The drawing shows a loudspeaker A and point C, where a listeer is positioned. A second loudspeaker B is located somewhere to the right of A. Both speakers vibrate in phase and are playing a 58.9-Hz tone. The speed of sound is 340 m/s. What is the closest to speaker A that speaker B can be located, so that the listener hears no sound?
Homework Answers
For listener to hear no sound, there should be destructive
interference at point C between the sound waves from the two
speakers.
That means that the 2 sound waves must be 180° out of phase at
point C.
If speakers A and B are as close as possible, The distance from B
to C must be half a wavelength more than the distance from A to
C.
To find the wavelength, we use the relationship:
wave speed = frequency * wavelength
