ISO 532-1:2017 electronic attachment — validation data#

What this folder contains#

Reference test signals and validation data from the electronic attachment of ISO 532-1:2017 (Acoustics — Methods for calculating loudness — Part 1: Zwicker method), used by this library's test suite and conformance report to validate the loudness_zwicker implementation against the standard's own Annex B programme, exactly as Annex B specifies.

File(s) Origin in the attachment Content
Annex B.5/Test signal 14 … 25 *.wav Annex B.5/ (unchanged names) The twelve recorded technical signals for time-varying loudness validation
iso532_1_test_signal_10.wav … 13.wav Annex B.4/Test signal 10 (tone pulse 1 kHz 10 ms 70 dB).wav … 13 (combined tone pulses 1 kHz).wav Tone-pulse synthetic signals (renamed; content byte-identical)
iso532_1_test_signal_1_levels.txt Annex B.2/Test signal 1.txt Third-octave levels of test signal 1 (renamed; content byte-identical)
iso532_1_annexB_expected.json transcribed from the Results and tests … workbooks (Annexes B.2–B.5) Expected loudness values and tolerances used as test oracles
iso532_1_annexB4_traces.npz transcribed from Annex B.4/Results and tests for synthetic signals (time varying loudness).xlsx Reference loudness-vs-time traces for signals 10–13

All .wav and .txt files are byte-identical to the files in the official attachment archive (verified by checksum at the time of import). The .json and .npz files are transcriptions of numeric values from the attachment's result workbooks, not original ISO files.

Source and authorship#

Purpose and scope of use#

ISO publishes this attachment so that implementations of the ISO 532-1 method can be validated against the standard's reference signals and tolerances (Annex B). The copies in this folder serve exactly that purpose: they are consumed by tests/test_loudness.py and scripts/conformance_report.py to demonstrate conformance of this library's independent implementation. They are not part of the phonometry package, are not installed with it, and are not covered by this repository's MIT licence — ISO's terms apply to them.

The remainder of the attachment (the reference C programme, executables and result workbooks) is intentionally not included: this library's implementation is written independently from the text of the standard.

Removal policy#

If you represent ISO and consider that this redistribution exceeds the intended use of the electronic attachment, please open an issue or contact the maintainer (see CITATION.cff) and the files will be removed promptly. The test suite degrades gracefully: without this folder the affected tests skip (set ISO532_1_TESTDATA to a local copy of the attachment to restore them).
