The PulsarSafeEar wall-mounted noise-activated system has been designed to assist a teacher keep control of general noise levels in a classroom, corridor or revision room using a visual stimulus.
As the noise level increases beyond a pre-set level of what is deemed acceptable, the noise-activated system wakes and flashes a warning message with a safety graphic to prompt students to take remedial action.
This is what the PulsarSafeEar noise-activated system looks like at rest:
The device is very light and weighs 1.3lbs or 0.6kg only. You can add to it up to 3 additional boards via a simple cable to cover an area of up to 30 meters. Ideal for use in a corridor leading to an exam room.
The device uses high intensity adjustable white LED technology for high visual impact and a long operating life.
Essentially, PulsarSafeEar is a noise level meter with a microphone located at the top end of its back that captures sound from the ambient environment. You can choose a trigger level which can be anything from 40 decibels [dB(A)] to 114 decibels [dB(A)]. The device can be set up so that the warning disappear quickly or remains illuminated for up to 30 seconds after the noise level has gone down below the trigger level. Should you want to, the device can be upgraded so that it becomes a data logging unit to record noise levels over long periods of time.
Although this tool has a number of applications outside classroom management, it is an easy and engaging way to monitor noise levels. Ask students to try to keep the board blank as much as they can, and maybe reward them by allowing them to clap and be noisy on their way out of class to activate it!
We hope this article has given you a good basic overview of how a PulsarSafeEar noise-activated warning system could help you create a quieter classroom.
