(Answered) 1 assume that the outer ear canal is a cylincrical pipe 3

Academics

1. Assume that the outer ear canal is a cylincrical pipe 3 cm long, closed at one end by the eardum. Calculate the resonant frequency (fundamental, v1) of this pipe. Our hearing should be especially sensitive for frequencies near this resonance.

2. A "tonic" chord in the musical key of A-major consists of tones with frequencies of 440, 550, and 660 Hz (A, C# and E). When such a chord is played on the piano or by three instruments, why is this not heard as a single tone with a pitch of 110 Hz (the "missing fundamental")?
