By quantifying sound properties and considering factors that influence accuracy, sound measurements allow for effective noise control, assessment of environmental noise, protection of human hearing, and advancement in scientific research and engineering applications.
I understand that amplitude determines volume and frequency determines pitch. What changes the quality of a sound? For example, an oboe, a violin, and the speaker in this video can all produce a sustained 440 hz A at the same volume. Why do they sound different?
When you show sound waves on a graph, the amplitude is the height of the waves from their middle position and reflects how loud the waves are. Loudness of sound is measured in decibels (dB). This is actually a measure of intensity, which relates to how much energy the pressure wave has.
A sound wave is displayed as though it were a transverse wave on the screen of the oscilloscope. The time base can be used to measure a full time period of the wave cycle. The height of the wave (measured from the centre of the screen) is related to the amplitude of the sound.

Want to understand the science behind audio waveforms? This guide explores six essential techniques for measuring and analyzing sound, perfect for audio enthusiasts and beginners.
Sound intensity measurement is a powerful technique that allows us to measure the flow of sound energy as a time-averaged vector quantity. The properties of sound intensity allow us to separate sound sources and to distinguish direct sound from reverberant sound in a room.
