PSYC 212 Chapter Notes - Chapter 6: Interaural Time Difference, The Cocktail Party, Missing Fundamental
Document Summary
In this chapter, you will learn about hearing, which is the perceptual experience that results from the processing of auditory signals. To begin, you will learn about the absolute threshold for detection of an auditory stimulus and difference thresholds, as well as the procedures used to determine these thresholds. The sone scale of loudness will be explained and the intensity loudness relationship will be discussed. You will learn the 10 decibel rule, which states that the perception of loudness is doubled with a 10 decibel increase in sound intensity. The perception of frequency and pitch is discussed next. Humans can detect sound frequencies in the range of 20 to 20,000 hz. Frequencies below this range are called infrasonic and those above are ultrasonic. Acoustic pitch is discussed and you will learn that there is not an exact relationship between pitch and frequency.
