My BP is in my room (it wasn't the quietest room but my apartment has no central air and we have our A/C running in our living room almost every night so we figured the room would be a better choice).

Me and the husband watch movies all the time and both put the volume up pretty high and so far she doesn't seem bothered by it. She even is active at night whether we have the TV light on or not so hopefully your snake won't be bothered by it either
