  • Front
  • Back
The visual field is the seeing as the ______ is to hearing.
Soundscape.
Size of pressure change.
Amplitude
The number of times per second that the pressure changes repeat.
Frequency
The psychological quality of a tone that we describe as "high" or "low."
Pitch
Pattern of air pressure changes, traveling through the air at 340 meters per second.
Sound Wave
Uninformative, incidental sound in the environment.
Noise
Pressure changes occuring in a pattern described by the function sine wave.
Pure Tone
Larger amplitudes are associated with this increased perceptual experience.
Loudness
Unit of sound. A physical measure related to a psychological experience.
Decibel
The measurement of frequency.
Hertz
The range of hearing.
20 Hz to 20,000 Hz.
Indicates sensitivity to sound changes across the range of hearing.
Audibility Curve.
The psychophysically measured area that defines the frequencies and sound pressure levels over which hearing functions.
Auditory Response Area
This indicates the number of decibels that create the same perception of loudness at different frequencies.
Equal Loudness Curve
Used to produce complex sounds by adding simple components.
Additive Synthesis
A plot that indicates the amplitude of the various harmonics that make up a complex tone.
Frequency Spectrum
The buildup of sound at the beginning of the tone.
Attack
The decrease in sound at the end of the tone.
Decay
Repeating pattern of pressure changes.
Periodic Sounds
Sound waves that do not repeat.
Aperiodic Sounds
The frequency at which something vibrates when it's struck.
Resonant Frequency
Occurs when sound waves are reflected back from teh closed end of the auditory canal interact with sound waves that are entering the auditory canal.
Resonance
The frequency of a sound is indicated by the place along the Organ of Corti at which nerve firing is highest.
Place Theorgy of Hearing
An orderly map of frequencies along the length of the cochlea.
Tonotopic Map
Cells are tuned to specific frequencies (characteristic frequencies). This is preserved throughout the auditory system.
Tonotopic Organization
The curve related frequency and the threshold intensity for activating an auditory neuron, measured in dB.
Frequency Tuning Curve
The frequency to which the neuron is most sensitive.
Characteristic Frequency
One tone can mask or decrease our perception of another tone that is occurring at the same time.
Auditory Masking
A response to sound of the outer hair cells in which these cells move.
Motile Response
This indicates the intensity of masking tones of different frequencies that cause a low-intensity pure tone to become just barely detectable.
Psychophysical Tuning Curve
Breaking down a complex tone into a number of sine-wave component. Working backwards.
Fourier Analysis
The firing of auditory neurons in synchrony with the phase of an auditory stimulus.
Phase Locking
