So this is a short little audio file that I learned about out here and it absolutely blows my mind. Grab yourself a pair of headphones, better quality ones are preferred, and be blown away. Put on those headphones, press play, and close your eyes. Try your best not to move your head even though you'll be tempted to. You must use headphones for this, speakers will not work...so get your asses up lazy people and get some headphones. Click here to go to audio file!
There's another thing that I learned recently that also blew my mind that also has to do with how our brains work. So sound frequency is measured in this thing called Hertz (Hz), the lower the number the lower the sound is. Humans can hear 20Hz to 20,000Hz (although most adults hear approx. 30Hz to 16,000Hz). Music pretty much covers that entire spectrum and bass is very prevalent around the 100Hz mark. However, those little speakers we are always listening through, you know the one's you stick in your ears? They are completely incapable of reproducing low frequencies...bass and low sounds in music do not play through small speakers. And yet we hear them...how? God made our brains pretty amazing you see, allllll the way back when he first created us he was like "these little buggers way down the line are going to come up with this crazy concept to record sound and play it back with little things in their ears, but they won't have the ability to play back bass in them. So I'll just go ahead and give em all a little helping hand." So here's what He did. Each sound is made of a bunch of frequencies put together (called overtones) and the lowest one is the one we 'hear'. Our brains are capable of recreating these low frequencies by calculating from all the other higher frequencies present what the bottom or 'root' note is. This is what you're "hearing".
There is literally no low frequency sounds being played out of your ear phones or laptop speakers, our brains just fill in the blanks. This is why you can "hear" bass out of these devices but cannot feel them like you can from a sub. Pretty insane eh?
