Equivalent Sound Level is formulated in terms of the equivalent steady noise level which in a stated period of time would contain the same noise energy as the time-varying noise during the same time period.
The mathematical definition of Leq for an interval defined as occupying the period between two points in time t1 and t2 is:
where p(t) is the time varying sound pressure and po is a reference pressure taken as 20 micropascals.
The concept of Equivalent Sound Level was developed in both the United States and Germany over a period of years. Equivalent level was used in the 1957 original Air Force Planning Guide for noise from aircraft operations, A-6 as well as in the 1955 report A-7 on criteria for short-time exposure of personnel to high intensity jet aircraft noise, which was the forerunner of the 1956 Air Force Regulation A-8 on "Hazardous Noise Exposure". A more recent application is the development of CNEL (Community Noise Equivalent Level) measure for describing the noise environment of airports. This measure, contained in the Noise Standards, Title 4, Subchapter 6, of the California Administrative Code (1970) is based upon a summation of Leq over a 24-hour period with weightings for exposure during evening and night periods
The Equivalent Noise Level was introduced in 1965 in Germany as a rating specifically to evaluate the impact of aircraft noise upon the neighbors of airports. A-9 It was almost immediately recognized in Austria as appropriate for evaluating the impact of street traffic noise in dwellings A-10 and in schoolrooms. A-11 It has been embodied in the National Test Standards of both East Germany A-12 and West Germany A-13 for rating the subjective effects of fluctuating noises of all kinds, such as from street and road traffic, rail traffic, canal and river ship traffic, aircraft, industrial operations (including the noise from individual machines), sports stadiums, playgrounds, etc. It is the rating used in both the East German A-14 and West German A-15 standard guidelines for city planning. It was the rating that proved to correlate best with subjective response in the large Swedish traffic noise survey of 1966-67. It has come into such general use in Sweden for rating noise exposure that commercial instrumentation is currently available for measuring Leq directly; the lightweight unit is small enough to be held in one hand and can be operated either from batteries or an electrical outlet.
