T length of an adult human ear canal is 2.5 cm. What is the fundamental resonant freq inside it is at body temperature (37°C). he typical uency of the ear canal? Assume the air Enter answer here Scroll to Back

What effect would you expect this to have on their sensitivity to different frequencies? Select the correct answer O They should be more sensitive to lower frequencies because of resonance in the ear canal The different length of ear canal should have no effect on frequency perception because only the resonant wavelength and not the frequency will change. oos O They should be more sensitive to higher frequencies because of resonance in the ear canal The different length of ear canal should have na effect on frequency perception because the speed of sound is the same regardless. 0 of 3 attempts used CHECK ANSWER 0ntion Scroll
