Not to hijack the OP, but I also work in an office while diapered. I've been here for 14 years, and it is quiet. You can hear the pc case fans running most times, and usually can hear a conversation the next office office over. We have open and enclosed rooms about 7-10 ft square, but no cubicles.
I've worked in the open offices (separated by 4ft walls) and even in an enclosed office for a year while sharing it with a trainee. I now work in that same enclosed office alone. I started off with mid grade diapers like molicare and abena, but also with a plastic diaper cover. They leaked on me too often though (thank goodness for the diaper cover) so I switched to using premium diapers and now use confidry. The plastic pants would wear out fast too though, so I switched to PUL instead.
In 14 years nobody has once noticed.
