Ralph’s ear canal is 2.79 cm long. If it is regarded as a tube that is open at one end and closed at the eardrum, what is the fundamental frequency (Hz) around which we would expect hearing to be most sensitive? Consider the anti-node of a standing wave in the ear canal to occur exactly at the end of the canal. Use 345 m/s for the speed of sound in air

    The human ear canal has a typical length of about 2.2 cm and can be modeled as a tube open at one end and closed at the eardrum. a) Calculate the fundamental frequency that humans should be expected to hear best. Assume that the speed of sound is 345 m/s in air. Looking deeply down your friends throat, or perhaps looking at a photograph, you observe the vocal tract. At the bottom of the vocal tract, when you aren't swallowing,...

    Please explain mathematically. The human ear canal is about 2.5 cm long, open to the air on the outside, but sealed by the tympanum or eardrum in the inside. Hearing is therefor especially sensitive at frequencies around 3500 Hz a) b) Explain why. At what other frequencies (20 <f< 20,000 Hz) might we expect improved hearing for the same reason? Totally trivial: The only bones in your body without an actual Latin name are the stirrups in your ears; equine...

    A tube, open at the left end and closed at the right, has standing-wave patterns at frequencies of 198 Hz and 330 Hz. The speed of sound in air is 343 m/s. The lowest two harmonics (normal modes) that these two standing waves could be are m = and The frequency of the fundamental (m = 1) is Hz. The wavelength of the fundamental mode is m. The tube is m long
