Chapter 2: Algorithm of Actions + Physics of Sound 

⚛ School's Curriculum / Program Layout and Physics of Sound

⚛ Additional Information


Algorithm of Actions is Modular Sound Synthesis School curriculum and about it one can learn here. The video content of this chapter refers to second part of the article called "Physics Of Sound".


⚛ The following is a transcript of the narration:



✸ The Physics of Sound. 

✸ All sounds are waveforms.

✸ Sound travels through the air in the form of pressure waves.

✸ Pressure waves travel out words in all directions forming expanding spheres that travel at the speed of sound. 

✸ Pressure waves are measured in Hertz and decibel.

✸ Each waveform shape can be considered to have its own set of harmonics.

✸ Human being can perceive a range of pressure waves between 20 Hz - 20 kHz.. 

✸ Human ear systems detect the following characteristics of sound.

✸ Pitch. 

✸ Sound consists of repeatings waveforms and the frequency of repetition is measured in Hertz.

✸ Timbre.

✸ Changing the shape of the repeating waveform can give the note a different tone. 

✸ Dynamics.

✸ The degrees of loudness or softness in music are called it's dynamics, measured in decibels.

✸ Changer over time. 

✸ The pitch, the timbre and the level can all change during the course of the sound.
