That seems odd to me. Modern digital hearing aids have a great many features that are far more costly in terms of processing power than a simple parametric EQ or minimum phase convolution. You should definitely be able to do so with less power consumption than for an analog one.
I can't see how hearing aid manufacturers are implementing Bluetooth, multiple speaker arrays with sound source detection, etc..., but can't make these fairly basic features available.
I would be be surprised if it wasn't simply misconfiguration.
- egberts1 4y agoFeatures like automatic gain control (AGC), frequency range compression (for those with a specific range loss, or amplitude compression (for those with advance dB loss) do not mean much if it doesn’t help you to discriminate bird calls. Bluetooth is just a transport carrier of whatever audio processor can do. All advance high-power digital hearing aids have failed high frequency range response time. Keyword, response time.
- sudosysgen 4y agoI understand what you are saying. I'm saying that doing this properly is a solved problem, and that power consumption isn't an issue because many of the features they do have (not AGC or frequency/amplitude compression, those are quite simple) would consume far more power than it would take to do this properly. Modern low-power DSPs can achieve latencies in the microseconds, especially for such a simple task as EQ. That's going to be far beyond human hearing to notice.
