A EU sponsored research project FAMOS has shown how “moderators” reduce the annoyance. A moderator can be a factor such as the appearance of the noise source, for example by planting vegetation in front of noise barriers. The report gives multiple “moderators” giving inspiration to improving the overall noise environment. You can read the Guidebook of how to reduce annoyance. It is filled with important ideas and inspiration. You may think it sounds too good to be true, but the project has been carried out by serious, widely respected researchers and their associated organizations.
