The Guardian Addresses the Early Childhood and Special Education needs identified by No Child Left Behind. How can you tell if the volume in your students' headphones too loud for safe listening"
Hearing impairment in school age children is increasing, and continues to be overlooked as teachers, therapists, and parents seek answers to children's learning disabilities and developmental delays.
Now you can have SAFE SOUND with Hamilton's Guardian wired headphone, with SLM (Sound Level Monitor) Technology. The Guardian headphone has LED's that allow you to see the level of your students volume from across the room.
The green LED indicates a safe listening level for your students that won't harm their ears. The red LED when lit alerts you that the child may have a hearing problem or is at risk of causing irreversible damage to their ears.
Comes with AC adapter to charge internal battery.
One (1) year warranty.
