Treatments in Agricultural Equipment
There are a variety of agricultural machines and equipment that produce loud noise. The loudest equipment and the one most in need of sound-reducing techniques are tractors. Its elevated noise causes fatigue for the operator, which may reduce the amount of time they can work and perform vital tasks.
Due to changing legislative rules surrounding noise requirements for tractor operation, the implementation of noise-reducing materials is essential to a tractor’s design. The output of a tractor’s noise comes from the machine’s engine. The engine’s noise is caused by the intake, casing, cooling fan, and valve, as is combined with the noise caused by the exhaust. By attaching damping material to the engine housing and body parts, a reduction of the loud rattling and vibration can be achieved.
Not all tractors have a cab, but those that do require further noise reduction methods. If there is a cab attached to a tractor, the vibration of the cab will also cause a raised noise level. Similar to methods used for construction equipment, padding the cab of a tractor with absorptive material is a recommended solution. This material should be attached to the walls, headliner, and under the floor mat of the tractor’s cab. These strategies are effective in reducing noise levels, which in turn helps keep operators hearing ability safe.
