Betzold Lärmlicht

Noise recorder for classes and groups: The Betzold noise light is a smart solution for keeping an eye on the noise level in classrooms or group rooms. With its luminous 360-degree cover, it changes colour from green to yellow to red to indicate whether the noise level remains within the acceptable range. Thanks to its compact design with a height of 17.5 cm and a diameter of 12 cm, it is easy to transport and can be used flexibly.

Customised adaptation to any room: With four adjustable sensitivity levels, the noise light can be adapted to different room sizes and age groups. An additional alarm tone can be activated as acoustic support to draw attention. For even more flexibility, the sound can be completely deactivated if required.

Compact and sustainable: The integrated rechargeable lithium battery makes the noise light mobile and ensures up to 8 hours of use. It is charged via a modern USB-C connection and does not require a mains adapter, which reduces unnecessary electrical waste.

Promoting self-control: The visual feedback of the noise light helps children to control their noise level independently. By actively paying attention to the colours, they develop an awareness of their surroundings and learn to be considerate of others. This not only creates a quieter space, but also promotes important social skills.

Creating an optimal learning atmosphere: Teachers and educators benefit from a harmonious environment in which everyone can concentrate. The Betzold noise light helps to create an atmosphere characterised by consideration - an important step towards pleasant interaction.
