What are the four features of the scientific method? - ANSWER-empirical deterministic predictive parsimonious What does empirical mean? - ANSWER-based on data What does deterministic mean? - ANSWER-obey physical laws What does predictive mean? - ANSWER-show what will happen What does parsimonious mean? - ANSWER-use the simplest explanation possible Why do SLPs use technology in clinical practices? - ANSWER-to overcome listener bias to describe severity objectively to demonstrate treatment efficacy (track progress) to provide biofeedback What is the difference between pitch perception and frequency measurement? - ANSWER-pitch is subjective to the listener frequency is objective and can be measured How do waveforms differ as frequency goes up or down? - ANSWER-higher frequency wavelengths appear closer together with more frequency over a period of time than lower frequencies What is the difference between loudness perception and intensity measurement? - ANSWER-Loudness is subjective and cannot be measured Intensity is objective and can be measured by equipment What are the units of measurement for intensity? - ANSWER-HL SPL What is difference limens? - ANSWER-the smallest detectable change (DL) What is the difference limens for frequency? - ANSWER-DLs become larger as the frequency decreases What is the difference limens for intensity? - ANSWER-DLs become larger as the intensity decreases How does a complex periodic sound change when the fundamental is removed or muted? - ANSWER-when removed, the timbre (quality) differs, but the pitch is perceived as the same How many semitones are in one octave? - ANSWER-12 What is a voice range profile (VPR)? - ANSWER-a visual representation of a person's the amplitude and fundamental frequency range How is the VRP computed and what does it show? - ANSWER-x-axis represents the fundamental frequency range y-axis represents the amplitude What is the root mean square amplitude? - ANSWER-refers to the square root of the mean of the squares of the value What is the inverse square law? - ANSWER-it states that intensity is inversely proportional to the square of the distance from the source
