5 Matching questions

  1. What can RMS be applied to?
  2. What does a sound level meter do?
  3. How do you use a sound level meter in the clinic?
  4. What is the benefit of a logarithimic scale?
  5. Ideas to keep in mind when using VRP in practice are:
  1. a measures intensity in decibels
  2. b periodic sounds
    number of harmonic components
    aperiodic sounds
  3. c 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)
  4. d *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. e it is capable of accomodating a large range of numbers in a very straight forward and visually intuitive way

5 Multiple choice questions

  1. *how much energy is radiated
    *it is measured in watts
    *represents the amount of energy transfer in a given amount of time
  2. the signal goes up and down in it's amplitude all the time so it is constantly changing.
  3. *distance is crucial: it must be known or at least kept constant from one session to another because of the inverse square law
    *keep mouth to mic distance constant
    *keep input settings constant for each session
  4. a perceptual characteristic
  5. Fo increases tend to be associated with amplitude increases due to physiological reasons

5 True/False questions

  1. What is the general principle of the inverse square law?to specify exactly how the intensity of sound diminishes as the hearer/recorder gets further away form the speaker/sound source


  2. Data collected from the VRP can tell us what?*overall capacity of a person's voice
    *the shape and dimensions of VRP will vary across individuals and within individuals before and after treatment


  3. How is loudness judged?by the human listener
    cannot be measured by equipment


  4. Explain why the articulators would move more for louder speech.the pressure within the oral cavity is much higher so you would need more forceful closure of the lips for a bilabial stop because if you increased the pressure and didn't increase the lip closure force, you would end up leaking air when you really wanted to have good stop closure


  5. What does assembling a psycho physical scale mean?describes how sound diminishes as the distance from the sound source increases
