Sound enters the ear, travels through the auditory canal, and reaches the eardrum. the auditory canal is approximately a tube open at only one end. the other end is closed by the eardrum. a typical length for the auditory canal in an adult is about 2.26 cm. the speed of sound is 348 m/s. what is the fundamental frequency of the canal? (interestingly, the fundamental frequency is in the frequency range where human hearing is most sensitive.)
