There is also the Scottish Small Pipes. Much smaller and quieter than the Great Highland Pipe (which is also played by the Irish, btw). They did fall out of regular use at one point and have been revived in more recent times.
Kathryn Tickell had a Gallician Piper as a guest at a concert I was at some years ago and you're right, they're seriously loud. Some regions of France have traditional pipes which are pretty loud.
