  1. Sound Vocabulary Terms Objective (2.1):Describe the factors that affect the pitch and loudness of sound produced by vibrating objects.(2.3) Describe how sound is transmitted, reflected, and/or absorbed by different materials!!!

  2. Definition: The rapid back and forth movement of an object that causes sound. Example: Plucking a ruler on the side of a desk. (model) Example: Strumming the string on a guitar. Example: Beating a hand on a desk. Vibrations

  3. Definition: The ability to cause change. • Example: Sound waves lose energy as they travel. Therefore, sounds that travel over longer distances are more difficult to hear. 2)Energy

  4. Example: Sound waves reflect off of hard surfaces and form echoes. 3)Sound Definition: Something that can be heard-a form of energy that is transmitted by an object vibrating. Sound travels in ALL Directions.

  5. Example: Ultraviolet rays are carried to the Earth by waves of energy Waves: (definition) A disturbance that carries energy from place to place.

  6. Solids, liquids, and gasses make up the three mediums that sound travels through. Medium: The material through which a wave travels.

  7. The more energy the sound wave has the louder the sound seems. The intensity of a sound is the amount of energy it has. You hear intensity as loudness. The higher the amplitude of the sound wave, the louder the volume; the lower the amplitude of the sound wave, the softer the volume. Lot of Energy/Tall Sound Wave=Loud Volume (High Amplitude) Low Energy/Short Wave=Soft Volume (low amplitude) Volume: How loud or soft a sound is

  8. High Frequency Sound Waves High Frequency Sound Waves=5 sound waves pass a given time and point (high pitch sound) Fast Vibrations!!! Low Frequency Sound Waves=3 sound waves pass a given time and point (low pitch sound) Slow Vibrations!!! Frequency: The number of complete sound waves that pass a given point in a certain period of time.

  9. The more energy the sound wave has the louder the sound seems. The intensity of a sound is the amount of energy it has. You hear intensity as loudness. High Energy/Tall Sound Wave=Loud Sound(High Amplitude) Low Energy/Short Wave=Soft Sound (Low Amplitude) Amplitude: The amount of energy in a sound wave. (How loud or soft a sound is)

  10. High Frequency Wave High Pitch Sound Waves: These sound waves demonstrate high frequency (several sound waves in a time and space) Fast Vibrations!! Low Pitch Sound Waves: These sound waves demonstrate low frequency (only a few sound waves in a given time and space)Slow Vibrations Pitch: How high or low a sound is

  11. Wavelength: The distance between two compressions in a sound wave. Wavelength

  12. The Sound Waves bounced(reflected) off of the wall during our Bounce Lab and came back to the sound source (kids screaming) like a basketball bounces off of a wall and comes back to the passer. Echo: A sound wave that reflects off of hard and smooth surfaces.

  13. Definition: To take in another substance. • Example: Sound waves are absorbed (not reflected) by a bush and we do not hear an echo. Absorb

  14. Definition: To bounce off of another object • Example: Sound waves bounce off of hard and flat surfaces causing an echo Reflect

  15. Definition: Being able to tell the difference between different sounds. • Example: Telling the difference between the sound of a train and a plain. Sound Discrimination

  16. Strings • Brass • Woodwinds • Percussion Examples Types of Musical Instruments
