DB agrees new ‘Noise Protection Target 2030’ with German government
https://www.globalrailwayreview.com/news/116357/db-noise-protection-target-2030/
As I've lived along railway tracks, I know what it's like.
As a result, I was accustomed to noise. But, it will depend on an extent of noise level. So, DB should take measures for noise louder than a threshold which is the loudest volume people can tolerate with. Otherwise, they don't have to do anything.
