chapter 11: hearing Flashcards
vision
Light photons bouncing off objects and hitting our eyes. Retinal receptors then convert photon
energy to neural energy (transduction)
audition
Air pressure changes in the environment are received by outer and middle ear structures. They
pass it onto receptors in the inner ear. These receptors convert mechanical energy (hair cells literally
being pushed by ‘conducted’ sound waves) to neural energy (transduction)
periodic waveform
repeating pattern with constant wavelength and frequency
fundamental frequency
repetition rate
harmonics
multiple of the fundamental frequency of a periodic signal
webers law of just noticeable difference
minimum amount of change in a physical stimulus required to detect a difference between one sensory experience and another
difference threshold
increases as stimulus becomes more intense
what is the human range of hearing ?
20 hz- 20,000 hz
tone height
moving higher in frequency
tone chroma
notes with the same letter sound similar
timbre
the unique quality or “color” of a sound, distinguishing between instruments or voices
resonance
reinforcing or prolonging a frequency, due to the
reverberation within the auditory canal
resonant frequency of the ear canal
1,000 and 5,000 Hz
first ossicle in the middle ear
malleus
second ossicle in the middle ear
incus
last ossicle in the middle ear
stapes
