Wouldn&#x27;t an epic startup idea be to build a ventilated, sound-proof, vibration-proof box for sleeping in and then sell it directly to consumers? I imagine it would be a hell of a lot cheaper than sound-proofing an entire house or having to move because of crappy neighbors and I&#x27;d sure as hell buy one if it existed. A device like that probably would have saved me from having to move from my last house under quite bad terms, plus imagine being able to have parties in your house and then being able to sleep when you get over it without having to wind down the whole party. There&#x27;s probably multiple user-cases for such a device but I honestly don&#x27;t know how practical this would be to build - acoustics != my field.
