The reason the subconsious part of the brain draws attention to a sound is that one of its key roles is to warn in case of potential danger. When “primitive” unconscious sound processing indicates that the situation might not be completely safe, it recruits conscious processing for a more advanced analysis. We, in this case the unconscious sound processing systems, are rather safe than sorry. Basically, humans and animals like sounds that are indicative of safety, sounds of other individuals feeling safe, relaxed, or having fun. These sounds (unconsciously) help the listener to relax, enjoy, or focus attention. This explains why the blanket of non-natural sounds (such as traffic or machines) in our societies leads to a degradation of the soundscape quality: these sounds mask the pleasant (safety-indicative) sounds that we prefer. The results is that the auditory environment becomes more boring, less reassuring, and overall less pleasant.
