The main aim of the project meeting in June 2019 in Kielce was creating a noise map of Kielce by both Czech and Polish students.

On Tuesday after the opening conference, the expert from University of technology Kielce helped us with quick calibration of the mobile phones.

On Wednesday, students from Bohemia and Poland divided into several groups and they measured noise levels in different parts of the city.

There were some minor complications during the measurement.
For example, measurements were partially devalued by the wind which was blowing into the microphones of the mobile phones.
There were also problems with compatibility of the files generated from iOS and Android operating systems.

Finally, we merged the data into one csv file and created the first common noise map.
