A sound wave's frequency is a measure of how many cycles of vibration occur per unit of time. In this case, if the frequency of a sound wave is 70 Hz, it means that the sound wave completes 70 cycles (or vibrations) per second. Higher frequencies correspond to higher-pitched sounds, while lower frequencies correspond to lower-pitched sounds.
