Sound Power Measurements

Our unique automated scanning system delivers high-precision sound power and intensity data without requiring a lab environment. Near-field acoustic holography translates measurements into intuitive heat maps, helping clients identify dominant noise sources, validate performace specifications, and improve product design. This service supports compliance reporting, detailed modeling and noise control, and innovative solutions for quieter, more efficient systems.

Automated Sound Intensity Measurement

Acentech’s innovative robotic scanning system performs sound power and surface intensity measurements in accordance with ISO 9614-2. Combining motion control, machine vision, and probe tracking, our system captures high-resolution acoustic data in real-world settings—no lab required. The data supports regulatory reporting (e.g., AHRI 370) and advanced modeling for noise mitigation and product development.

The system has been designed to measure equipment like:

• Chillers and heat pumps
• Air handling systems
• BESS and inverters
• Fuel cells and electrical generators
• Laboratory equipment
• Server and rack equipment
• Manufacturing equipment

Sound Intensity and Holographic Visualization

Using near-field acoustic holography, Acentech helps clients visualize sound emissions in the form of intuitive heat maps. This approach translates complex data into practical insights, helping engineers identify dominant noise sources and designers reduce environmental impact while improving user comfort.
