Tuning a piano wire: When we hear two frequencies which are very close to each other but not exactly equal then distinct waxing and waning of the intensity of the sound is heard. These are known as beats. The beat frequency is equal to the absolute value of the difference in frequency of the two waves. To tune a piano, a musician takes help of beat frequency. He plucks the string and tap a tuning fork at the same time. If the two sound sources— the piano string and the tuning fork, do not produce identical frequency then the musician hears detectable beats. Musician will then adjust the tension of the piano string and repeat the process until the beats are no longer be heard. Tension of the wire changes the frequency of the wire.
As the piano string becomes more in tune with the tuning fork, the beat frequency reduces and approaches 0 Hz. When beats are no longer heard, the piano string is tuned to the tuning fork; i.e. they play the same frequency. The process allows the musician to match the strings' frequencies to the frequencies of a standardized set of tuning forks.
Q. A musician while tuning a piano with a standard tuning fork of frequency 256 Hz, hears beats of 5 Hz. What may be the frequency of the piano?
  • a)
    261 Hz or 251 Hz
  • b)
    Beat frequency has no relation with the piano frequency
  • c)
    251 Hz
  • d)
    261 Hz
Correct answer is option 'A'. Can you explain this answer?

The beat frequency is equal to the absolute value of the difference in frequency of the two waves. So, piano wire frequency is (256 + 5) Hz or (256 – 5)Hz
