Ultrasonic Sound Detector
Prepare your ears for sounds that you've never heard before! This detector picks up sounds that our human ear cannot normally hear. It then projects the sounds so we can hear them.
Listen to dogs and bats, hear computer screens and fluorescent lights, discover the sounds of fizzy bubbles and much more. This ultrasonic detector from Discovery Kids expands our world!
