The event, which took place in cooperation with the University Hospital Jena at the Ernst Abbe University of Applied Sciences Jena, celebrated its anniversary edition in 2025 and presented both established and new topics in the field.

The conference took an in-depth look at the phenomenon of noise – from its generation and measurement to its effects on health and the environment – as well as modern solutions for noise reduction and sound optimization.

The focus was on how sound affects our everyday environment.

The aim was to bridge the gap between theory and practical acoustic challenges and to put innovative ideas from research and development into practice.

The 20th Jena Acoustics Day not only marked a milestone in two decades of research into acoustics, but also paved the way for future developments in noise reduction and a better understanding of sound dynamics.

Practical solutions for noise reduction and sound optimization from Gefell

Microtech Gefell is a renowned manufacturer with a long tradition in precision audio technology. A significant part of the product portfolio is dedicated to acoustic measurement technology, which is used to monitor and analyze environmental noise, among other things.

When it comes to environmental noise, precision is everything. For example, scientists, environmentalists, urban planners and authorities depend on accurate and reliable measurements to assess noise pollution from traffic, industry or construction. Microtech Gefell’s measurement microphones are designed to capture even the smallest fluctuations in sound pressure levels. This accuracy is crucial when studying environmental noise, from assessing the low-frequency hum of urban infrastructure to the complex sound distributions in nature and buildings. Gefell’s instruments often form the backbone of studies and solutions that contribute to the development of strategies and their practical implementation to ensure that strict noise standards are met in facilities, public spaces and nature.
