The lowest frequency an average human ear can perceive is about 15 Hz, and the highest about 18 kHz. How tall would an organ pipe have to be to produce the lowest note? How short a tube would be needed to play the highest note? What harmonic (i.e., what value of n in Eq. 13.15) would the smaller tube excite in the larger one?

(reference equation 13.15)
