This is nice map about noise level so I want to say about noise barrier wall which is one of the effective material for reducing all of noise from house and I use this material and get comfortable now.
You can generate an analysis grid, and colour it with custom values. So basically you need some data about the noise level. But I have no idea, how to assign them, maybe a value per street-segment?
Check their website for more information, it is pretty interesting, and they have a lot of study cases. https://decodingspaces-toolbox.org/
