- What happens when we adjust the loudness of our speech?
- What does a sound level meter do?
- The inverse square law has important implications for what?
- Loudness is influenced by what?
- Decibels are a logarithmic measure of what?
- a *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
- b 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
- c frequency and spectrum
- d intensity
- e measures intensity in decibels
5 Multiple Choice Questions
- Our hearing is not equally sensitive to all frequencies; it is heavily influenced by the frequency that we are listening to
- *overall capacity of a person's voice
*the shape and dimensions of VRP will vary across individuals and within individuals before and after treatment
- to specify exactly how the intensity of sound diminishes as the hearer/recorder gets further away form the speaker/sound source
- the amplitude of the signal
- very low frequencies and very high frequencies
5 True/False Questions
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
Why do we use logarithimic numbers and decibels? → because values in watts are too cumbersome
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.
What is acoustic power? → *how much energy is radiated
*it is measured in watts
*represents the amount of energy transfer in a given amount of time
What happens as the radius gets bigger? → the intensity drops not in proportion to the distance but in proportion to the square of the distance
