Suppose a piano tuner hears 2 beats/second when listening to the combined sound from the tuning fork and the piano note being tuned. After slightly loosening the string, she hears 1 beat/second. Should she continue to loosen the string or tighten it in order to get it “in tune”? Defend your answer with 3 – 4 complete sentences.

You hear the difference frequency. You want it to be zero. So loosen it more :)

LOL..... no you want the frquency to be zero yes! but you don't lossen it you have to tighten it

Oh sry I didn't read the question right yes Damon is right yo will loosen it

To determine whether the piano tuner should continue to loosen or tighten the string, we need to understand the relationship between beats and tuning. Beats occur when two sounds have slightly different frequencies. In this scenario, the tuner initially hears 2 beats/second, which indicates that the piano string is slightly sharp. By loosening the string, the frequency decreases, resulting in a reduced beating rate of 1 beat/second. Therefore, the tuner should continue to loosen the string until no beats are heard, indicating that the piano note is in tune.
