Move the filtering out of the electronics

→ production · part of the filtering done without electronics

The problem

Acoustic filtering to achieve on an auscultation device.

The classic approach would have processed the signal electronically, downstream — a better algorithm, more compute.

The governing constraint

The real need wasn't a better algorithm.

What was needed was to physically separate the useful frequency components of the signal, as close to the source as possible — not to recover them afterwards through computation.

The approach

Find the principle in another field.

Look at how the human cochlea works — it naturally sorts frequencies. Design a biomimetic acoustic and mechanical architecture that does part of the filtering without electronics, ahead of any digital processing.

The result

→ production
a working architecture, then industrialised and produced
0 compute
part of the filtering handled by mechanics, before the digital stage
