It is not the speed that matters, but the frequency. Human ears can hear frequencies between about 20 and 20,000 Hz (vibrations per second). In older people, this range becomes less.
The faster the wave speed, the higher the pitch of the sound will be. 20 vibrations is the lowest amount of vibrations needed per second for a human to be able to hear it
With a speed of 331 m/s and a frequency of 20 Hz the wavelength is (331 m/s)/(20 Hz)=16,55 m .
When a sound wave is reflected, you hear an echo.
No, the pilot does not hear the pressure wave that causes the boom when he is going faster than the speed of sound.
I would call it "the speed of the wave".

Speed is not a wave.
Infrasonic waves are waves which are below humans hearing range while ultrasonic waves are waves which human beings can hear. Example-bat,dog etc and human beings (respectively)

you can hear by sound wave and ears
... wave's speed of propagation.
Both the wavelength and the frequency of a wave affect the speed of a wave.
The wavelength of a wave is calculated using the formula: Wavelength = speed of the wave divided by the frequency of the wave. For radio waves and other wireless signals as well as the speed a signal travels along a wire, the speed of the wave is approximately 299,792,458 meters per second (the speed of light).
wave speed
wave speed= frequency/wavelenth
