Next-Generation Rail Car Interiors: Acoustic, Thermal, and Vibration Control

Empty Modern Train Interior with Orange Passenger Seats and Aisle View

Rail car interiors have to do more than look modern. Passengers will notice how much noise reaches the cabin, how much vibration travels through the floor and panels, and how comfortable the space remains throughout the trip. For rail OEMs, those expectations have to be balanced against weight, available space, and material requirements. Refurbishers face … Read more Next-Generation Rail Car Interiors: Acoustic, Thermal, and Vibration Control

Acoustic and Thermal Foam Solutions for Next-Generation Smart Appliances

Smart appliances are expected to do more while blending naturally into the home. Consumers want connected features, efficient performance, and operation that feels refined. A washer that shakes during a spin cycle or a refrigerator that produces a noticeable hum can quickly undermine the user experience, even when the technology inside performs as intended. Managing … Read more Acoustic and Thermal Foam Solutions for Next-Generation Smart Appliances

Acoustic & Thermal Solutions for Electric Marine Propulsion Systems

Electric motors can reduce much of the noise associated with combustion-driven propulsion, but they do not completely eliminate acoustic or vibration challenges. Supporting equipment and motor mounts can still transmit vibration and noise through the vessel structure. For marine OEMs, that means the design challenge is changing. Engineers must manage the remaining noise and vibration … Read more Acoustic & Thermal Solutions for Electric Marine Propulsion Systems

Managing Heat and Noise in Electric Emergency Vehicles: Insulation Strategies for OEMs

A blurred ambulance races through the bustling streets of New York City, a beacon of hope and help in times of need.

The electrification of heavy-duty and emergency fleets is accelerating. Today’s Original Equipment Manufacturers (OEMs) are engineering electric fire trucks and ambulances that deliver instant torque, zero emissions, and the potential to power heavy life-saving equipment directly from the vehicle’s battery grid. However, removing the roar of a traditional diesel engine doesn’t mean the engineering challenges … Read more Managing Heat and Noise in Electric Emergency Vehicles: Insulation Strategies for OEMs
