Control Noise Level Or Timed Events With This Dual-Purpose Device
Shaped like an hour glass, this electronic timer doubles as a noise meter. It can be seen and heard from anywhere in your classroom or even in an auditorium. In timer mode, the light gradually empties from the hour glass, giving students a visual cue of how much time remains for tests, games, and other events. The light turns red as time runs out, and the device gives a one-minute warning with sound and lights before signaling time's up. Flip the switch to noise-control mode and select one of six settings. Rows of lights indicate the noise level in the room. When the noise reaches the top range for the selected level, the device gives a warning, signaling the room to quiet down. Requires four C batteries or an AC adapter (not included).
