Pitch and Loudness: Investigating Sound Waves on an Oscilloscope

The video tutorial explores how sound waves are represented on an oscilloscope. It explains the relationship between the amplitude of the oscilloscope trace and the loudness of the sound, as well as the relationship between the frequency of the trace and the pitch of the sound. The tutorial covers the oscilloscope's Y and X axes, detailing how voltage and time are represented. It further discusses how larger amplitudes indicate louder sounds and higher frequencies correspond to higher pitch sounds.
