Measuring levels of noise in a town
How could this scenario be extended?
To make this scenario more meaningful you can focus on different aims for collecting the data. These focuses needs different planning.
Different types of noise with the same dB-level will be result in different feelings of disturbance. So a net with datapoint of the felt noise can be compared with a net of physically measured noise. In this scenario it's necessary to collect the points as a mean of the group due to the differences of the feelings of humans. Extreme values of the differences should be analysed.
