Numerous studies conclude that chronic exposure to loud noise is detrimental to personal health, individual achievement, and general quality of life, often without any awareness of its effects.

These studies link high levels of constant or routinely recurring aircraft noise to:

*  stress-related disorders
*  sleep disturbance
*  increased cardiovascular activity
*  hypertension
*  gastro-intestinal disorders
*  irritability
*  work and learning impairment (particularly in young children, the hearing
   impaired, and those who have special education needs) among other
   other mental and physical problems, including "learned helplessness."
