Colors of sounds can each affect your brain differently. Find out which noise is best for sleep: white vs. brown vs. pink.
Annoyance effects of noise are minimally affected by demographics, but fear of the noise source and sensitivity to noise both strongly affect the 'annoyance' of a noise. [42] Sound levels as low as 40 dB(A) can generate noise complaints [43] and the lower threshold for noise producing sleep disturbance is 45 dB(A) or lower. [44]
The Environmental Noise Directive (END) was created in the European Union to provide guidelines, laws, and standards in the management of environmental noise. The END has created noise mapping, noise action plans, and quiet areas to control environmental noise and the negative effects it can have on individuals. [22]
Highway noise is today less affected by motor type, since the effects in higher speed are aerodynamic and tire noise related. Other contributions to the reduction of noise at the source are: improved tire tread designs for trucks in the 1970s, better shielding of diesel stacks in the 1980s, and local vehicle regulation of unmuffled vehicles.

Infants should sleep on flat surfaces on their backs, free of weighted swaddles and with their caregivers in the same room — but not on the same bed, according to new guidelines on safe sleeping ...
The effects of sleep deprivation vary substantially from person to person. [9] [10] Sleep deprivation and cumulative fatigue effects describe how individuals who fail to have an adequate period of sleep (7–8 hours in 24 hours) or who have been awake longer than the conventional 16–17 hours will suffer sleep deprivation. A sleep deficit ...
White noise machines and other white noise sources are sold as privacy enhancers and sleep aids (see music and sleep) and to mask tinnitus. [11] The Marpac Sleep-Mate was the first domestic use white noise machine built in 1962 by traveling salesman Jim Buckwalter. [ 12 ]
