Hi, so I am totally new here. I live in a condo, I have a large, commercial-grade water heater right under my bedroom. It is set to a certain temperature and every time it runs, the fan is making a noise and vibration. It runs 24 hours even during midnight which makes me awake. I talk with the manager and he said that we don't have budget for the soundproof. I just want to know if there is anyway that I can damper the sound. I already put a carpet on my floor……
Thank you.
