I am a dental hygienist and bought these for when I use my cavitron unit for long periods of time.<br />I have small ears, so they don't fit the greatest (fall out of my ears sometimes), but they do block out the high pitch sound of the cavitron and loud suction still! It is somewhat hard to talk to patients, though - you don't know how loud you are talking and sometimes can't hear what people are saying. They do actually do their job of eliminating the high pitch noises, so that is the best part!
