cochlea of ear perceive and respond to various frequencies in sound...
Approx. 80 Hz
Different animals can perceive sounds at different wavelengths. For example a dog whistle has a frequency which dogs can hear but is too high for humans. Furthermore, people's sensitivity to sound frequency changes with age. In general, ordinary range for humans is 20 to 20,000 Hz.

Frequency
Humans can hear sounds of 20 to 20,000 Hz. Hearing is best in the middle part of this range. However, the acuity varies between individuals and changes with age so that there is no specific frequency at which humans hear best.
With your ears. The faster the vibration, the higher the frequency. A low frequency vibration will be felt more than heard.
We perceive the loudness of a sound wave as a consequence of its amplitude. The frequency of a sound wave determines the pitch we perceive.
Energy changes the frequency of things. Specifically, the higher the energy, the higher the frequency.
FM signals travel as changes in the frequency of the wave.ANSWER: DEFINITELY not frequency remains the same.The duty cycle changes.It definitely IS the the frequency which changes. It changes at the same rate as the frequency of the modulation.It can be demodulated with a frequency discriminator. If the frequency remained constant and its "duty cycle" changed, the discriminator wouldn't demodulate it.
