  1. 1. Chapter 11 How Is Sound Produced, Propagated and Perceived?
  2. 2. We humans communicate with each other through sounds. It enables us to send across a massage to someone, be it a comment, a joke or a cry for help. It aids us in letting out our Emotions and a facilities an effective transfer of information, making it a channel for our enjoyment and enhancement. But what is exactly is a sound?
  3. 3. SOUND PRODUCTION , PROPAGATION AND PERCEPTION <ul><li>Sound Waves </li></ul><ul><li>Production Sound </li></ul><ul><li>Propagation of Sound </li></ul><ul><li>Perception of Sound </li></ul><ul><li>Picth </li></ul>
  4. 4. SOUND WAVES <ul><li>Sound waves carry energy, as do all waves. This means that the source of the sound must supply energy. </li></ul><ul><li>Playing an instrument for an extended period of time is also very tiring. </li></ul><ul><li>Sound waves are longitudinal. </li></ul>
  5. 5. PRODUCTION OF SOUND <ul><li>Sound is produced when a vibration causes pressure variation in a medium. </li></ul><ul><li>The human voice uses several types of sound production and modification mechanics. </li></ul>
  6. 6. PROPAGATION OF SOUND <ul><li>A Medium is a material to travel through. </li></ul><ul><li>Sound waves can travel though solids, liquids, and gases but mot through a vacuum. </li></ul><ul><li>Reflection and diffraction have large effects on the sound you hear. </li></ul>
  7. 7. PERCEPTION OF SOUND
  8. 8. <ul><li>The ear is an amazing sound detector. </li></ul><ul><li>- it can detect sound waves </li></ul><ul><li>- sensitive to an enormous range of wave amplitude </li></ul><ul><li>- a complex sense organ </li></ul>
  9. 9. <ul><li>HOW TO DETECT A SOUND? </li></ul><ul><li>Pitch </li></ul><ul><li>Loudness </li></ul><ul><li>Tone Quality </li></ul>
  10. 10. PITCH <ul><li>the PITCH of a sound is the perception of highness and lowness of a sound. </li></ul><ul><li>Sound frequency is the number of sound waves that passes through a point in a certain amount of time. </li></ul><ul><li>The Hertz (Hz) is a unit to measure frequency a so pitch is measured in hertz this is called the audio frequency range. </li></ul>
  11. 11. LOUDNESS <ul><li>Loudness of a sound is determined mainly by the amplitude of the sound wave. </li></ul><ul><li>Intensity is a defined by a physical quantity that defends on the amplitude of a sound. </li></ul><ul><li>Cause pain and damaged to the ear is called threshold of pain . </li></ul>
  12. 12. TIMBRE <ul><li>The timbre of a sound is used to distinguish between two different sounds that have the same pitch and loudness. </li></ul><ul><li>Pure tone is a simplest wave form have a soft ,pleasant tone quality and sinosoidal. </li></ul>
