Week 5 Acoustic & Perceptual Eval

Front

Acoustic analysis

Back

Non-invasive objective data collection that can measure changes in voice over time by obtaining a baseline at evaluation and monitoring changes during and after therapy

Front

Factors that influence results of analysis

Back

Instructions

Environmental influence (Including watching the analysis on the screen)

Recording procedures

Front

Intensity

Back

Acoustic correlate of volume or loudness

Front

Fundamental frequency (F0)

Back

Acoustic correlate of pitch; the lowest frequency component we see on an acoustic exam (e.g., spectrogram)

Front

Spectrogram

Back

A visual representation of voice analysis that shows variations in amplitude (loudness) and frequency (pitch) over time

Front

Total Phonational Frequency (F0) Range

Back

Range between the lowest pitch and frequency in modal register (chest voice) to the highest pitch and frequency in falsetto (head voice)

Front

Perturbation

Back

Correlate of dysphonia in which vocal quality is disrupted

Front

Jitter

Back

Cycle-to-cycle variations in frequency; measure of short-term instability

Front

Shimmer

Back

Cycle-to-cycle variations in amplitude; measure of short-term instability

Front

Harmonic

Back

A multiple of fundamental frequency that are evenly spaced
