The theory of sound and hearing Task 1
Introduction to what sound is, How we perceive sound, how it coralates to the recording industry and what I intend to analyse and How.
How sound works Analyse amplitude, frequency and quality
harmonic content or timbre
explain velocity and the speed of sound
Explain phase, acoustic envelope and wave length
EXplain the harmonic content of a sawtooth triangle and square waves including a description of the amplitude relationship between frequencies
Provide examples of the first 10 harmonics for each waveform based on the fundamental frequency of 32 hz
Explain how velocity amplitude and frequency are related
calculating the speed of sound
velocity eq frequency and amplitide equation use a smart way of presenting
Describe how a sawtooth triangle and square wave help us to understand the difference between strinn instruments and tubalar intstruments in terms of sounds that are produced. Use picture diagrams
Discuss the importance of non harmonic partials in the differiation of timbre
How this relates to the harmonic series to a variation of instruments - use photos and diagrams
Explain how velocity of sound is dependent on the medium that it travels in - use example and a diagram and what is meant by elastic properties
use relevant example of how sound travels through air solid and water
explaining factors that will efffect this such as the differenece between longitudinal waves and transverse waves
Explain what is compression and rarefraction
Explain what is meant by waveguide
excitation source and resonator - examples
use relevant examples to show how elements vary between instruments to create a variety of ways to generate sound and non musical sound
Explain the importance of envelope
vibrato
tremolo
in terms of instrumental timbre
