Startup Idea : Sounds from places

When I look at a map at home, I want to hear some sounds which represent the place, and then look around to listen to. On the other hand, when I go to places like huge mall or public spaces, I want to hear some personalized selective sounds or announcement lead me to preferable spot. D-land has very simplified one. If geo tagged personal voice assistant like Siri is available, audio guide will be available anywhere other than museum. Acoustic/digital artificial sound source and its personalized arbitration system can be made. Artificial noise on electric vehicle also be included.
