Sam and Ryan stand at some distances apart in a park, each making sound with an identical 512Hz tuning fork. A bird resting at the midpoint between them detects a sound of intensity level of 40dB, assume this bird has a threshold of hearing of 10-14 w/m2, (I) what is the pressure amplitude of the sound wave from each tuning fork? (II) If the power output of each tuning fork is 10-6 W, how far apart are Sam and Ryan ? (III) The bird is now flying away. When the bird is 1 km from Sam, the intensity drops to 10 dB, how far is the bird from Ryan?

Two speakers are facing each other, 4.00 meters apart, in phase
and playing a sound with frequency 170HZ. Find the distance from
the center point to the nearest point where totally destructive
interference occurs.

Trademarks and trade secrets sound similar and yet
they mean something very far apart from
each other. Similarly, copyrights and patents may sound so
different and yet they may have
similarities between them” Critically analyze the above statement
augmenting your answer
with tangible examples.
Two speakers spaced a distance 1.5 m apart emit coherent sound waves at a frequency of 680 Hz in all directions. The waves start out in phase with each other.
Two speakers spaced a distance 1.5 m apart emit coherent sound waves at a frequency of 680 Hz in all directions. The waves start out in phase with each other. A listener walks in a circle of radius greater than 1 m centered on the midpoint of the two speakers. At how many points does the listener observe destructive interference? The listener and the speakers are all in the same horizontal plane and the speed of sound is 340 m/s....
