A resonant frequency is a frequency that resonates within a tube of some length. The first resonant frequency of the average ear canal is around 3,000 Hz. Look at the Fletcher-Munson diagram. Which of the following statements is correct?

The intensity level of the first resonant frequency is the only thing that matters.

The first resonant frequency fits well within a frequency range where the ear is maximally sensitive.

The first resonant frequency corresponds poorly to the frequency range where the ear is maximally sensitive.

There is no meaningful relationship between the first resonant frequency and the Fletcher-Munson diagram.

Isn't the ear more sensitive to3000hz than any other freq? Have you looked at the diagram? http://www.system1audio.com/images/fletchermunson.gif

Yeah, I am having trouble interpreting it. I think The first resonant frequency fits well within a frequency range where the ear is maximally sensitive makes the most sense

The lowest point is the most sensitive to the ear: that is the 0 dbm point.

The larger the frequency of the tuning fork, the smaller the length of the tube at which you hear the resonant sound. Explain why this is so (think in terms of the relationship between frequency and wavelength).
