3. SIL, intensity, and fallOH: Someone 10 In away from you is speaking quietly. such that you hear a sound intensity level (SlL) of 3 dBp. (a) Intensity and power: \"(hat is the intensity in \"Ting? How much power total would enter your ear hole if it is 5 mm diameter? Is this result bananas? (b) Fall-off: \"'hat intensity would you observe at a distance of 100 111'? How many decibels quieter is this? What is the SIL at this distance? Beyond what distance will you not be able to hear anything (assuming your sensitivity is 1 pW'Q'm2) (e) Optional practice: Suppose you have an ideal ear horn (or a parabolic dish) that collects sound from a larger area and focuses it on your ear hole. \"'11:\": diameter liornl,"disl1 would you need in order to this signal at 100 m
