Good Day
I am writing on behalf of a blind colleague of mine who also has a hearing issue, please assist with his request below:
“Hello FxSound Team,
I need an urgent, accessible solution to surgically suppress—not merely reduce gain—two distortion components while streaming all Windows audio via Bluetooth to my Phonak Lumity hearing aid:
- 250 Hz humming distortion (left ear only)
- Low‑frequency occlusion/muffled “mic” distortion centered around 125 Hz (left ear only)
My situation:
- Right ear: almost completely deaf. Left ear: the only functional ear.
- The humming and occlusion are triggered only when hearing or speaking; silence is quiet.
- Equalizer APO created device conflicts and only “turns down” gain—it does not surgically notch or desensitize.
- I need a simple, standalone Windows app that applies tight, high‑Q notches system‑wide and integrates cleanly with Bluetooth (no complex routing, no plugins).
- I have visual impairment, so I need step‑by‑step guidance with a clean UI and minimal steps.
What I need FxSound to do:
1. System‑wide, real‑time, high‑Q notch at 250 Hz (e.g., Q ≥ 10, deep cut), applied to all audio (YouTube, calls, music), streamed via Bluetooth.
2. Simultaneous suppression of occlusion around 125 Hz (either a second high‑Q notch centered on 125 Hz or a very steep low‑shelf cut below ~150 Hz), without degrading speech clarity above that band.
3. Target only the left channel, leaving the right channel untouched (Windows device balance: Right = 0, Left = 100).
4. Operate offline once installed (no always‑on internet requirement).
5. Keep the signal stable and clean over Bluetooth to Phonak Lumity, avoiding added artifacts or latency.
6. Provide an accessible preset I can load, labeled “Surgical Notch 250 + Occlusion 125 (Left‑only)”.
Please confirm:
- That FxSound can implement true narrow‑band notches (not just general EQ gain dips).
- How to set precise frequency, Q, and deep attenuation for 250 Hz, plus 125 Hz occlusion control.
- How to lock output to the left ear using Windows balance or in‑app routing.
- Whether FxSound runs fully offline after installation.
- The most stable workflow to pair Windows → Phonak via Bluetooth and ensure FxSound remains the active system device.
- Any recommended latency settings or “exclusive mode” flags to keep the processing smooth.
For swift communication:
- Please provide a staff or assistance email address I can use for follow‑ups on this specific case, in addition to your support portal. A direct line will help me avoid delays.
Thank you for prioritizing this. My goal is long‑term desensitization through continuous exposure to surgically notched audio, not masking, and not mere gain reduction. I appreciate your urgent help.”
