Sound Power & Compliance Testing | ISO 3744 and ISO 3745

Sound power level measurement is required for CE marking, machinery noise labelling, and product certification. PLACID provides complete systems for ISO 3744 (engineering grade) and ISO 3745 (precision grade in anechoic or reverberant rooms) measurements.

• ISO 3744: Sound power determination in a free field over a reflecting plane
• ISO 3745: Sound power determination in anechoic and reverberant rooms
• Hemisphere microphone arrays for multi-point simultaneous measurement
• 16-channel simultaneous sampling for time-efficient sound power surveys
• CE marking and product certification compliance
