Of these agencies, the Educational Facilities Laboratory, New York, indicated an interest in assisting the school district by providing consultant help to assess the severity of the problem and begin exploring alternative solutions. A small grant to the Highline District has been made by E.F.L. with the express purpose of further research into the alleviation of the noise problem through construction alternatives. This study—to be completed by August of 1973-includes the following steps:

A. Simultaneous measurement within and without the classroom during numerous flyovers.

B. Measurement of the period of time during which sound levels in dBA exceeded predetermined, tolerable levels in order to estimate the amount of time lost due to inability to communicate.

C. Establishment of a tolerance noise criteria within the classroom, based upon the special noise climate requirement of each classroom.

D. Calculation of the noise reduction from inside to outside of building.

E. Preparation of plans modifying the existing construction (by an architectural firm) which would improve the sound isolation of the exterior partition/roof system and meet varying degrees of noise reduction criteria.

F. Estimates of construction costs based upon those varying degrees of acoustical satisfaction which different classrooms required.

This was an extensive research project funded by a single school district. It was conceived and executed in the desperate hope of finding a simple, or at least economically feasible, solution to the noise problem. In the final analysis, however, the Highline School District found that the costs of repair which would meet even compromise criteria far exceed their ability to obtain requisite funding.

The current study, funded by Educational Facilities Laboratory, includes a physiological and behavioral assessment of the effects of jet noise on students. This portion of the study includes the measurement of hearing level, blood pressure, emotional responses, vocal behavior, and attitudes as manifested by students. Results will be reported as they become available.

A search of the literature was conducted, which pointed up the severity of the problem of noise pollution. The October 11, 1971, issue of Time magazine (pages 91 states that "... the din occasionally reaches 90 decibels, enough to cause permanent damage to hearing in 10% of the people who might be exposed to it for eight hours a day.” This reference was made to office buildings in the Loop area of Chicago as particularly demonstrating the severity of the problem. The staff of the Highline District is particularly concerned about this statement, as the school children in several of the Highline schools are exposed to sound levels in excess of 100 decibels.

Although the literature of late portrays the severity of the problem, there is little available information on remediation, particularly in the educational arena. With the exception of demolition or abandonment of buildings, educators have not at this point begun to scientifically study the problem.

The Highline School District has concluded, after several years of intensive study, that:
