"FensterKlang" - Contributing to the personalized selection of windows by making sound insulation audible

"FensterKlang" is designed to specifically reduce the noise load on the population as well as to ensure that new windows are selected cost-effectively and sustainably. This makes it easier to choose windows that take into account situation-dependent noise emissions and personal, subjective perceptions.

In addition, window designs can be matched in a more differentiated and situation-related manner. Heat pumps, for example, have rotating elements that can generate tonal and thus disturbing noise. By specifically matching windows with the methodical approach, building on "FensterKlang", the technical development of the industry can be promoted in an interdisciplinary way and the best possible noise control can be achieved for the case in question.

Fraunhofer IBP also develops further target and evaluation parameters based on objective and perception-driven noise analyses. The subject area of psychoacoustics forms the basis for this, which has already been used for many years, for example in the automotive industry, in product development.

This has resulted in scientific consulting and support services for the industry, which benefits from established approaches to innovative product development in the context of building acoustics. Professional perception studies with test persons round off this consulting and development service in a target-oriented manner.

The “FensterKlang” concept can be used to extend acoustic tests on building components on the basis of measurements. Fraunhofer IBP's accredited test laboratory for building acoustics and noise immission control has several acoustics laboratories, such as a test facility for measuring the sound insulation of windows. Extending the results of laboratory measurements for evaluating the acoustics of components in and on buildings to include subjective, perception-related parameters brings together experts in building acoustics, room acoustics and psychoacoustics at Fraunhofer IBP on an interdisciplinary basis. You benefit enormously from our many years of experience in acoustic measurement technologies, their application in accordance with relevant standards, as well as the planning, implementation and statistical evaluation of perception studies.
