ACOUSTIC ECOLOGY (ecoacoustics/ soundscape studies): The relationship between livings beings and their environment, mediated through sound. Specifically it is a discipline that analyzes how we interpret, and are affected by natural and artificial sounds around us.

Among the expanded expressions of acoustic ecology areincreasing attention to the sonic impacts of road and airport construction, widespread networks of “phonographers” exploring the world through sound, the broadening of bioacoustics (the use of sound by animals) to consider the subjective and objective responses of animals to human noise, including increasing use of the idea of “acoustic ecology” in the literature, and a popular in the effects of human noise on animals, with ocean noise capturing the most attention.

GEOPHONY: Soundscape sources that are generated by non-biological natural sources such as wind in the trees, water in a stream or waves at the ocean, and earth movement, the first sounds heard on earth by any sound-sentient organism. (DANIEL)

COLOR: Color is a characteristic of a “meaningless” noise signal describing its power spectrum over time. Color is a way of describing sound without a distinct tone or pitch. The association of certain dB/freq patterns with visual color names is somewhat arbitrary and the noise does not have a connection with the visual color. Some noise colors include white (equal power in any given bandwidth), pink, brown, blue, violet, and grey. (RAINA)

TEXTURE: Texture of sound is a way of describing its overall quality in terms of the relationship of elements. In traditional music composition texture refers to the way melodic, harmonic and rhythmic components combine. This quality is often referred to in terms of density- for example a single melody would be understood as “thin” whereas a composition with multiple melodies and rhythmic components would be referred to as “thick.” Within musical composition there are various described ‘textures,” including harmony (two different pitches heard simultaneously), monophony (a single melody alone), polyphony (several melodies at the same time) and homophony (chordal harmony). (RAINA)
