THD 97 HBK Do Physical Domain Acoustic Metrics Translate Well to Human Perception?

12 days ago

The Total Harmonic Discussion / the THD Podcast. A weekly discussion on audio and headphone technologies and the people who bring the technology to market.

In episode 97, Vince Rey of Hottinger Brüel & Kjær (HBK) joins again from California to discuss the Buzz, Squeak, and Rattle or ‘BSR’ test audio quality metric. It was developed by Dr. Wookeun Song (HBK). This BSR metric relies on deconvolution and time-varying loudness sound quality, considering frequency and time masking on the human ear. It can be summarised as 'Does the measurement curve match the perception of the sound quality and how can we correlate the two?'
