Audio basics: The characteristics of sound

“

how it travels, and what some of its characteristics are. We'll learn about compression and rarefaction to understand how sound waves behave, on the audio events we hear. When a physical event occurs in nature, it causes vibrations that we perceive as sound. The vibration of the object causes changes in the surrounding air pressure. As air molecules are displaced, in some areas, and low pressure in others. As the vibration continues, a repeating pattern of compressions and rarefactions occurs The sound wave moves through the acoustic space, eventually reaching our ears, where we perceive it as a sound. as the amplitude of the measurement. This affects our perception of the loudness of the sound. We measure amplitude or loudness in decibels, or dB. of compressions and rarefactions occurs per second, we can determine the frequency of the sound wave. The frequency affects our perception of the pitch of the sound. by measuring the sound wave is what we commonly refer to as a waveform.…
