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.

Recently, we get the new projector front-ends from Atlas Elektronik for our MIMO SONAR system. This was part of the "Großgerät" which was obtained with the help of the German research foundation (DFG). Now we are able to perform underwater experiments that will show if our ideas and corresponding realt-time algorithms also works in real environments.

We would like to thank all of our ...
