ECHOSTRATA / INDUSTRIAL INTELLIGENCE
The operating loop

Four steps. Context all the way through.

01

Capture

Collect acoustic signals from a suitable sensor or existing industrial audio source.

→
02

Understand

Characterize the signal and compare equivalent operating states with relevant baselines.

→
03

Surface

Highlight unusual events with spectral, timing, trend, and confidence context.

→
04

Act

Review the evidence, decide what needs inspection, and record the outcome.

Conceptual architecture. The capture path and deployment design depend on your use case.

Before the first alert

A useful baseline starts with real operating conditions.

The sound of a machine changes with the work it does. A good comparison accounts for that variation.

  1. Map the asset

    Identify equipment type, operating modes, the process, and available maintenance history.

  2. Check signal quality

    Review clipping, silence, environmental noise, sensor placement, and recording consistency.

  3. Build a representative reference

    Include relevant loads, speeds, and operating cycles before interpreting unusual patterns.

  4. Agree the review workflow

    Define who examines events, what evidence they need, and how findings are recorded.

After an event

The finding belongs with the evidence.

An anomaly is a lead for investigation. The review should distinguish what the signal shows from what remains a hypothesis.

  • Review the original sound and spectral evidence.
  • Compare operating state and supporting telemetry.
  • Decide whether physical inspection is warranted.
  • Record technician findings and the follow-up readings.
  • Assess false alerts and model drift over time.
