What does hertz mean in terms of music/sound?
In: Physics
You hear sound thanks to a tiny tiny sheet inside your ear, that goes back and forth when sound from the outside hits it.
This sheet is called the ear drum, since it looks a little like the top of a drum (the part you’re hitting with the drum stick).
A high note (right side of piano) will make the ear drum go back and forth really fast, maybe a thousand times every second. We call this a sound with high frequency.
A low note (left side of piano) will make the ear drum go back and forth really slow, maybe just some tens of times every second. We call this a sound with low frequency.
Hertz is a measurement of frequency. Higher frequency (more Hertz), higher pitch/note. Piano keys on the right side of the board hit strings which vibrate at a higher frequency than the strings to their left.
Hertz is repetitions per second. So you can imagine a sound wave repeating or in terms of your speakers, 1 repetition is the speaker going forward and back that creates the sound. 5hz is 5 back and forths second, 10,00hz is 10,000 of that per second.
