I thought it wouldn’t make sense at first, but thinking about it more I think it does. Sound can’t travel through the walls of the bug. It probably echos inside it, but there’s not a lot of air around their neck for it to come out through, and sound doesn’t travel well between gases and solids, so most of the sound would be absorbed. It wouldn’t be perfect, but it would make it a lot quieter.
