Masterkidz Wall Elements - Sense of Hearing 牆面遊戲 - 聽覺

Model: ME15839 | Age 3+

聽力－如果沒有我們的耳朵，世界將會變得非常不同！ 我們要用耳朵告訴孩子，我們可以聽別人說話、鳥叫、狗叫聲、流水。 當孩子觸摸面板上的任何場景時，他們都能聽到相應的聲音。 還有高音和低音的聲音按鈕。 孩子們在看聲波圖的同時，可以用耳朵找出它們之間的差異。 我們也向孩子解釋聲音在空氣中以波的形式傳播。 我們的耳朵收集周圍的所有聲波，並將振動作為信號發送到我們的大腦。 我們添加了透明的丙烯酸管，以便向孩子們展示聲音在空氣中的傳播。 每次播放聲音時，孩子都會發現管子中間的泡沫球有不同程度的振動。 當聲波經過時，泡沫球會振動。 例如，當播放雷雨聲時，孩子們可以看到泡沫球在振動。 這是讓孩子「看到」聲波傳播的好主意。 牆板也向孩子解釋聲音可以有不同的幅度（響度），當周圍環境太大時我們需要保護我們的耳朵。

由俄羅斯樺木合板和山毛櫸木 (FSC) 製成。

Hearing - The world would be a very different place without our ears! We want to tell children with our ears, we can listen to other people speaking, bird singing, dog barking and water running. When children touch any of the scenes on the panel, they can hear the corresponding sound. There are also high-pitched and low-pitched sound buttons. While looking at the sound waves diagrams, children can use their ears to find the difference between them. We also explain to children sound travels in waves through the air. Our ears gather up all of the sound waves around us and send the vibrations as signals to our brains. We have added a clear acrylic tube in order to show children sound travels through air. Everytime when a sound is being played, children should find there are different degrees of vibrations on the foam balls sitting at the middle of the tube. The foam balls vibrate when sound waves pass by. For example, when sound of a thunder storm is being played, children can see the foam balls vibrating. This is a good idea to let children "see" the transmission of sound waves. The wall panel also explains to children sound can be of different magnitude (loudness) and we need to protect our ears when the surroundings are too loud.
