Technicon Acoustics uses our expertise to help heavy truck and other specialty vehicle OEMs reduce sound, heat, and vibration problems while increasing passenger and driver comfort during operation. By improving vehicle performance and enhancing the customer experience, we help OEMs improve the customer perception of their products and their brand. 

We offer thermal and acoustic solutions for a variety of heavy trucks and specialty vehicles, such as: 

  • Semi-trucks 
  • Emergency vehicles  
  • Delivery vehicles 
  • Military vehicles 
  • Recreational vehicles 
  • Buses
  • Mass transit

Headliners

Headliners

If the headliner is left uninsulated, noise can reverberate inside the cab giving the operator a sense of being inside a “tin can”. Adding
a noise reduction material—such as perforated vinyl foam—as a headliner or an insulating layer of foam or fiber 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.

Exhaust

On the Hood - Exhaust

In heavy trucks and other specialty vehicles, exhaust pipes generate significant amounts of heat that can damage nearby components. The incorporation of exhaust wraps helps maintain exhaust gas temperatures inside of exhaust pipes and lowers the surface temperature of exhaust pipes to protect nearby components from thermal damage. Our Tech Shield Sleeve™ features a proprietary blend of highly texturized fiber and cure-in-place structure that make it one of the most unique, versatile, and efficient exhaust pipe wraps available. Its one-of-a-kind, state-of-the-art design allows for quick and easy installation without sacrificing performance quality. Since the sleeve is designed to fit tightly, it prevents the intrusion of debris and dust that could compromise vehicle performance.

Engine Compartments

The engine is the component that contributes the most to noise levels within a truck’s operator cab. It also generates a significant amount of heat, which can lead to uncomfortable temperature conditions inside of the cab. For these reasons, OEMs often integrate acoustic absorbers and thermal insulation (e.g., TechShield) into engine compartments, which ensures cabs remain at comfortable noise and temperature levels. Blended materials (e.g., PF-091) are highly beneficial to applications that require acoustic and thermal insulation since they offer both sound absorption and heat shielding properties.

Floormat

Road noise is a major contributor to NVH in on-road vehicles. If the floor of the cab is left uninsulated, noise can easily travel into the operator cab. The addition of floor mats made from mass loaded vinyl is a simple but effective solution to managing sound levels inside an operator cab. They are designed to reduce the amount of sound transmitted through materials, which dampens noise and/or block it from entering the cab. Our acoustic floor mats are available in a variety of materials and can be custom cut to fit the cab floor

Outer Cab

  • Acoustic Solutions

    The interior surfaces of an operator cab’s walls and roof can be layered with acoustic material (e.g., polyester fiber) to improve acoustic and thermal conditions for the comfort of the truck’s passenger(s).

  • Vibration Damping

    Traveling over bumpy roads and air turbulence can cause the roof and wall panels of the operator cab to vibrate. If left untreated, these vibrations can lead to airborne and structural noise. The integration of vibration damping materials into the operator cab’s roof and walls mitigates these issues.

Acoustic and Thermal Insulation for Semi-Trucks & Emergency Vehicles 

Tractor trailers and emergency vehicles generate significant engine and road noise during the course of normal operation. That noise can have a damaging effect for drivers and passengers. This risk is especially high for those who spend extended periods in the vehicle, such as long-haul truckers and military personnel, among many others. Over a protracted period of time, too much road noise and vibration can lead to unsafe driving conditions.  

semi truck acoustic treatments

Technicon Acoustics can target these problems in multiple ways:  

  • Cabs. Our range of composite solutions contribute to reduced road noise, while our custom-fitted selection of acoustic and thermal solutions prevents vibrations and accumulated heat from entering the interior of the vehicle, including the cab or sleeper area. The headliner can also be outfitted with perforated vinyl foam to add an additional layer of acoustic protection against noise. 
  • Floor matsWe can install barriers crafted from mass loaded vinyl in the vehicle’s floor mats to further mitigate road noise and vibration. Mass loaded vinyl consists of a thick, yet pliable sheet of vinyl infused with metal particles to give it extra mass. This barrier helps disperse external vibrations as they enter the interior of the vehicle. 
  • Engines and TransmissionSimilar noise damping materials can be placed between the engine and operator thelp reduce vibrations and noise, as well as noise from shifts in the vehicle’s frame as it navigates the road.  

Control Essential Equipment Heat and Noise with Technicon Acoustics 

The engine in your average transport or emergency vehicle is large and generates significant power, heat, and noise. Our trademarked Tech Shieldcan be applied to the firewall between the engine and the driver cab offering protection from heat buildup.  

fire truck acoustic and thermal treatments

Exhaust pipes create another heat hazard on these heavy truck and specialty vehicles. Because they operate over a long period of time, they can become dangerously hot. OurTech Shield Sleeve™ fits over the exhaust pipe and serves a dual purpose by: 

  • Trapping heat for better diesel particulate filtration  
  • Providing a barrier to prevent operators from touching the hot exhaust pipe 

Our Tech Shield Sleeve helps your diesel engine operate at maximum efficiency while protecting sensitive components and materials that surround the exhaust.  

Thermal and acoustic materials are placed within the wall and ceiling panels of emergency vehicle. This helps combat both heat soak and road noise which can be detrimental in this setting. For heat soak, our thermal material stabilizes the environment to keep internal temperatures comfortable by blocking outdoor heat and trapping cool air. These treatments are commonly done in the body of ambulances, but can also be done in cabs of other emergency vehicles like firetrucks. 

Emergency vehicles don’t always follow the rules of the road. They regularly have to exceed the speed limit and make sharp turns which can generate additional noise in the vehicle’s frame. We can design sound-damping materials in vertical and horizontal surfaces of specialty and emergency vehicle’s interior to help alleviate any added vibrations.  

Technicon Acoustics Success Story: Emergency Vehicles 

Safety is essential for proper operation of emergency vehicles. Emergency relief crews need to communicate with each other and their dispatcher during a crisis situation. The emergency vehicle’s interior needs to be free from as much acoustic disruption as possible to facilitate appropriate communication and ensure that passengers, patients, and rescue workers remain safe. 

ambulance acoustic treatments

In the aftermath of 9/11, first responders came to understand how essential noise reduction inside emergency vehicles was. Many emergency fleet vehicles were destroyed in the course of service. Technicon Acoustics worked with one emergency vehicle manufacturer to reduce cabin noise and facilitate speech communication between EMT and hospital personnel which helped them win a major contract with the city of New York to replace emergency fleets going forward. To learn more about how we were able to help first responders with our acoustic solutions, please watch our video
