I've been tasked with creating a small, immersive sound installation for a public library's new "quiet contemplation" room, and my concept is to use the faint, real-time sound of the building's own electrical systems—step-down transformers, HVAC hum, server fans—but processed to be harmonious and barely perceptible. I have a modest $800 budget, a two-week install window before the room opens, and permission to non-invasively tap into existing conduit runs. My dilemma is technical and aesthetic: I'm debating between using simple contact mics and piezo pickups fed into a granular synthesizer on a Raspberry Pi, or a more direct approach with induction coils to capture electromagnetic fields, but I'm worried the latter will be too abstract and lack the tangible, architectural "breath" I'm after. The library's head librarian is supportive but nervous about anything that could be construed as noise, so the margin for error is zero.
