PsstBee – Noise Light

Hendrik Lang

About this app

PsstBee is a smart and interactive noise traffic light designed for schools and daycare environments. It helps visualize the current noise level in the room and encourages children to develop awareness for a calm and respectful environment.

Through a simple color system – green for quiet, yellow for moderate, and red for loud – PsstBee makes noise levels easy to understand, even for young children. When the noise level becomes too high, the app can trigger a visual and acoustic alert to remind the group to reduce their volume.

PsstBee is highly adaptable: you can customize the decibel thresholds according to your room size, activity type, or age group. This makes it suitable for classrooms, group times, reading corners, play areas, therapy rooms, and more.

Key Features

• Clear color-based display of noise levels (green / yellow / red)
• Customizable dB thresholds
• Visual and optional acoustic alerts
• Real-time noise monitoring
• Tracking of peak values and loud events
• Designed for classrooms and group activities

Why PsstBee?

Traditional “be quiet” reminders often interrupt learning. PsstBee makes silence visual, intuitive, and supportive – without constant verbal feedback. It empowers children to self-correct and helps educators focus on teaching rather than noise management.

Ideal for:

• Schools & classrooms
• Kindergartens & daycare
• Special education and therapy settings
• Libraries & reading corners
• Group learning activities

PsstBee promotes well-being, focus, and healthy sound environments. Reduce stress, protect hearing, and make classroom management easier – with a friendly helper that children understand at a glance.
