Problem 1: Birds on tree One bird can sing with the sound intensity level of 5 dB measured by the listener near the tree. Suppose there are many birds on the tree which all sing in phase with the same amplitude and frequency. The same listener measures the sound intensity level 25 dB at the same position as before. How many birds arc there on the trec? (i) 10 (ii) 25 iv) 50 v) 100

While at a party, you pull up a sound intensity level app on your phone (everyone does stuff like that, right?), and it reads 89 dB . You look around and count 34 people talking. If you assume that each person contributes the same amount of noise, determine the sound intensity level of one of those people talking.
