PA Designer Learn 3: Data Analysis

3. Running Data Analysis

      1. Select the Main Code cell
      2. Click on Run Selected Cell

This re-initializes all the variables and collects 10 seconds of loudness data.

      1. Select the Data Analysis cell
      2. Click on Run Selected Cell again.

You should see two graphs like the ones displayed below. Each dot in these graphs is a point in time measurement of loudness. In the engineering world, we call these measurements sample points.

Most of the sample points in our example graphs have loudness values that lie within a horizontal band. This is the ambient noise of your environment. For a noise to be identifiable above ambient noise, it must generate loudness values higher than this.
