Pythagoras observed that when the lengths of vibrating strings are ratios of integers such as 2 to 3, 3-4, the tones produced will be harmonics.
Aristotle wrote his de Anima that impacts, blows, or impingements are required to produce sound.
Isaac Newton made a significant contribution to the theory of acoustics in his Principia by deciphering the relationship between the spped of sound and the gas it is in.
The AMPLITUDE of a periodic wave is a measure of its change over a single period that indicates deviation from the point of equilibrium.
Low frequency build up describes a particular type of constructive INTERFERENCE in the low frequency spectrum.
MIX POSITION= point space where an engineer is most likely to be sitting for monitoring and mixing.
Standing Waves are waves that remain in a constant position!
ABSORBERS= are any materials or structures that is naturally or designed to be acoustically unreflective!
DIFFRACTION= describes the bending of waves around small obstacles and the propagation and spreading through openings and around corners.
Diffusion= describes the tendency for sounds to spread out evenly in a consistent medium.
Frequency= is measured in Hertz Hz, Hz= 1 cycle per sound!
Interference= can be constructive or deconstructive depending on the phase relationship of the offending waves.
ROOM MODES= are the resonant freqs of an enclosed structure!
Longer Wavelengths will require larger absorption materials/ constructs.
DIFFUSER= will cause sound energy to be radiated in many directions.
