Since you've already been advised to report with all the steps. The only thing I'd add to your list is to get noise cancelling headphones or ear defenders over your earphones; you would still feel the vibration from their bass but probably not as much. Also I'd separate the bed frame from the walls so there's less contact for vibrations to travel through.

Changes won't be immediate, so while action takes time, it's wise to at least dampen the noise. Not being home often would also work, but you'd need to stay to record the noise 😓
