5 Written Questions

1. the middle range around 1000 Hz
2. to specify exactly how the intensity of sound diminishes as the hearer/recorder gets further away form the speaker/sound source
3. 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
4. periodic sounds
   number of harmonic components
   aperiodic sounds
5. 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 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

   True        False

2. How does RMS work? → root mean square

   True        False

3. How is intensity defined? → 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

   True        False

4. What does RMS represent? → 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

   True        False

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

   True        False
