The auditory canal of the ear is filled with air. One end is open, and the other one is closed by the eardrum. A particular person's auditory canal is 2.2 cm long and can be modeled as a pipe. What is the fundamental frequency of this person's auditory canal? The speed of sound in air is 343 m/s.
For a winged instrument, an antinode is formed on the open end and a node on the closed end. This implies that the longest wavelength is when L = ¼λ.
- Length L = 2.2 cm = 2.2/100 m
