But as the number of painted caves discovered grew,
但隨著越來越多的壁畫石洞被發現
it became clear that art and music came into the world together,
人們逐漸認識到繪畫和音樂是同時來到世間的
for musical instruments were found.
因為石洞中還發現了樂器
Animal horns...
動物角
flutes made from bones of vultures,
禿鷲骨頭做成的笛子
and even more hauntingly, bullroarers,
還有更令人難以忘懷的 吼板
a piece of wood tied to a rope spun round the head
把一塊木頭綁在繩子上 在頭頂旋轉
that makes this strange whooping sound.
從而發出奇怪的吼叫聲
Recent experiments with these instruments have suggested
近期關于這些樂器的實驗表明
that the proximity of painting and music was not accidental,
繪畫和音樂的相似性并非偶然
that they were connected elements in sacred rituals.
它們是神圣儀式中相關聯的元素
I'm using software to test the acoustics in the space.
我正在用軟件來測試這個空間的聲音特性
So we generate this swept sine wave
我們生成這個正弦掃頻信號
and we use that to capture the acoustic of the cave.
然后利用它來測定洞穴的聲音特性
And we can look for relationships between sound and paintings.
接著我們可以來尋找聲音和繪畫之間的關系
