Output-specific qualifications#
Benchmark results remain tied to the version and configuration tested. Later changes to atmospheric attenuation, decay fitting and qualification require relevant evidence to be repeated. Encouraging benchmark results do not establish performance in every room or for every output.
Interpreting numerical qualifications#
Numerical support concerns whether the calculation has sufficient numerical evidence for a requested output. Response completeness concerns whether omitted or unresolved energy can materially affect that output. Physical applicability concerns whether the geometry and acoustic model represent the intended room. These are separate questions.
An estimate must retain its specific limitation. An unavailable quantity is not zero. Sampling stability addresses one part of uncertainty; it does not account for every uncertainty in geometry, materials, sources or the physical model.
Physical and output limitations#
- Statistical reverberation relies on diffuse-field assumptions and does not predict listener-dependent reflections.
- Geometrical ray analysis does not model low-frequency modes, coherent interference, diffraction, transmission or flanking paths.
- Incomplete receiver responses can affect decay, clarity, centre time and levels differently.
- Decay comparison evidence does not automatically validate clarity, sound levels, speech or audio rendering.
- Generic material/source inputs and interpolated maps add assumptions, not independent measured evidence.
- Listening previews are illustrative; they do not reproduce calibrated SPL or guarantee the finished room's sound.
