can hear very low frequency infrasonic

CAT

Thirty-two individual muscles in each ear allow for a manner of directional hearing: a cat can move each ear independently of the other. Because of this mobility, a cat can move its body in one direction and point its ears in another direction.

貓與人類對低頻的聲音有類似的靈敏度，人類除了極少數的調音師能聽到20 kHz以上的高頻的聲音，貓在高頻則可達64kHz，比人類要高1.6個八度音，甚至比狗要高1個八度。

貓的每隻耳朵都有32條獨立的肌肉控制耳殼轉動，因此兩隻耳朵可以單獨的朝向不同的音源轉動，使其在向獵物移動時仍舊能對周遭的其他音源保持直接的接觸。

我估係大象
大象的聽覺非常靈敏,能利用次聲波(即低頻率聲波)進行長途通訊,大象能夠發出低於20赫茲的聲音,可以與大約10公里以外的其他象群交談,連人類聽不到的頻率也聽得到.
