Listen to these data-driven music examples created for our Sound Of Data project using TwoTone. The traffic data piece has been made by Steve Allen and the COVID-19 sonification by Oliver Glassl.
Using Traffic to make Music
In this composition we have used a synth to represent the traffic flow on road B40, which passes directly by the Belval campus.
The higher the pitch the greater the amount of traffic. An arpeggiated bass was used to demonstrate the fluctuations in traffic speed. And a rising scale was used to denote the time of day that the data was sampled.
The actual sound of traffic was also recorded using a stereo mic and a device called a “piezo”. These sounds have been added to give some contextual atmosphere.
The data set used is part of an ongoing data collection by the University of Luxembourg and the Luxembourg Institute of Science and Technology in the context of The Sound of Data – Science meets Music.
What if we could hear the COVID19 pandemic?
We sonified data of the COVID19 pandemic in Luxembourg, collected and kindly provided by the National Institute for Statistics and Economic Studies (STATEC).
Each beat in the track represents one day. We set accents every seventh day to mark the weeks. Different kinds of data (e.g. number of new infections or number of hospitalisations) are represented by different sounds.
Notes with a low pitch represent small numbers, notes with a high pitch represent high numbers.
The data was collected from February 1st, 2020, to February 9th, 2022.
