Relation Between Amplitude and Frequency - VEDANTU
The frequency units are called hertz (Hz). Sounds between 20 Hz and 20,000 Hz can be heard by those with normal hearing. Ultrasound is defined as frequencies greater than 20,000 Hz. Effect of frequency and amplitude on sound A short-wavelength produces a high frequency with a higher pitch and quicker cycles.

اقرأ أكثرWhat Is the Difference Between Amplitude and Frequency?
The difference between frequency and amplitude is that frequency is a measurement of cycles per second, and amplitude is a measurement of how large a wave is. Amplitude represents the wave's energy. Waves are defined as energy transferred from one place to another. The way in which the energy travels is called the medium.

Here is the one that works best for me: The amplitude of the Fourier Transform is a metric of spectral density.
