This is a crazy new thing that my department head showed me today. See what frequencies you can hear. I can hear all of them until 18 & younger. My boss could only hear up to 30 & younger. Teachers have to watch out for these things because now students' cell phones can be ringing without the teacher even being able to hear it.
