Sound travels in waves, there are 2 different types of waves direction and indirection, reflection, absorption. You measure the pitch and speed in frequency. low pitches are far apart. High pitches are really close together. Amplitude measure the volume also in decibels.
I knew about like frequencies, but i didn't know that the closer the waves are together the higher the pitch, and the farther apart they are the lower the pitch. I also didn't know that with camera crews they count in the person they are filming because they use the sound bit before they started rolling to edit the sound if they need a pause or something.
Younger americans are losing there hearing at younger ages, over half of hearing lose is is people under the age of 25. Talks about how younger people dont wanna wear hearing aids. There is no cure for hearing loss. Jim from the video says to get your ears checked and dont take any chances.
This really made me think about my decibel exposure, or how loud i listen to my music in my car and my headphones, i will defiantly turn my music down now lol
