For characterizing product sound quality this software is designed to quantifying acoustic emissions in terms of how humans respond to them, by recording data for post-processing
Sound Quality Metrics Software - 8405-G
This BK Connect® option analyses product sound quality using parameters that closely relate to the complete human experience of the sound, rather than using purely physical quantities such as sound pressure. The software can analyze recorded measurements using sound quality metrics such as ‘loudness’. Users can filter the sound using these sound quality parameters, to deliver engineering targets and understand the value of potential changes.
Conventional, physical sound analysis deals with sound in the air. Sound quality metrics measure the effects our ears have on the sound before it reaches our brains, such as favouring certain frequencies. Sound quality metrics also measure how our mental processes determine how the sound affects us. Some metrics such as Zwicker Loudness attempt to understand how the human ear experiences sounds by properly weighting the different parts of the sound signal. Other metrics like articulation index quantify factors such as how easy it is to hold a conversation near the sound source. By using combinations of such objective sound quality metrics to describe the outcomes of these complex psychoacoustic phenomena, you can reliably quantify them in a repeatable way that gives clear engineering directions.
You can view analysis results in terms of sound quality metrics such as ‘roughness’ or ‘sharpness’, alongside the conventional units such as sound pressure level. At the same time, the sounds can be played back, while viewing their spectral content in a spectrogram display. The user can also select just the valid sections of the time history.
