Anechoic chamber: Type of room with almost totally sound-absorbing walls, frequently used for experimentation under free-field-like conditions.Auditory object: Perception corresponding to a single sound source.Attributes of auditory objects are location and extent.Auditory spatial image: Illusion of perception of a space with auditory objects of specific extent and at specific locations.BCC: Coding of stereo or multi-channel signals using a down-mix and binaural cues (or spatial parameters) to describe inter-channel relationships. Binaural cues: Inter-channel cues between the left and right ear entrance signals (see also ITD, ILD, and IC).BMLD: Binaural masking level difference.The difference in masked threshold due to different spatial cues of masker and target signal.BRIR: Binaural room impulse response, modeling transduction of sound from a source to left and right ear entrances in enclosed spaces.The difference from HTRFs is that BRIRs also consider reflections.
