Talking Points

Recent interactions between the hosts and their guests.

THD Podcast 133 - Absolute Audio Labs Creates Software for Hearing Aids and Earbuds, Enhancing Sound Clarity
Q: How much work can the battery company partners contribute to complement what you're doing?
The collaboration is more about roadmap alignment and exchange of information rather than direct technical integration, with battery partners helping optimize power budgets and inform design choices for longer battery life.
THD Podcast 137 - THD 137 Triad Semiconductor 156dB Range Current-Conveyor AFE Handles Mic & +28dBu Ln Signals w/o Pads
Q: What does the DC servo do in this design?
It looks at DC offset after the front end and injects a tiny correction to the middle current node, so gain changes don't produce audible clicks or transient artifacts.
THD Podcast 137 - THD 137 Triad Semiconductor 156dB Range Current-Conveyor AFE Handles Mic & +28dBu Ln Signals w/o Pads
Q: Tony, what this instrument amplifier, why wouldn't you just put your differential signal straight on to A3 plus and minus?
The first stage provides input impedance control and noise performance; removing it would leave the system with a higher and less controllable impedance, making it harder to manage noise and common-mode rejection before hitting the ADC.
THD Podcast 136 - Hearing Health and Auracast: The Mission to Overcome the 10% Global Market Penetration
Q: How close are consumer earbuds to delivering hearing-assist performance, and what are the hardware trade-offs?
Consumer earbuds can deliver situational amplification with simpler processing and lower power consumption, using mass-market chips and software like AI noise suppression, but they face challenges in bass, battery life for all-day wear, and avoiding feedback if speakers are not properly vented.
THD Podcast 136 - Hearing Health and Auracast: The Mission to Overcome the 10% Global Market Penetration
Q: What practical differences did deregulation create between the old FDA rules and the new OTC framework?
Under the old rules, devices had to be approved as hearing aids and fit by audiologists to be called hearing aids, but OTC loosened these constraints and allowed self-fitting devices to serve mild-to-moderate hearing loss, expanding access though with certain output limits.
