SOUND
   It is composed of waves of
 compression and rarefaction in
which the human ear is sensitive
-It simply follow an orderly pattern or
       coherence, of motion.
  -It can begin either from simple
 harmonic motions (SHMs) or from
        complicated motions.
-sound waves carry energy.

 -sound wave is a longitudinal wave.

-the size of a compression indicates how
   much energy the sound wave has.
Sound is produced
 when a vibration
  causes pressure
 variations in the
     medium.
B. HUMAN HEARING
  sound wave


vibrates ear drum



  amplified by
    bones


  converted to
nerve impulses in
    cochlea
Human voice uses
  several types of
sound production and
   modification of
    mechanisms.
The vocal chords located
  in the LARYNX (voice
    box) in the throat
 primarily produces the
sound for singing and for
      spoken vowels.
-sounds produced differ
     because of the
differences in SHAPE of
 the air cavities in the
throat, mouth and nasal
         region.
Propagation of sound

       Medium
       -Material that sound
       waves can travel
       through.
       -It can travel through
       solids, liquids and
       gases but not through a
       vacuum.
Sounds possess the
  characteristics
and properties that
  are common to all
       waves.
Just like all longitudinal
   (compression)waves, sound
    Waves possess a velocity,
     frequency, wavelength,
  phase, period, and amplitude.

  Sound waves also reflect,
refract, diffract, and interfere.
Properties of
 sound waves
II. Properties of Sound
1. PITCH
-highness or lowness of a
sound.

a. FREQUENCY
-number of sound waves
that passes through a point
in a certain amount of time,
such as one second.
-the greater the frequency,
the higher the pitch.

Hertz (Hz)- unit to measure
frequency and pitch
Audio frequency range
-Frequency ranging 20 Hz to 20 000 Hz
-Sounds that human ear can hear is an
example.
INFRASONICS
-Frequency below 20 Hz.
2. LOUDNESS or intensity
-description of how high or
   low the sound seems to a
   person
-determined mainly by the
   amplitude of the sound
   wave



a. Decibel (dB)- unit used to
measure sound intensity or
loudness.
LOUDNESS OF SOUND IN DECIBELS
Sound          Loudness (dbs) Hearing
                              Damage
Average Home   40-50

Loud Music     90-100        After long
                             exposure
Rock Concert   115-120       Progressive


Jet Engine     120-170       Pain
Threshold of
hearing
-sound of the
quietest sound
that can be
heard under
ideal conditions
is 0 dB.


Threshold of
Pain
- Sound level of
120 dB which
can pain and
damage to the
ears.
The human ear relates
    amplitude to
      loudness
         and
    frequency to
        pitch.
3. TIMBRE
-tone color or tone quality
-used to distinguished
   between two different
   sounds that have the same
   pitch and loudness
- It helps to identify what
   produced the sound
2 Different waveforms
1. Pure tone- simplest wave
    form, it has a soft,
    pleasant tone quality
    and sinusoidal
2. Complex tone- nearly
    sinusoidal
A. Speed of Sound
  Depends on:
    1. Type of medium
        -travels better through liquids and
        solids and gas
        can’t travel through a vacuum.
    2. Temperature of medium
        -travels faster at higher
        temperature.
    3. Density
         -sound moves well through dense
          materials.
    4. Elasticity
         -sound waves move fast through
          elastic materials
B. DOPPLER EFFECT

   Doppler Effect
     change in wave frequency
      caused by a moving wave
      source

moving toward you -
 pitch sounds higher
moving away from you -
 pitch sounds lower
A. Refraction of sound
-change in direction,
   as the wave moves
   from one medium to
   another
- It bends or refracts
   as they move
   through air.
Sound waves refract.
B. Reflection of sound

Echo- reflected sound
    - it is what you
   heard shortly
   after the original
C. Diffraction of Sound

- Sound waves bend or
   diffract around
   corners or barriers
   like doors and walls.
D. INTERFERENCE
the result of two or more sound
 waves overlapping
2 types

Constructive interference
-the sound waves arrive at
the same time and phase

Destructive interference
-waves arrive at interval
and are out of phase
* Fact *
     D. Resonance
      - the inducing
of vibrations of a natural
rate by a vibrating source
having the same frequency
A. Characteristics of musical sounds


           Note- basic element of music
           1. Pitch- highness or lowness of
           the note
           2. Intensity- loudness of the note
           3. Rhythm- repeating pattern of
           beats and it keeps the time to
           the music
           4. Melody- series of pitches
           5. Harmony- three or more notes
           played together.
* Fact *
Noise- unwanted sound
and a subtle pollutant
which can threaten the
Health or well being of
an individual.
CLASSIFICATION OF INSTRUMENTS


       A. Stringed instruments
       - Produce a tone when their strings
          vibrated.

       B. Wind instruments
       -contain a column of air that vibrates when
          air is blown to the instrument

       C. Percussion instruments
       -produce sound when they are struck

Physics Sounds.

