The Physics of Music

When the sound spreads outward, it "spreads" over a wider area. The minimum sound intensity (called hearing threshold) that can be detected with the human ear is about 10 -2 W / m 2. At an intensity of about 1 W / m 2, the sound will hurt at the ear. The frequency of a sound wave that looks like a pitch is the amount of compression (or sparse) that passes through a fixed point per unit time. The frequency that can be heard by the human ear is in the range of about 20 Hz to 20 kHz. Intensity is the average energy flow per unit time in a particular media area and is related to volume (Shipman-Wilson-Higgins, 2013).

Resonance and sound ... Because physics and music are media of music, most of the physics of music is physics of sound. It is important to remember that sound waves are compression waves. You can imitate the compression wave by stretching the tights (you have tight feet?) And finally tap the coil with your fingers. Sound waves are not like waves drawn by stretching the waves of the ocean and ropes. Take a tuning fork (You have a tuning fork, do not you?) Then hit it on the knee.

Let's start with an abstract connection. The "music math" website you go with google is often about physics. Sound is a special type of energy that travels in the form of pressure waves through air at a specific frequency that you hear in the human ear. To say that music is mathematics is the same as saying that car repair is mathematics or football is mathematics - they are all in the form of engineering or physics. However, musicians, repairers, quarterback do not use Fourier analysis or power system for trading.

I would like to repeat that music is a product. This is something to sell. But it is one of the most unique and complex products to sell. It is both intellectual and material. When buying music, consumers get two things: touching a series of ideas conceived by artists and accessing physical products. However, the digital download has changed the game. At any moment music consumers may repeat the artist's work on several platforms and devices. Based on previous work experience, through the accessibility and mobility of digital downloads, listeners have more opportunities to judge work as desirable or inappropriate. This will not change the satisfaction of the previously published music experience. Unfortunately, consuming music as a product does not lead to repeated purchases of the same work in the digital age.
