Our reading of the claim

Reference (stated reasonable reading)

Late

Criterion: Small personal audio devices create a convincing spatial auditory environment.

Deadline: 2010 · Included in this comparison

At original deadlinePARTLY FULFILLED
By review dateFULFILLED

Audio spatialization and directed-sound hardware existed by 2010, but the tiny ordinary personal implementation was incomplete. Small AirPods with dynamic head-tracked spatial audio are documented by 2021. This meets the perceptual function, not the ultrasonic projection mechanism emphasized in the explanatory discussion.

Deadline and follow-up notes

At deadline: Audio spatialization and directed-sound hardware existed by 2010, but the tiny ordinary personal implementation was incomplete.

By review: Small AirPods with dynamic head-tracked spatial audio are documented by 2021. This meets the perceptual function, not the ultrasonic projection mechanism emphasized in the explanatory discussion.

Capability, adoption, and timing

A related breakthrough is not automatically fulfillment. Review must check the actual capability, how widely it was required to be used, the specified technology, and the original deadline. A prototype cannot establish a claim about routine or widespread use.

Alternative interpretation: Functional audio success is not a claim of ultrasound projection. 2021 is a documented-by date; no exact first commercial year is asserted.

Research notes & history

Functional audio success is not a claim of ultrasound projection. 2021 is a documented-by date; no exact first commercial year is asserted.

Open questions

  • Original-edition collation remains an attribution task; it does not erase the stated outcome assessment.
  • An earlier documented instance could refine timing; the documented-by date is not claimed to be the invention year.

Review history

— Evidence v0.2: UNREVIEWED. The earlier LRAD/bone-conduction examples were not evidence of the complete claimed device. Attribution is located but performance, form factor and deadline still need resolution. Change: Complete deadline/current outcome assessment under explicit scope; separate uncertainty from verdict.

— Evidence v0.3: EDITORIAL_ASSESSMENT_COMPLETE; supplied verdict LATE. Audio spatialization and directed-sound hardware existed by 2010, but the tiny ordinary personal implementation was incomplete. Small AirPods with dynamic head-tracked spatial audio are documented by 2021. This meets the perceptual function, not the ultrasonic projection mechanism emphasized in the explanatory discussion.
