| This lesson is part of the Fundamentals of Sound & Music module. |
Objectives
- Student will understand the relationship between perceived loudness and amplitude
- Student will understand how pitch and amplitude interact to create perceived loudness
- Students will understand how amplitude relates to the aural concept of volume and in turn, notated dynamics
- Student will understand the scale derivation of decibels
- Student will be able to visualize amplitude and loudness on oscilloscopes and spectrograms
- Student will be able to notate various dynamic levels
