Yes, phoneguywayne......it is used in commercial office space....
cube city ....to kill the drone of people on the phone, chatting, phones ringing, copiers running, etc. Think of it as a paging system that has music playing all the time... only the music is white noise. :shhh:
See you aren't so sheltered after all. Find yourself a sound / paging /audio company that has an acoustical engineer to design the system. Placement of the speakers and the audio load is very important.
On the lighter side, the subliminal messages improve productivity and brain wash the worker bees.......
Good luck with your project. :thumb:
