Applications/Examples of results
■Purpose The CI value* is a value that takes into account the time-averaged sound level and sharpness. It is simple and effective for applications involving environmental noise and machine noise (such as dental drills). (The scope of application will be further examined in the future.) The M7SLM-8X11N-LA819AF sound quality evaluation function is designed for steady sounds. For non-steady sound loudness, please use the sound quality evaluation software from the Oscope series.
