PPT-Aircraft Noise Exposure Contour Update

Overview FAA recommends updating every 57 years Last official noise exposure map is from 2001 Worked with Ricondo and Associates to complete the Noise Exposure Map Noise exposure contours for daynight average DNL sound levels 55 60 65 70 and 75. A line that creates boundaries that separates one area from another. They define the edges and surface ridges of objects and figures.. . Contour line drawings are like coloring book pages. No Value (light and dark shadows and highlights). What is a contour . interval?. The difference . in elevation between two contour lines that are side by side.. Sometimes the map tells you! . How can we determine the contour interval?. How can we determine the contour interval?. a ridge. a valley. g. oing uphill. closer . contours. = steeper slope. contours farther apart = shallower slope. Imagine that the red line represents a geologic contact of some sort. Given that it doesn’t parallel contours we know it isn’t horizontal, and given that it doesn’t cut straight across contours we know it isn’t vertical. Can we tell something about its orientation? .

Let’s make a topographic profile from A to C, passing through the top of the bank at B. It will help us see how steep the East Flower Garden Bank is along that line. To make a topographic profile you will need:. Gulshan. . Kumar. School of Fisheries. Contour survey. A contour or a contour line may be defined as the line of intersection of a level surface with the surface of ground. . This . means every . point on a contour line has the same altitude .

Noise has become a very important stress factor in recent time.. th. year. The Environmental Effects of Noise. 5.1 The Ear . . When a sound wave enters the ear, it sets the eardrum into oscillation, which in turn causes oscillation of the three tiny bones in the middle ear called the ossicles, Fig.5.1. This oscillation is finally transmitted to the fluid-filled inner ear, the motion of the fluid disturbs hair cells within the inner ear, which transmit nerve impulses to the brain with the information that a sound is present.
