Effects of jet aircraft noise on mental hospital admissions.

We study, in the vicinity of Los Angeles International Airport, the effect of jet noise on mental hospital admissions. The maximum noise area (where the maximum fly-over noise exceeds 90 dBA) shows a 29% increase in admissions over those of a corresponding control area, as like the target area as possible, except that in the control area jet noise is not a dominant factor. The results are similar to those of a previous study carried out near Heathrow Airport.
