Physics of Music

The fluid behavior of sound waves only occurs when there is medium. Through this, there should be air as there is sound. In the case of sound waves emitted from instruments and received by listeners, the instrument must excite the surrounding air and diffuse its energy into the air in the form of compression / longitudinal waves. When the listener receives it, the waves pulsate the tympanic membrane with the same variable frequency as it was emitted. The instrument shakes, the instrument gets a sound, the air is excited by the vibration and vibrates.

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. Sonic waves are not like waves on the ocean or stretched ropes. Take the tuning fork (You have a tuning fork.)

In this part of music and brain, we will explore why certain sounds cause physical reactions. Regardless of whether it is chill, heartbeat, relaxation or tears, most of us experience some physical reaction to music at some stage of our lives. According to the studies I encountered, there are many very interesting reasons why this may happen. "If you like, concerts will influence us - that's what we like!" So according to this logic, the type of music you like influences your response to it Let's see. In order to avoid this potential bias in researching the influence of music, you can study babies exposed to music (as they do not form preferences yet). Studies by teachers at the University of Tel Aviv show that 30 minutes of live music broadcasting in a neonatal intensive care unit for premature babies improves short-term stress on physiology and behavior.

As the scientific method progressed in the 19th century, music was investigated about the possibility of physiological change. The first published music therapy research appeared in 1789 and was called "Physical consideration of music" (author is unknown). The paper on subjects published by American medical researchers includes the paper by Edwin Augustus Atlay in 1804 and the second paper by Samuel Matthews in 1806. Under the guidance of American doctor Benjamin Rush Atlee and Mathews studied as a supporter of music clinical application. In the 19th century, music therapy experiments were held at the Blackwell's Island Asylum facility in New York.
