Continuous White Noise to Reduce Sleep
Latency and Night Wakings in College
Students
LeAnne M. Forquer, Ph.D, C. Merle Johnson, Ph.D.
White noise (sound covering the entire range of human hearing from 20-20,000 hertz)
was investigated to promote sleep in college students. Four college students were
provided white noise generators and instructed to use them all night between 60 and
75 decibels (dB) for one month. A multiple baseline design across participants design
measured sleep latency and night wakings during each night at baseline, treatment,
and follow-up. All students showed a decrease in both sleep latency and night wakings
during treatment; however one�s night wakings returned after white noise was
discontinued at a one month follow-up and three of the four returned at a second
follow-up the next semester. All were comfortable with white noise and would
recommend it to other students with sleep problems. White noise reduced sleep
problems in college students which supports its use as a non-pharmacological
alternative to promote sleep. Like medication it appears to only be effective when
administered.
