New bell sound in the car: This is how we react to snowy roads!

New bell sound in the car: This is how we react to snowy roads!

The contemplative time before the festival not only brings with it lights and gifts, but also specially designed sounds that accompany us. The sound of bells is often described as pleasant and calming. Nowadays, however, the world of sound is changing, especially in traffic. According to the reports of Northern Courier There are fewer reindeer sleighs on the road these days despite the winter conditions, which means that many people are less accustomed to this sound.

The modern automotive industry is increasingly taking on the challenge of customizing vehicle noise. More and more attention is being paid to ensuring that acoustic signals are not only useful but also pleasant to perceive. The transition from conventional vehicles to electric vehicles brings with it new challenges, especially due to the almost silent electric drives. Accordingly, designers design noises in such a way that flashing noises, for example, appear less intrusive. The KIT uses innovative measurement methods to realistically record and improve vehicle noises.

Legal requirements and challenges

The legal requirements for acoustic warning systems mean that vehicles must be equipped with various noise signals. These signals warn, for example, at temperatures below 4 degrees Celsius or when the lane assistant is inactive due to snow on the camera. He also reports this Northern Courier. Manufacturers are therefore faced with the challenge of adapting all new vehicle models to modern European standards. Signaling must not only ensure that traffic signs are recognized in a timely manner, but also indicate other potential dangers.

In order to help manufacturers with this task, the KIT Institute for Product Development supports interested companies in investigating vehicle noise. KIT's scientific approaches include methods for validating vehicle noise during the development phase, which makes complex subject studies unnecessary. In this way, an acoustic design of the future can be developed that is equally beneficial for manufacturers and customers.

Research and innovations in vehicle acoustics

In addition, advanced research and experimental and numerical simulations of acoustic components are carried out in vehicle acoustics. Loud Fraunhofer Acoustic absorbers and sound reduction methods are being tested, such as micro-perforated rims, which are used to minimize rolling noise.

The use of an all-wheel roller dynamometer also enables the precise analysis and optimization of vehicle interior and exterior noise. The most modern measurement techniques are used to identify harmful noise sources and develop appropriate solutions. Vehicles should be equipped with advanced noise insulation so that they are both functional and comfortable.

Overall, it shows that acoustic innovations in the vehicle industry not only overcome technical challenges, but also contribute to the emotional appeal of drivers and passengers. The sound worlds of cars are becoming increasingly important and the acoustic experts responsible for them are making a valuable contribution to the mixture of technology and aesthetics in road traffic.
