A- weighted — a specific weighting of the sound pressure level for the purpose of <br />determining the human response to sound. The specific weighting characteristics and <br />tolerances are those given -in American National Standards Institute S1.4 -1983, Section 5.01. <br />Abando Vehicle -Anv - mnt,,,- ,>em-i ___,_• , <br />Agricultural Land - the areas in Minnesota lying south and west of a line along the <br />following highway right -of -way: starting at the North Dakota border, the line goes east <br />along State Highway 10 to State Highway 23, then follows Highway 23 east to State <br />Highway 95, which it follows to the Wisconsin border.
