Resonances of the ear canal lead to increased sensitivity of hearing, as we've seen. Dogs have a much longer ear canal-5.2 cm-than humans. What are the two lowest frequencies at which dogs have an increase in sensitivity? The speed of sound in the warm air of the ear is 350 m/s. A 1700 Hz, 3400 Hz B. 1700Hz, 5100Hz C. 3400 Hz, 6800 Hz D. 3400 Hz, 1 0,200 Hz
