The joint project "Energy-efficient cabin systems and interior (KASI)" is concerned with thermal and acoustic comfort in the galley/door area of an aircraft.

To reduce road traffic noise, Fraunhofer IBP is conducting studies on motorcycle noise and on the potential of quiet tires.

Acoustically-designed façade and balcony elements - with sound-absorbing materials and smart systems that reduce noise pollution.

The experts at Fraunhofer IBP are analyzing the concept of combining noise control structures with photovoltaic systems and assessing the respective carbon footprint.

The ISO 362-3 standard describes the measurement of the LUrban type testing level, consisting of a combination of the simulated pass-by in a test facility and a real pass-by. Read more here.

A team of researchers from Fraunhofer IBP now wants to turn the tables by using sound insulation systems to save energy.

Whether at home, in a hotel or at work in the office, the problem is often the same: You want to open the window to air the room, but it is very loud outside. After a short time, you close the window again to avoid the noise. The solution: automatic windows that open when ventilation is required, as detected by sensors, yet also have an automatic closing function that is activated as soon as a certain noise level is reached outside the building. However, the development in the Sound Controlled Ventilation project goes beyond simple volume control. It can also filter sounds based on their type and include the indoor noise level in the decision-making process via a microphone installed in the room.

Wind Noise generated by Façade Elements can partly reach such a high sound level that the well-being of the people inside the building and outside in the immediate vicinity can be affected.

The solution presented here follows the approach to integrate a robust, purely metallic resonator with micro-perforation in the rim.

Noise is a significant burden in everyday life and at work. Acoustically optimized products ensure more safety, comfort and the "right sound" - Fraunhofer is developing innovative solutions using polymeric materials.
