Problem 4: A crude approximation of human voice production is to consider the breathing passages and mouth to be a resonating tube closed at one end. (See the figure) 2 Nasal cavity Soft palate- TongueS EpiglottisS PharynxS -Vocal cord Larynx Trachea Part (a) What is the fundamental frequency, in hertz, of a voice if the tube is 0.18-m long, taking air temperature to be 37.0°C? Numeric : A numeric value is expected and not an expression. fi = Part (b) What would this frequency become, in hertz, if the person replaced the air with helium? Assume the same temperature dependence for the speed of sound in helium as for air, and that the speed of sound in Helium is 965 m/s at 0°C. Numeric : A numeric value is expected and not an expression. f2 =
