Quizplus · Accepted Answer

When two sound waves of slightly different frequencies are played together, they create a fluctuation in their combined amplitude, known as beats. The frequency of the beats is equal to the difference between the two original frequencies, in this case, 350 Hz - 340 Hz = 10 Hz. Therefore, the listener would hear the guitar string as a single tone with the periodic variation of intensity or volume caused by the beats.
