- How is intensity defined?
- Why do we use logarithimic numbers and decibels?
- What is the benefit of a logarithimic scale?
- How do you use a sound level meter in the clinic?
- How is loudness judged?
- a by the human listener
cannot be measured by equipment
- b because values in watts are too cumbersome
- c 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
- d it is capable of accomodating a large range of numbers in a very straight forward and visually intuitive way
- e 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)
5 Multiple Choice Questions
- *how much energy is radiated
*it is measured in watts
*represents the amount of energy transfer in a given amount of time
- *overall capacity of a person's voice
*the shape and dimensions of VRP will vary across individuals and within individuals before and after treatment
- Our hearing is not equally sensitive to all frequencies; it is heavily influenced by the frequency that we are listening to
- 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
- making a connection between somebody's perceptual response or experience to a physical measure that links the two parameters together
5 True/False Questions
What does RMS represent? → the amplitude of the signal
What does a transducer do? → 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
At which range do our ears have substantially less sensitivity to sound? → very low frequencies and very high frequencies
What is a VRP and what does it do? → Voice Range Profile: measures dynamic range; from lowest to highest intensity across a person's (dB range) Fo range
What type of characteristic is loudness and what does it correlate to? → Voice Range Profile: measures dynamic range; from lowest to highest intensity across a person's (dB range) Fo range
