Audio system measurements - Wikipedia
Audio system measurements are used to quantify audio system performance. These measurements are made for several purposes. Designers take measurements to specify the performance of a piece of equipment. Maintenance engineers make them to ensure equipment is still working to specification, or to ensure that the cumulative defects of an audio ...
The Big Six Audio Measurements | Audio Precision | The Global …
May 17, 2022 · In audio test, there are a small number of performance benchmarks that are most important when evaluating a device-under-test (DUT). We call them “The Big Six” measurements. These are: • Level • Frequency Response • Total Harmonic Distortion plus Noise (THD+N) • Phase • Crosstalk • Signal ‑ to ‑ Noise Ratio (SNR)
