In Brüel & Kjær's Evolution Of Hearing Simulation - Part 1 video, well-known acoustic specialist Mr. John Bareham explained the development of hearing simulation from back in the 1970’s up to 2019, and why we use ear simulators. You can watch it below:
Next week, Brüel & Kjær will be releasing Evolution Of Hearing Simulation - Part 2, in which their new measurement standard -- the Brüel & Kjær 5128 -- is explained. Based on research by Brüel & Kjær from 2003 to 2017, the 5128 provides the most human-like ear simulator to date, an important evolution beyond the simplistic geometry of current ear simulators.
We've been measuring with the 5128 since late last year here at Head-Fi HQ, and will be shifting over to the 5128 as our primary measurement fixture. The results so far have been exciting, and it will provide measurements that provide greater clarity, more closely aligning with our subjective impressions of headphones (both in-ear and around-ear/on-ear).
Please watch Part 1 above, and then Part 2 next week.
EDIT 2020-03-30 0544 EDT: Part 2 is posted immediately below. In this video (below), I narrate the research and development of the new Brüel & Kjær 5128 High-Frequency HATS, focusing on what was needed to create a human-like ear canal and inner ear. The 5128 represents the new standard for measurement -- the most human-like ear simulator available.
