You have a plethora of options to assist you with you duty..... (pun?). My favorite being the flushing sound that you can use to disguise your  bodies embarrassing sounds. And yes you can control the volume.  Last but not least if you look to the far right you can see a deodorizer, but not just any, it is a "powerful deodorizer". If you get the chance, check out these toilets, they are second to none.
