  3. What does assembling a psycho physical scale mean?
  4. How do you use a sound level meter in the clinic?
  5. What type of characteristic is loudness and what does it correlate to?
  1. a 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)
  2. b making a connection between somebody's perceptual response or experience to a physical measure that links the two parameters together
  3. c the signal goes up and down in it's amplitude all the time so it is constantly changing.

  5. e a perceptual characteristic

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. *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. Fo increases tend to be associated with amplitude increases due to physiological reasons
  4. relative measures as long as you're comparing like with like
  5. the middle range around 1000 Hz

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 happens when we adjust the loudness of our speech?the intensity drops not in proportion to the distance but in proportion to the square of the distance


  3. 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.


  4. What is a VRP and what does it do?measures intensity in decibels


  5. 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
