Why sound quality in trucks’ cabins matters: the example of Volvo Trucks


This is Vera.

Vera is an electric, autonomous vehicle that is designed to optimize transport in highly-repetitive, short distance flows with large volumes of goods.

Vera, and its inventor, the company Volvo Trucks, will certainly influence the future of road transportation and ensure that it becomes safer, quieter and more efficient.

But until Vera is here, trucks will be driven by humans. Humans who get tired, bored, hungry, sleepy. Humans who make errors. Humans who are also capable of enjoying the agreeable sensations of a smooth ride.

Theresia Manns is one of these persons who believe that truck driving should be a safe, comfortable and enjoyable experience.

In her role as an NVH engineer within the Volvo Trucks Company, she understands the impact of ride comfort on attributes such as quality perception, driving pleasure and safety.

“My focus is to improve the sound quality in the truck’s cabin,” she says. “Sound quality is definitely not a negligible aspect of truck design and development. Poor sound quality and the occurrence of disturbing noises cause additional stress and mental fatigue for the driver.”

Manns and her colleagues work to investigate the origin of noise problems and propose appropriate countermeasures, with the ultimate goal to minimize the negative impact of acoustic annoyances inside the cabin on the driver’s stress and fatigue.

The NVH engineering team at Volvo Trucks relies on Simcenter Testing Solutions to improve cabin sound quality and quickly identify and analyze the origin of annoying noise, with the help of the Simcenter Solid Sphere Array and Simcenter Testlab 3D Acoustic Camera software.
