SLPS's use of technology - - ...
- Duration and loudness - below 500 milliseconds, duration affects
perception (especially for durations 15-150 milliseconds), longer = more
audible, ear integrates the energy
Difference limens for frequency - ✔✔- Frequency difference limens (DL) --
smallest detectable change in frequency, DLs increase with stimulus
frequency,
- higher frequency sounds must differ more to be heard as different in pitch
- as intensity decreases, DLs become larger
Voice range profile - ✔✔- voice range profile (VRP) -- measures dB range
across f0 range
- Measuring vocal range: reduced loudness in some voice disorders, range
of loudness changes with pitch
- VRP data collection: 10 points between min and max f0 (linear scale - Hz
increments, log scale - in semitones) // min and max intensity at each pitch
// plot data on a chart // can calculate area // also examine shape
RMS amplitude - ✔✔- RMS = root mean square
