Transcript

  • 1.  Making Sound Waves: A sound wave begins with a vibration. How Sound Travels: Like other mechanical waves, sound waves carry energy through a medium without moving the particles of the medium along.
  • 2.  Reflection: Sound waves may reflect whenthey hit a surface Diffraction: Have you sound waves can alsodiffract, bend around corners,this is why you can hear someonetalking around the corner beforegoing around the corner. Interference: Sound waves may meet and interactwith each other.
  • 3.  Elasticity: If you stretch a rubber bandand then let it go, it returns to its original shape,however when you stretch modeling clay it staystretched elasticity is the ability of materialbouncing back after being disturbed. Density: Density is how much matter,or mass there is in a given amount of space, orvolume Temperature: In a given medium,sound travels more slowly at a lower temperature.At a low temperature the particles of a medium moremove slowly then at a high temperature.
  • 4.  Energy of a Sound Wave: in general the greater the energy used to make the sound the louder the sound. Distance From a Sound Source: loudness increases the closer you are to the sound source. Measuring Loudness: The loudness of different sounds is compared using a unit call the decibels (dB).
  • 5.  Pitch and Frequency: Sounds with a high frequency have a high pitch,sounds with a low frequency have a low pitch. Changing Pitch: Pitch is an important property off music becausemusic usually uses specific pitches called notes.
  • 6.  What Causes The Doppler Effect: When a sound source moves the frequencyof the waves changes because the motionof the source adds to the motion of the waves. What Causes Shock waves: When the plane travels almost as fast as thespeed of sound the sound barrier is broken
  • 7.  Fundamental tones and overtones: You may recall that standing waves occur whenwaves with just the right frequency interfere as theyreflect back and forth. Resonance: Resonance affects the soundquality of a musical instrument by increasing the loudnessof certain overtones.
  • 8.  Stringed Instruments: The guitar and violin are stringedinstruments. Wind Instruments: Wing instruments include brass instrumentsSuch as trumpets and woodwind instruments suchas clarinets. Percussion Instruments: Percussion instruments include drums bellscymbals and xylophones.
  • 9.  Acoustics is used in the design of correct halls to reverberation and interference.
  • 10.  Outer Ear: The outer part of you ear actsas a funnel and collects sound. Middle Ear: Behind the ear drum isthe middle ear, the middle ear contain 3 ofthe smallest bones in you body called thehammer, the anvil, and stirrup. Inner Ear: A membrane separates themiddle ear form the inner ear the thirdsection of the ear.
  • 11.  Causes of Hearing Loss: hearing loss can occur suddenly if the eardrumis damaged or punctured Hearing Aid: For some types of hearing lossthe hearing aids can restore some ability to hear.
  • 12.  Bats: Bats can use ultrasound waves withfrequencies up to 100,000 Hz to movearound and hunt. Dolphins, Porpoises, Whales: Dolphins, porpoises, and whales something haveto hunt in the darkness so like the bats they useecholocation ultrasounds up to 150,00 Hz
  • 13.  Sonar: A system that uses reflected sounds waveto detect and locate objectsunderwater is called sonar. Ultrasound Imagine: Doctors use ultrasound imaging to look inside the human body.
  • 14.  Microphone: The microphone converts acoustic sound energy into electrical energy. Some hearing aids use two microphones to help separate background noise. Processor: The processor digitizes the acoustic sound, then separates background noise from speech. Both are processed to make speech clearer and to reduce the interference of background noise. Amplifier: The amplifier boosts the processed signal according to the pattern and severity of your hearing loss, as well as the amount of background noise. Speaker: The speaker converts the electrical signal back into acoustic sound and directs the sound into your ear canal. Some models have the speaker placed in your ear canal. Some use a tube that connects the speaker to plug or custom ear mold. Others have the components housed in a custom-fitting shell. Battery compartment: The battery powers the electronic components. The battery compartment is used to turn the hearing aid on and off. Optional controls: Some models have a volume control to regulate the volume. Others have a program control, enabling you to change the processing for different listening situations, such as high background noise or music. These controls are available on the hearing aids or on a remote control.
  • 15.  Sound quality is a blend tones.
  • 16.  Ultrasound is used to look inside human bodies like if a woman if pregnant you can see the baby inside and all(:
