Arescue team is searching for andrew, a geologist who was stranded while conducting research in the mountains of colorado. the team uses electronic listening devices in order to detect any shouts for . the sound waves from his shouts reaching the base camp can be approximated by a sinusoidal wave with a frequency f = 500 hz and displacement amplitude a = 1.50×10−8 m , where the sound wave properties are valid at the base camp where the measurements are being made. what sound intensity level will the rescue team measure from the frightened researcher? assume the speed of sound is v=333m/s and the density of air rho = 1.30 kg/m3 .

in the original problem, you were provided specific information about the location of the researcher. how would the resulting sound intensity level be affected if the researcher had been conducting his research along the coastline of british columbia, where the air density is greater? assume that at both locations the sound waves used to model the researcher's yells have the same amplitude, frequency, and propagate at the same speed.
