A standing wave can be created when a disturbance (wave) is trapped between two boundaries. Thus, standing sound wave can be produced when gas is confined in long narrow tube closed at both ends. In addition, standing waves can be produced in tubes with an opening at one end of the tube as well (open-closed tube). The eardrum can be modeled as an open-closed tube. The ear canal in adults is about 2.5 cm in length. Thus, what frequency ranges can occur in the ear canal that are within the range of human hearing? In other words, what is the fundamental frequency of the ear canal? The speed of sound in the warm air of the ear canal is 350 m/s. Hint: Wavelength of standing waves in open-closed tubes are given by the following: λ = 4L where m = 1,3,5,7 m
