Acoustic & Noise Testing

Overview

Sound Power & Pressure Testing for Noise Compliance

Our acoustic and noise testing services provide rigorous measurement and analysis to ensure your product meets the noise emission requirements of its target deployment environment — from data centers and enterprise IT to industrial and commercial settings.

We conduct operator and bystander noise assessments in accordance with international standards, measuring both sound power level (LWA) and sound pressure level (LpA) across defined positions and distances. Hemisphere scanning methods capture full spatial noise distribution, delivering accurate characterization of how and where acoustic energy radiates from your product.

Compliance-Driven Noise Validation

Whether your product must meet OSHA occupational noise limits, ISO 7779 / ECMA-74 IT equipment standards, or customer-specified deployment thresholds, our team designs test protocols tailored to your certification requirements. Results include detailed octave-band analysis, tonal component identification, and actionable engineering data to support noise reduction and design optimization.

From individual components to full rack-level systems, we help manufacturers bring compliant, market-ready products to market faster.
