Seconds
Capture the sound with a microphone, feed its output into an oscilloscope with a calibrated timebase. Measure the time period T of the wave on the horizontal axis, then convert it into a frequency ( = 1/T)
The details depend on what type of wave you are talking about, and what exactly you want to measure about the wave.
If a radio wave has a period of one then the period wave or two would be 2. This is math.
Wave speed = (wavelength)/(period)

A wave length.
Hertz is the measure of the period so the period is 60 times a second.
The reciprocal of the period of ANY wave is the wave's frequency.
The details depend on what type of wave you are talking about, and what exactly you want to measure about the wave.
To measure the speed of a wave, you multiply the frequency by the wavelength.
If a radio wave has a period of one then the period wave or two would be 2. This is math.
Wave frequency f, and period of wave T are inverses, related by fT=1.
