Broadband acoustical parameters estimates (means across all frequency bands) for measured (ID 1) and best-case modeled (ID 4) BRIRs. Differences (and % changes) are also shown, as are estimates of the JND for each acoustical parameter determined from previous studies.
| Measured (ID 1) | Modeled (ID 4) | Difference | JND | ||||
|---|---|---|---|---|---|---|---|
| Broadband Parameter | T60 (ms) | 445.8 | 432.3 | 13.5 | (3%) | 24 ms | (Seraphim, 1958) |
| C50 (dB) | 10.6 | 6.8 | 3.8 | (36%) | 1.1 dB | (Bradley et al., 1999) | |
| Tc (ms) | 21.8 | 24.9 | −3.1 | (−14%) | 5.7–11.4 ms | (Cox et al., 1993) | |
| IACC | 0.718 | 0.659 | 0.1 | (8%) | 5% | (Okano, 2002) | |
| fc (Hz) | 1557 | 1525 | 32 | (2%) | 7% | (Emiroglu and Kollmeier, 2008) | |
