So they do not hear the way we do but they feel the vibrations. So yes if your blasting music with a ton of base then this is not the best. More importantly though how bright is the room that the cham is in? They need a 12 hour lights on and 12 hours total darkness period. So your tv and room lights would cause issues.
The only lights I have on at night is my monitor and like a pink led behind it, will that be ok ?
Depends on how bright and if it right in front of the cham cage.
Its fairly close and there not bright i keep them at like 50 percent and my chair is in front of the cage so I think it should block most of the light
You can always use a black out curtain on the front door of the cage at night when your up.
(Emphasis mine) Might they actually hear more than we think?
My point was that many sources cite the 200-600Hz, but—for whatever reason—never mention that they still hear in the 100-10KHz range, albeit not well. Vibration can certainly be measured/detected in those ranges.
Don't have my medical dictionary handy (busy with the other project
but they're all odd little critters. 
Such diversity, yet so many similarities. 
very true though.
