The commercially available microdensitometers are not well suited to making such studies unless proper means are taken to assure correct comparisons with data obtained with a calibrated reproducer. The present paper describes the modifications of a Moll microdensitometer that have converted it into a satisfactory instrument for sound-picture investigations.", "abstract$meta": { "confidence": "high", "note": "Parsed from NLM article XML (_source/SMPTE/HIGHWIRE/Source Bak/smptej/10.5594_J08750.xml)", "source": "parsed", "updated": "2026-05-22T19:19:44.900Z", "version": "smpte-journal-article-nlm@v1" }, "articleType": "research-article", "articleType$meta": { "confidence": "high", "note": "Parsed from NLM article XML (_source/SMPTE/HIGHWIRE/Source Bak/smptej/10.5594_J08750.xml)", "source": "parsed", "updated": "2026-05-22T19:19:44.900Z", "version": "smpte-journal-article-nlm@v1" }, "authors": [ "W.
