What Is The Documentary Math: Who Needs It?
Math is not just a subject taught throughout school. Math is used in almost every job, activity, and hobby. In the documentary “Math: Who Needs It?” the main goal is to show the viewers how math is used in almost every job the world has to offer. One point that stuck out in the documentary was the “Rockstar” portion. Music is a big part of my life and many people do not take a moment to think about all the work put behind the process of making a song, creating the instruments, and producing the song (making it sound good). On a page of sheet music there are many various symbols and numbers that a non-musician may not know the meaning of. Most likely the first thing noticed is the wide variety of stick looking drawings with a oval on it, painted

Now sound engineers not only make the song sound clean but they produce the song we will hear on the radio, Spotify, iTunes, etc. They are also the people that travel with the artists and makes sure while they are on stage there are no frequency spikes (which causes the really annoying high pitched sound), and also keeps everything equal so one instrument does not overpower the vocals or other instruments. They also protect everyone's ears at concerts. Yes, concerts usually go 100 dB which is past the “Too Loud” line, but they keep it from going so loud that it causes people to go deaf. Rock concerts range from 100-110 dB, which is very loud but it is still 50-60 dB below instant perforation of the eardrum. They have to use equations that deal with frequency, wavelength, and period. For example: to find the wavelength they would use the equation: L= V/f. V is the velocity of sound and f is the frequency of the sound. These engineers use huge sound boards to equalize and combine separate parts of a song together. Each knob changing a different wavelength/pitch. Making each song …show more content…
Music is a part of just about everyone's life and if there were no sound engineers, skilled piano makers, or mathematics in music it would sound terrible. Humans ability to make and enjoy music is all here because of the people who listened in math class and aspired to do great things. The Earth is full fun activities that are full of math, but not many people know this. They don’t know that math is the reason that they can go to concerts and not go home with popped ear drums or even be able to play
