Chapter 29, Problem 6TYK
Summary Introduction
To analyze: The mechanism of volume and sound pitch determination by the brain.
Introduction: Sensory receptors enable humans to experience the environment. The ears make humans to enable for hearing; cochlea is a small bone found in the inner ear that has receptors for the stimulus against the environmental pressure. Sound vibration generates the pressure on cochlea that provides stimuli for the volume and pitch determination of sound.

In general, humans can hear sounds between _____ Hz and _____ Hz, and they are most sensitive to sound between _____ Hz and _____ Hz. A _____ dB sound is perceived as twice as loud as a 20 dB sound. A _____ dB sound has an amplitude ten times greater than a 20 dB sound. A ______ periodic tone is made up of many ______ periodic tones called harmonics.arrow_forward
- What evidence suggests that absolute pitch depends on special experiences?arrow_forwardRegarding auditory physiology, what is the mechanism that generates an action potential and release of neurotransmitter substance? a) pressure waves on cells in the vestibular membrane b) movement of the membrane covering the round window c) movement of the hair cells of the coil member towards the tectorial membrane d) movement of cells in the basement membrane towards the cochleaarrow_forwardThrough which mechanism do we perceive low-frequency sounds (up to about 100 Hz)?arrow_forward
- How does the brain recognize the difference betweenthe musical notes high C and middle C? Between a loudsound and a soft one?arrow_forwardHow do we localize where sound is coming from and which structures are responsible? Select all that apply: a. The auditory nerve communicates with the vestibular nuclei to process information about the body's location b. Medial geniculate nucleus processes visual stimuli to locate visual cues associated with the sound c. The hair cells simultaneously process information about frequency as well as the location the sound originated in d. Lateral superior olives respond to differences in the amplitude of sound waves from each ear e. Medial superior olives respond to differences in the time it takes sound to arrive in each eararrow_forwardThe gustatory cortex is in the: a) temporal lobe and interpretes auditory patterns. b) parietal lobes and is important for the sense of taste. c) frontal lobe and helps control muscles of speech. d) occipital lobe and recognizes visual patterns.arrow_forward
