Loudness as a Perception of Sound Wave Amplitude
The perceived loudness of a sound is directly related to the amplitude of its sound wave. Waves with higher amplitudes are interpreted as louder sounds, while those with lower amplitudes are perceived as quieter. This perceptual quality is measured using a logarithmic unit of sound intensity called decibels (dB).

Encoding pitch information
An audio engineer is editing a recording of a flute. They determine that the sound needs to be perceived as both higher in pitch and louder. Which of the following adjustments to the sound wave's physical properties would accomplish this?
An audio engineer is comparing two distinct sound waves. Sound Wave 1 has a high frequency and a low amplitude. Sound Wave 2 has a low frequency and a high amplitude. How would a listener most likely perceive the difference between the sound produced by Wave 1 and the sound produced by Wave 2?
