The Sound of Poetry

Slide 2

Basic Sound Principles

Resonance – designates the ability of a vibration to reach out through waves to set off a similar vibration in another body

Physics – sound vibrations are connected to the vibrations of atoms and molecules in the air

Life is composed of atoms which contain protons and electrons. These are electrically charged particles of energy, in constant motion

Slide 3

Transmission of a resonant vibration

requires three things:

Must be an original vibrating energy source. Can be thought, sounds, colours, musical instruments, voices

Must be a transmitting medium – air is most common carrier

There must be a receiver of the vibration, something which will receive and respond to the energy or sound vibration being sent

Slide 4

The Effects of Sound

in any form – are cumulative and detectable.

Sound in any of its forms is a source of energy

Effective as a tool to alter the electromagnetic fields and impulses of a human or an environment

Slide 5

Pitch of Sound

Pitch is the highness or lowness of the sound

Pitch is determined by the speed at which it vibrates. The faster the sound vibrates, the higher the pitch

Low tones bend around objects when they are emitted

High-pitched tones are more focused

Slide 6

Decibel Levels

one decibel is the quietest sound the average person can hear

decibels increase their effects logarithically

10 decibels of sound is ten times greater than one decibel

Slide 7

Decibel Levels

20 decibels is 10 times greater than the ten decibel range or 100 times greater than 1 decibel

90 decibels – the range we can hear now – is equal to the sound of one train pulling into a subway station

100 decibels is equal to the sound of 10 trains pulling into the subway station at the same time

Slide 8

Wave Patterns of Sound

Waves - Rhythic disturbance that carries energy

Wavelength - Distance between a point on a wave and the identical point on the next wave.

Period - Time required for one wavelength to pass

Frequency - Number of waves passing per second. The unit of measure is hertz (Hz).
