Grey noise spectrum The result is that grey noise contains all frequencies with equal loudness , as opposed to white noise , which contains all frequencies with equal energy . The difference between the two is the result of psychoacoustics , more specifically the fact that the human hearing is more sensitive to some frequencies than others.
In music, "noise" has been variously described as unpitched, indeterminate, uncontrolled, convoluted, unmelodic, loud, otherwise unmusical, or unwanted sound, or simply as sound in general. The exact definition is often a matter of both cultural norms and personal tastes.
Noise that has a frequency spectrum of predominantly zero power level over all frequencies except for a few narrow bands or spikes. Note: An example of black noise in a facsimile transmission system is the spectrum that might be obtained when scanning a black area in which there are a few random white spots. Thus, in the time domain, a few ...
According to Danish noise and music theorist Torben Sangild, one single definition of noise in music is not possible. Sangild instead provides three basic definitions of noise: a musical acoustics definition, a second communicative definition based on distortion or disturbance of a communicative signal, and a third definition based in subjectivity (what is noise to one person can be meaningful ...
Sound quality is typically an assessment of the accuracy, fidelity, or intelligibility of audio output from an electronic device. Quality can be measured objectively, such as when tools are used to gauge the accuracy with which the device reproduces an original sound; or it can be measured subjectively, such as when human listeners respond to ...

The big three in sleep sounds are white noise, brown noise, and pink noise, but there are many other noise types, including purple noise, gray noise, and even black noise (a.k.a. good ol ...
