The Sound Alert™ monaural jackbox visibly signals to students and teachers when the jackbox volume is louder than the American Speech-Language-Hearing Association's recommended 85dB level.
When the volume that's played through the jackbox exceeds 85 decibels, a bright red warning light turns on, alerting both the teacher and students about an unsafe sound level requiring adjustment. Having an appropriate volume level pointed out will help teachers and students learn safe and lifelong listening practices, beginning in the classroom, learning center, and school library.
The durable Sound Alert jackbox jackbox is ideal for listening centers, ELL and ELD and other language learning activities. It can also be used as a traditional jackbox without charging the battery, but the warning LED feature will not operate. The Sound Alert jackbox conserves its power by shutting off when no audio signal is present for 60 seconds and will power on automatically when there is an audio signal present.
