I remember reading something about how different kinds of music had different kinds of effects on plants. If my memory is correct, symphonic music was beneficial to plant growth whereas highly dissonant music wasn’t. Of course, the study could have been affected by the person caring for the plants and what kind of music they liked (in one case they might leave the room before watering the plants because they couldn’t stand the music).
But this sounds like a great idea. Some professional programmers and designers sit in very technically advanced chairs where their position is changed automatically, the monitor follows the position of the chair, the phone is part of the chair near the head, and where your music could be piped in to increase mental focus and calm him/her down if they’re upset. You might be surprised by the number of uses your idea could be put to.
