Loudness & Dynamics: Difference between revisions

Revision as of 23:01, 16 July 2020

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
