## Phidget Sound Sensor.lvlib:SoundSensorEventExe.vi

The most recent SPL values the channel has measured will be reported in this event, which occurs when the `DataInterval` has elapsed.

- If a `SPLChangeTrigger` has been set to a non-zero value, the `SPLChange` event will not occur until the `dB` SPL value has changed by at least the `SPLChangeTrigger` value.
- The dB SPL value is calculated from the `Octaves` data.
- The dBA SPL value is calculated by applying a A-weighted filter to the `Octaves` data.
- The dBC SPL value is calculated by applying a C-weighted filter to the `Octaves` data.
- The following frequency bands are represented:

- octaves[0] = 31.5 Hz
- octaves[1] = 63 Hz
- octaves[2] = 125 Hz
- octaves[3] = 250 Hz
- octaves[4] = 500 Hz
- octaves[5] = 1 kHz
- octaves[6] = 2 kHz
- octaves[7] = 4 kHz
- octaves[8] = 8 kHz
- octaves[9] = 16 kHz
