PLACID PSE Sound express

Sound express software
Sound level meter module

Overview

PLACID SoundExpress is software developed by PLACID Instruments for testing acoustic indicators. It has functions for sound power, material test, sound pressure level, and sound intensity. The functions of the sound level meter module are described in detail in this datasheet.

Function

SOUND LEVEL METER TEST INTERFACE

The measured data includes:
✓RMS value: It is the linear average of all measured values at a sampling point
✓Sound pressure value: The value of the sound pressure level, calculated using time weighting,showing how much it has changed over time.
✓Maximum value: The maximum SPL value in the overall measurement time
✓Minimum value: The minimum SPL value in the overall measurement time
✓Peak value: The time-domain signal’s highest possible positive value over the course of the entire measurement time
✓Equivalent continuity: by integrating the RMS value, the equivalent continuous sound pressure level in the entire measurement time
✓Sound exposure: The level of sound exposure over the course of the entire measurement, as determined by integrating the RMS value
✓L10: The noise level that exceeds 10% of the total measurement time is equivalent to the noise’s average peak.
✓L50: The noise level that exceeds 50% of the total measurement time is equivalent to the noise’s average peak.
✓L90: The noise level that exceeds 90% of the total measurement time is equivalent to the noise’s average peak.