  • 1.
  • 2. SOUND It is composed of waves of compression and rarefaction in which the human ear is sensitive
  • 3. -It simply follow an orderly pattern or coherence, of motion. -It can begin either from simple harmonic motions (SHMs) or from complicated motions.
  • 4. -sound waves carry energy. -sound wave is a longitudinal wave. -the size of a compression indicates how much energy the sound wave has.
  • 5. Sound is produced when a vibration causes pressure variations in the medium.
  • 6. B. HUMAN HEARING sound wave vibrates ear drum amplified by bones converted to nerve impulses in cochlea
  • 7. Human voice uses several types of sound production and modification of mechanisms.
  • 8. The vocal chords located in the LARYNX (voice box) in the throat primarily produces the sound for singing and for spoken vowels.
  • 9. -sounds produced differ because of the differences in SHAPE of the air cavities in the throat, mouth and nasal region.
  • 10. Propagation of sound Medium -Material that sound waves can travel through. -It can travel through solids, liquids and gases but not through a vacuum.
  • 11. Sounds possess the characteristics and properties that are common to all waves.
  • 12. Just like all longitudinal (compression)waves, sound Waves possess a velocity, frequency, wavelength, phase, period, and amplitude. Sound waves also reflect, refract, diffract, and interfere.
  • 15. 1. PITCH -highness or lowness of a sound. a. FREQUENCY -number of sound waves that passes through a point in a certain amount of time, such as one second. -the greater the frequency, the higher the pitch. Hertz (Hz)- unit to measure frequency and pitch
  • 16. Audio frequency range -Frequency ranging 20 Hz to 20 000 Hz -Sounds that human ear can hear is an example. INFRASONICS -Frequency below 20 Hz.
  • 17. 2. LOUDNESS or intensity -description of how high or low the sound seems to a person -determined mainly by the amplitude of the sound wave a. Decibel (dB)- unit used to measure sound intensity or loudness.
  • 18. LOUDNESS OF SOUND IN DECIBELS Sound Loudness (dbs) Hearing Damage Average Home 40-50 Loud Music 90-100 After long exposure Rock Concert 115-120 Progressive Jet Engine 120-170 Pain
  • 19. Threshold of hearing -sound of the quietest sound that can be heard under ideal conditions is 0 dB. Threshold of Pain - Sound level of 120 dB which can pain and damage to the ears.
  • 20. The human ear relates amplitude to loudness and frequency to pitch.
  • 21. 3. TIMBRE -tone color or tone quality -used to distinguished between two different sounds that have the same pitch and loudness - It helps to identify what produced the sound 2 Different waveforms 1. Pure tone- simplest wave form, it has a soft, pleasant tone quality and sinusoidal 2. Complex tone- nearly sinusoidal
  • 22. A. Speed of Sound Depends on: 1. Type of medium -travels better through liquids and solids and gas can’t travel through a vacuum. 2. Temperature of medium -travels faster at higher temperature. 3. Density -sound moves well through dense materials. 4. Elasticity -sound waves move fast through elastic materials
  • 23. B. DOPPLER EFFECT  Doppler Effect  change in wave frequency caused by a moving wave source moving toward you - pitch sounds higher moving away from you - pitch sounds lower
  • 24. A. Refraction of sound -change in direction, as the wave moves from one medium to another - It bends or refracts as they move through air.
  • 26. B. Reflection of sound Echo- reflected sound - it is what you heard shortly after the original
  • 27. C. Diffraction of Sound - Sound waves bend or diffract around corners or barriers like doors and walls.
  • 28. D. INTERFERENCE the result of two or more sound  waves overlapping
  • 29. 2 types Constructive interference -the sound waves arrive at the same time and phase Destructive interference -waves arrive at interval and are out of phase
  • 30. * Fact * D. Resonance - the inducing of vibrations of a natural rate by a vibrating source having the same frequency
  • 31. A. Characteristics of musical sounds Note- basic element of music 1. Pitch- highness or lowness of the note 2. Intensity- loudness of the note 3. Rhythm- repeating pattern of beats and it keeps the time to the music 4. Melody- series of pitches 5. Harmony- three or more notes played together.
  • 32. * Fact * Noise- unwanted sound and a subtle pollutant which can threaten the Health or well being of an individual.
  • 33. CLASSIFICATION OF INSTRUMENTS A. Stringed instruments - Produce a tone when their strings vibrated. B. Wind instruments -contain a column of air that vibrates when air is blown to the instrument C. Percussion instruments -produce sound when they are struck
