But as the number of painted caves discovered grew,

it became clear that art and music came into the world together,

for musical instruments were found.

Animal horns...
动物角
flutes made from bones of vultures,
秃鹫骨头做成的笛子
and even more hauntingly, bullroarers,
还有更令人难以忘怀的 吼板
a piece of wood tied to a rope spun round the head
把一块木头绑在绳子上 在头顶旋转
that makes this strange whooping sound.
从而发出奇怪的吼叫声
Recent experiments with these instruments have suggested

I'm using software to test the acoustics in the space.
我正在用软件来测试这个空间的声音特性
So we generate this swept sine wave
我们生成这个正弦扫频信号
and we use that to capture the acoustic of the cave.
然后利用它来测定洞穴的声音特性
And we can look for relationships between sound and paintings.
接着我们可以来寻找声音和绘画之间的关系
