Characteristic:

• - We can have several boards and easily change them, and special frames perfectly hold the board against the wall. 
• - The board can also be used without frames, e.g. on a table or on the floor
• - Hearing is an important sense in our lives, thanks to this sense we talk to other people, listen to birds singing or dog barking
• - when children touch any scene on the blackboard, they will hear the appropriate sound
•  - there are also high-pitched and low-pitched sound buttons on the board - when looking at the wave charts, children can hear the difference between them
• - the board also explains  how sound travels through the air in the form of waves,  our ears pick up the sound waves and then send the vibrations as signals to the brain
• - there is also a  transparent tube on the board  to show children how the sound travels in the air - every time we turn on the sound on the blackboard, the balls inside the tube should move differently - the  balls vibrate when sound waves pass through them
• - thanks to the blackboard, children  can "see" the transmission of sound waves
• - the board also explains that the sound can vary in volume and we  need to protect our ears when the surroundings are too noisy
• -  batteries required for operation
