The mysterious Dr. H. does not like surprise guests. He has created a fear emitter, based on sub-sonics, to install atop the keep building at the center of his ancestral compound. His (secret and not IRE-approved) studies at the local laundromat show that the average aversion felt by humans to the fear sound occurs at an intensity of 20 dB and his source will produce 2000 +/- 2% dB. 8. Is this problem exploring the equivalent of a charge, field, flux, or potential (circle one)? Why do you say this? b. A group of three kids approaching the Horrible Compound turned around 1832 m, 1667 m and 1533 m, respectively. Estimate the sonic permittivity of the atmosphere for this infrasonic system. C.ln order that Dr. H. does not lose hench-folk, he must mount a sonic dampener. Without damping, what would be the intensity of the feeling on an average human being at the front gate, 100 m away from emitter
