Audio BasicsWhat are the important attributes of sound? Loudness (loudness) Loudness is the size of the various sounds that humans can perceive, that is, the volume. Loudness is directly related to the amplitude of sound waves. Tone (Pitch) The tone is related to the frequency of the sound, and the greater the frequency of the sound, the higher the tone the human ear perceives, or the lower it will become. Tone (Qu
