Every note on a instrument corresponds to a certain frequency, Ex: A2 = 440Hz. Every instrument an microphones have a set dynamic range the produce. But in practice sound is represented as wave for easier manipulation.įrequency, frequency is how far apart are the peeks in the sound wave, the closer the higher the frequency, these translate directly into music notes.
a sound wave that propagates faster is perceived as a louder sound. Interesting enough sound waves amplitude are in fact (counter intuitively) a longitudinal wave, like sound pressure, i.e. It has a certain speed of propagation and is also connected to our sense of space, because of surface reflections (reverb, delay).Īmplitude, how high (and/or low) are the sound wave curve peaks. Propagation, is the sound moving around from point A to point B. Touching still water creates (mechanical) waves, sound is the equivalent on air, sound is about agitating still air, generating a (mechanical) wave that propagates through air when when reaches our ears is perceived as sound.Ī Speaker works by pushing air with its cone at a specific vibration. Sound is a mechanical wave that is an oscillation of pressure transmitted through some medium (like air or water), composed of frequencies which are within the range of hearing.
