Discussion:
The sound sensor uses an internal microphone and special amplifier. Sound waves
enter through the hole in the top of the sensor's plastic body so you should point
that directly towards the sound source for best readings.
The sound sensor has two modes (ranges) of operation:
1. Arbitrary analog units (Arb) – An arbitrary unit indicates a number
according to signal shape. At this mode, the sound is sampled and
reconstructed as a signal.
2. Decibel (dB) – A unit of measure to show the intensity (loudness of sound).
Please note that this is a logarithmic unit.
At this mode, the wave is sampled and the average intensity (calculated by
the sensor controller) is converted into dB value. 40 dB represents silence.
In this experiment, we shall use it at dB mode and we assume its ID is 1 as the
default ID.
Selecting the range should be done by the NeuLog software.
