Table 2
Sound field parameters used in the evaluation, sorted by category. Full names are given for parameters whose short names may be ambiguous. For full definitions, see Bergner and Peissig [31] and Bergner et al. [12]. Parameters are marked according to the pressure (p), Ambisonics (A) or binaural (B) stimulus representations they depend upon. Underlined parameters are computed from broadband signals and in four frequency bands.
