Plug and Play‘s Overview of 4Silence

4Silence is offering a hardware and software solution that allows its customers to easily localize and identify their acoustic issues.

4Silence's solution identifies acoustic issues under actual operating conditions by using our measurement device: the Sonocat.

4Silence's solution can be applied in any industry. The application of our solution is focused on business areas such as R&D, manufacturing, consulting, quality control, and maintenance.

4Silence is currently focusing on building new customer relationships with small, mid-sized or large companies in the automotive, aerospace, construction and general R&D sectors.

Project Teaser: EXPO2022by STARTUP AUTOBAHN powered by Plug and Play

Mercedes-Benz and 4Silence worked on identifying and measuring noise leakages in driving vehicles

in cooperation with the STARTUP AUTOBAHN partner Mercedes-Benz AG

To reduce noises inside a vehicle, it is essential to identify the most dominant transfer path from sound sources outside the cabin to the passenger’s ears inside the cabin. While driving, this is difficult to accomplish, due to the large number of reflections in the car. Using 4Silence’s new technology, as implemented in the Sonocat measurement device, Mercedes-Benz and 4Silence could quickly localize noise leaks, as the Sonocat is able to differentiate between the source and its reflection. The experimental facilities and experts of Mercedes-Benz enabled 4Silence to increase their experience in the automotive industry.
