Hearing is a lot easier to lose than to get back. Classrooms today all have some sort of setup for students to listen to programming. Music is often the format that will always end up a little too loud.
Hamilton Electronics, a leader in A/V products for education, has an excellent headphone that allows the teacher and/or parent to monitor the sound level visually. The HA-31 Guardian Headset has lights built in the the earpieces which light up as the sound level increases. When the level is higher than the recommended levels a red light turns on, telling the supervisor it is time to have the listener turn down.
This headphone is popular with schools in the labs and also for home use; the two indicator lights can easily be seen across the room.
