5 Written questions

5 Matching questions

  1. What is RMS?
  2. What range do our ears have the greatest sensitivity to sounds?
  3. Why does minimum amplitude level in decibels get higher as you go left to right to the higher Fo's?
  4. What does WATTS represent?
  5. What is the general principle of the inverse square law?
  1. a the amount of energy that can be transferred by the system
    *in the case of a music system, the energy comes from a battery or from the electrical wall socket and the output from this system is acoustic energy
  2. b to specify exactly how the intensity of sound diminishes as the hearer/recorder gets further away form the speaker/sound source
  3. c root mean square
  4. d the middle range around 1000 Hz
  5. e Fo increases tend to be associated with amplitude increases due to physiological reasons

5 Multiple choice questions

  1. WATTS divided by a unit area
    *if you take the amount of energy that a stereo is giving out and divide it across the surface of a sphere you see that there's less energy availabe per unit area as that sphere gets larger
    *it is simply spread out over a larger surface
  2. as a biofeedback tool; measure clients speech intensity while they're talking and then give them feedback that will help them aim for a particular target (higher or lower depending on their need)
  3. the amplitude of the signal
  4. very low frequencies and very high frequencies
  5. *increase our subglottal pressure/more driving pressure for loud speech
    *it causes the vocal folds to move farther apart as they oscillate = more forceful vocal fold collisions
    *larger articulator movements
    *because more pressure has come from the lungs to drive the larynx, there is higher oral presure as you form consonants thus, the consonant burst release is stronger

5 True/False questions

  1. What complicates our perception of loudness?the amount of energy that can be transferred by the system
    *in the case of a music system, the energy comes from a battery or from the electrical wall socket and the output from this system is acoustic energy

          

  2. What is the benefit of a logarithimic scale?it allows us to span a wide range of intensitites using numbers that aren't absolutely enormous or totally minuscule.

          

  3. Ideas to keep in mind when using VRP in practice are:*somewhat time consuming to collect all the data points
    *useful for voice disordered patients
    *practice helps them become better
    *motivation plays a role
    *max effort can vary with instructions
    *be careful to avoid risk of vocal damage

          

  4. There are some things to keep in mind when using a sound meter level. They are:*somewhat time consuming to collect all the data points
    *useful for voice disordered patients
    *practice helps them become better
    *motivation plays a role
    *max effort can vary with instructions
    *be careful to avoid risk of vocal damage

          

  5. How is loudness judged?WATTS divided by a unit area
    *if you take the amount of energy that a stereo is giving out and divide it across the surface of a sphere you see that there's less energy availabe per unit area as that sphere gets larger
    *it is simply spread out over a larger surface
