Health Effects of Noise on Children

"Calling noise a nuisance is like calling smog an inconvenience," said Dr. William H. Stewart, MD, former US Surgeon General. "Noise must be considered a hazard to the health of people everywhere."
Studies and research conducted by the American Academy of Pediatrics, the NIPH, the Department of Public Health and the National Noise Center, the National Center for Environmental Health, and the World Health Organization (WHO), unanimously list the harmful effects of noise as multiple, far-reaching and, in some cases, irreversible. Those can include hearing loss or impairment, interference with speech communication, disturbance of rest and sleep, mental-health and performance effects, effects on residential behavior and annoyance, performance reduction as well as interference with intended activities. Studies are also underway to corroborate a theory potentially linking noise to another serious condition, Menieres Disease, which causes fluctuating hearing loss, tinnitus (ringing in the ear), bouts of vertigo, and headaches. Because noise causes stress, it elicits an increased adrenaline reaction, affecting the cardiovascular system, changing heart rate, and causing a rise in blood pressure.

Drs. Maxwell and Evans list the most important physiological effect of chronic noise exposure as being elevated blood pressure levels, which "appear to continue this pattern into adulthood, thereby increasing the risk for cardiovascular disease." Motivational effects render children "more vulnerable to learned helplessness," while cognitive effects impair memory, may cause attention deficits in children exposed to chronic noise levels, and may negatively affect academic achievement, particularly reading," according to the duo.

Noise Environment and Children's Learning

According to the Science Daily News Release, researchers at The Ohio State University have found that, "The acoustics of many classrooms are poor enough to make listening and learning difficult for children." The findings point to the fact that children's learning ability and speech development is hindered when they can't hear well in the classroom.

Many Classrooms Have Bad Acoustics That Inhibit Learning

ScienceDaily (Dec. 24, 1999) — COLUMBUS, Ohio -- Researchers at Ohio State University have found that the acoustics of many classrooms are poor enough to make listening and learning difficult for children.


The study of 32 classrooms in central Ohio primary schools found that only two met the standards recommended by the American Speech-Language-Hearing Association (ASHA).
“This is probably the most extensive acoustical study of classrooms ever,” said Lawrence Feth, professor of speech and hearing science at Ohio State.
