Lol. "Mice" should be mics. Ah auto correct.

This is ridiculous. First of all I've never heard of frequencies being expressed in .whatever as far as sound goes. If it was 393hz okay. There is no way the human voice can produce 39hz. In fact at 20hz you're not actually hearing it but feeling it. The human range of hearing is more like 16 - 18khz to 30hz or so. The older you get the less you hear of the upper range. I could go on and on about how stupid this is but alas I digress. Also to the person that said audio engineers reverse speakers to capture bass drums. While you could do that it would be completely retarded as it wouldn't make a very good quality mic and there are plenty of fantastic mice that can capture low frequencies. Secondly a bass drum really doesn't produce ultra low frequencies. The bass player fills in the lower end.
