Noise Estimation
In the chapter "Insights into Automotive Noise PSD Estimation Based on Multiplicative Constants", authored by Vasudev Kandade Rajan and Gerhard Schmidt, of the book entitled "Intelligent Vehicles and Transportation - Vehicles, Drivers, and Safety" a noise estimation scheme was presented. Here, you can find example code that you are allowed to use for non-commercial applications.
Audio examples
The noise recording was made in a car driving at about 100 km/h. The speech example (female, German) was taken from the (free) SPID corpus. Details can be found here.
Code listings
Please have a look on the code listings. If you want to use it, we recommend to download this zip file. It contains also the required examples (audio files) and the folder structure that is assumed in order to run the Matlab code correctly.

Science Day took place in Kiel and at the Faculty of Engineering on 25 September 2026. The DSS group contributed two demonstrations that gave visitors an insight into current research on signal processing, underwater acoustics and speech signals.
