5 Matching questions

  1. What can RMS be applied to?
  2. What is the inverse square law?
  3. How do you use a sound level meter in the clinic?
  4. There are some things to keep in mind when using a sound meter level. They are:
  5. What is acoustic power?
  1. a *how much energy is radiated
    *it is measured in watts
    *represents the amount of energy transfer in a given amount of time
  2. b describes how sound diminishes as the distance from the sound source increases
  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 *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
  5. e periodic sounds
    number of harmonic components
    aperiodic sounds

5 Multiple choice questions

  1. measures intensity in decibels
  2. *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
  3. the middle range around 1000 Hz
  4. the amplitude of the signal
  5. Our hearing is not equally sensitive to all frequencies; it is heavily influenced by the frequency that we are listening to

5 True/False questions

  1. When doing research and publishing it is important to state these 2 things.measuring sound pressure level in decibels of a person's spoken output because the distance of our measuring device from the speaker makes an enormous difference to the actual decibel values that we measure

          

  2. 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

          

  3. At which range do our ears have substantially less sensitivity to sound?the middle range around 1000 Hz

          

  4. Ideas to keep in mind when using VRP in practice are:it allows us to span a wide range of intensitites using numbers that aren't absolutely enormous or totally minuscule.

          

  5. In the clinic what measurments are ok to use?relative measures as long as you're comparing like with like
