In psychoacoustics, noise can be categorized as different ‘colors’, which refers to the varying power and spread of noise signals over the spectrum of sound frequencies. White noise contains all frequencies at equal volumes, and pink noise, in which the power spectral density of the sound is inverse to the frequency. Both have been studied for their effects on sleep and relaxation. However, little research exists on the topic of colored noise usage for stress reduction and the effects it may have on the acute stress response.
