TP25-19 Sound Directivity Index and Influenece on Sound Power CalculationCTI ATC 128 test code2019 edition, carried forward to 2024 versionchanged sound emission surfaces along with the associated sound power equation. Studies have examined the critical influence of Directivity Index (Di) and impact on sound power calculations. Correction factors may be necessary when testing for sound power of Heat Rejection Equipment (HRE) with negative Di values, where the primary sound contribution is from one or more sides as opposed
