Soundscape assessment of a monumental place : a methodology based on the perception of dominant sounds (2017)
Journal Article

Some monumental sites have unique soundscapes that deserve to be managed not only by their tourist and
cultural value, but also for enhancing the visitors’ overall impression. These sites can include a multitude of
sound sources within a variety of... Read More about Soundscape assessment of a monumental place : a methodology based on the perception of dominant sounds.
