My psychophysics as a bilateral cochlear implant user

What HN thinks

A Korean CI user runs 10,992 trials on themselves and HN, against all odds, mostly responds with kindness and DSP homework.

Admiration and encouragement for the author
Many found the self-experimentation moving and hacker-spirited, dismissed AI-slop accusations, and urged the author to keep publishing.
Try signal-processing experiments
Commenters suggested pitch-shifting, slowing, low-pass filtering or band-slicing music, and possibly EEG, to probe what the implant actually conveys; a debate clarified that the 70 Hz limit is a modulation rate, not an audio frequency.
The company and clinicians should be helping
Several were troubled that the trial sponsor offered no support and that the author must rely on AI alone, recommending a clinician or DSP expert examine the hardware and mapping.

Consensus: Most agree the write-up is valuable and that the author deserves real expert help with device mapping, which the implant company has failed to provide.

Recommended in the comments

Audacity (tool): Suggested for slowing or pitch-shifting music into the frequency range the author perceives best.
GitHub Pages (service): Recommended to publish the findings in a better-organised, navigable form.
Online Tone Generator ↗ (service): Shared so hearing readers can get a feel for the 10-70 Hz range discussed.
