Acoustic theory is a scientific field that relates to the description of sound waves. It derives from fluid dynamics . See acoustics for the engineering approach.
Acoustical engineers concerned with environmental acoustics face the challenge of measuring or predicting likely noise levels, determining an acceptable level for that noise, and determining how the noise can be controlled. Environmental acoustics work is usually done by acoustic consultants or those working in environmental health. [13]

Musical acoustics – study of the physics of acoustic instruments; the audio signal processing used in electronic music; the computer analysis of music and composition, and the perception and cognitive neuroscience of music. [10] Psychoacoustics – study of how humans respond to sounds. [11]
Hermann von Helmholtz elaborated the law into what is often today known as Ohm's acoustic law, by adding that the quality of a tone depends solely on the number and relative strength of its partial simple tones, and not on their relative phases. [4] [5] Helmholtz championed the law in opposition to contrary evidence expounded by August Seebeck. [6]

[4] [5] In Ohm's acoustic law, later further elaborated by Helmholtz, musical tones are perceived as a set of pure tones. The percept of pitch depends on the frequency of the most prominent tone, and the phases of the individual components is discarded. This theory has often been blamed for creating a confusion between pitch, frequency and pure ...
