Noise measurement in the state capital of Kiel (Odala)

General
Different road noise levels are provided in this dataset.

The data will be provided within the framework of the Odala funding project.

Data model
The data can include different sensor types and manufacturers. In order to harmonise the data, these are combined into a uniform data model. Not every sensor measures all specified values. The data is provided in the “NoiseLevelObserved” data model.

This builds on the Smart Data Model “NoiseLevelObserved”:

Measured and calculated values

• LA1 (sound level exceeded in 1 % of the measurement time – statistically calculated)
• LA10 (sound level exceeded in 10 % of the measurement time – statistically calculated)
• LA50 (sound level exceeded in 50 % of the measurement time – statistically calculated)
• LA90 (sound level exceeded in 90 % of the measurement time – statistically calculated)
• LA99 (sound level exceeded in 99 % of the measurement time – statistically calculated)
• LAeq (equivalent continuous sound level)
• LAMAX (maximum measured level)
• Lamine (minimum measured level)
