Please answer both questions carefully
(a) Determine the intensity of sound in W/m2 reaching a person sitting at a distance of 5 m from a 200-W loud speaker. (b) The level of sound for threshold of hearing with intensity given by 1,-10x 10 given by 1,- 1.0x 10-12 W/m Wm is 0 decibel. Find the intensity of sound for a level of 50 decibels hi threshold of hearing.

Using a frequency-measuring lab device, I am to map out the sound intensity level distribution (dB) in a room (both with & without music playing) to create a 5x5 grid of 25 data points. Using the following data table of sound intensity level β(dB) and corresponding intensity I(W/m2), I also need to find the intensity to the nearest order of magnitude for the points on my sound intensity level maps. Here is the data table: Intensity levelβ(dB) Intensity I(W/m2) Example/effect...
