Resonances of the ear canal lead to increased sensitivity of hearing, as we've seen. Dogs have a much longer ear canal\(5.2 \mathrm{~cm}\)-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 \(350 \mathrm{~m} / \mathrm{s}\).

A. \(1700 \mathrm{~Hz}, 3400 \mathrm{~Hz}\)

B. \(1700 \mathrm{~Hz}, 5100 \mathrm{~Hz}\)

C. \(3400 \mathrm{~Hz}, 6800 \mathrm{~Hz}\)

D. \(3400 \mathrm{~Hz}, 10,200 \mathrm{~Hz}\)
