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 SoundSensorDataInterval has elapsed.

If a SoundSensorSPLChangeTrigger has been set to a non-zero value, the SoundSensor_SPLChange event will not occur until the SoundSensordB SPL value has changed by at least the SoundSensorSPLChangeTrigger value.
The dB SPL value is calculated from the SoundSensorOctaves data.
The dBA SPL value is calculated by applying a A-weighted filter to the SoundSensorOctaves data.
The dBC SPL value is calculated by applying a C-weighted filter to the SoundSensorOctaves 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
