Studies on the costs of soundproofing of existing structures and new structures, soundproofing requirements for new buildings, and the reaction of property owners are discussed with reference to example cases. Comments are made on the significance of sound levels, and it is observed that if land development cost does not decrease in proportion to the density loss, the offset must occur in either decreased net to land or lowered profit ratios. The most rapid analysis of these perimeters is obtained via the computer, which is the most satisfactory tool provided that the program has the required flexibility. In the area of government controls, appraisers should be cautious in accepting local agency officials opinions regarding the amount of control they can exercise. The fact that a property or areas is situated near a noise source is not prima facie evidence of loss in value, and the appraiser will have to find valid methods of accurately measuring value loss. Particular attention should be given to the ambient noise levels in affected areas since response to aircraft or any noise source may be effectively diluted when people are generally used to unusually high noise levels. Similar close examination of sales data is required in most appraisals.
