Document Summary
Binaural cues: both ears, itd (interaural time difference) for low frequencies the leading edge of the wave always reaches the closer ear first, ild (interaural level difference) Head = a sound shadow = acoustic. Spl (sound pressure level) = decibel (db) Level = sound pressure level = intensity for high frequency (> 1,000hz: cone of confusion. Same ild (interaural level difference) & itd (interaural time. Substantial reduction of the intensity: determination by the elevation of the sound, ild & itd are not effective for elevation, spectral cues are created by the. Hrtf (head related transfer function: as sounds bounce around , their spectra are, hrtf has characteristic notches for specific frequencies at modified. Auditory space: because the proximal stimuli overlap, sounds at different locations create an auditory space. Auditory localization: locating of sound sources in auditory space. Distance information: loudness / sound pressure, reflection / reverberation, frequency. Sounds that are further away tend to have more indirect components.
