ASK YOUR TEACHER With the installation of noise suppression materials, the noise level in an auditorium was reduced from 95 to 81 decibels. The level of sound ß (in decibels) with an intensity of I is B(I) = 10 log10 (I/I0), where Io is an intensity of 10-16 watt per square centimeter, corresponding roughly to the faintest sound that can be heard. Use this information to find the percent decrease in the intensity level of the noise as a result of the installation of these materials. (Round your answer to the nearest percent.) % Need Help?

(a) To appreciate the human ear’s twelve order of magnitude (1012) span from barely audible to the pain threshold, consider the following. Suppose an equivalently dynamic instrument were designed to measure distances. Taking the lower limit of the instrument to be 1.00 mm, what would be the largest distance measurable? (b) To provide a perspective for the human ear’s frequency sensitivity range (audible frequency extremes differ by 103 ), consider a speedometer with a similar speed range. If the speedometer’s maximum speed reading is 90.0 mi/h, what is the smallest finite speed that it could register?

Both the pressure and the electric signal are measured simultaneously for various settings, and the results are tabulated. For the given set of measurements, obtain the calibration curve in the form of P = aI + b, where a and b are constants, and calculate the pressure that corresponds to a signal of 10 mA.
Express the equations 1 and 2 in Cartesian coordinate LA 2 cose sine 4 (1) LAk E, = -jen sin6, (2) where A (A=na?) is the coil area, k= 2nd (where A is the wavelength at the operating frequency in free space) is the wave number, 7 = rolE, is the wave impedance in free space, j = /-T is the imaginary unit, and the indices m=1 and m=2 denote the incident and reflected fields, respectively. Note that the magnetic and electric fields that are expressed in equations (1) and (2) do not strictly represent the evanescent fields because they do not decrease exponentially with increasing distance. They are actually localized slowly-evanescent fields“ and we refer
