Description

The BabbleGuard - a beautifully simple solution to encourage young children or students to keep the classroom noise at a comfortable level, promoting concentration listening and learning.

Designed and made in the UK by Connevans, the BabbleGuard is an attractive and modern LED bar, with a sophisticated sound sensor, which will vary its colour using the traffic light pattern of green, amber and red to reflect the level of sound in the classroom.

The BabbleGuard can be used in a wide range of learning environments and is quick to set up and easy to use.

Key Advantages:

  • Attractive traffic light coloured light bar
  • Easy access to adjustable sensitivity control so you can change the trigger point for different types of lesson
  • Optional warning sound when light goes to red
  • Easy to install - supplied with sticky pads and screws and can be mounted horizontally or vertically, on any wall
  • Bright, clear and easy to see LEDs but not distracting

The BabbleGuard can be used by teachers as part of general classroom discipline to encourage children to self-regulate their noise level. Good classroom acoustics are crucial for a pupil's ability to hear, listen and learn.

Universally applicable, if you have children with special educational needs or a hearing impairment in your class, the level of background noise doubly important.

The BabbleGuard is quick and easy to install, either vertically or horizontally using the supplied sticky pads or screw fixing brackets. We recommend over or alongside the whiteboard, but anywhere where both the teacher and the class can see it easily. It is made from high quality LEDs, giving a really pleasing light which is relaxing and easy to look at for long periods.

Although it is aimed at use in education, the BabbleGuard is also ideal for environments such as libraries or call centres - anywhere where you need people to be aware of the background noise level.
