is a sound wave with wave length 1.32 cm and wave velocity 330 m/s audible to a human ear? Why?

Let us find the frequency ν = V/λ, V is velocity of sound and λ is wavelength .
ν = 330 / (1.32×10-2) = 25000 Hz .
since audiable range of sound is 20 Hz to 20 kHz, this sound is not audiable. The frequency range is Ultrasonic sound frequency
