Low C, which is two octaves below middle C and the low note on a cello is about 65 Hz with modern tuning of A=440Hz.

Young ears can hear in the range of 20Hz - 20 KHz and there are instruments with a lower range than the cello so I don't think it's correct to say that adjusting this up six octaves moves it into the range audible by human ears. The video comments says 100x speedup so that would be 5000Hz.

Perhaps it would be better to say that it was sped up so that it would sound more like earth wind?
