What sets our sound testing lab apart:

  • ISO 17025 accredited facility with dedicated quiet room
  • Binaural (Aachen) head for realistic human hearing simulation
  • Multi-channel simultaneous sound and vibration data acquisition
  • Portable system for on-site and in-vehicle measurements
  • Expertise with Ford SSQT and major OEM sound quality protocols

Types of Sound Testing & Analysis We Perform

Our sound testing lab offers a comprehensive range of acoustic measurement and analysis services.

Sound Quality Evaluation

Sound quality testing goes beyond simple decibel measurements to evaluate how a product sounds to human ears. We quantify subjective acoustic qualities that influence customer perception:

  • Zwicker Loudness analysis (ISO 532)
  • Sharpness, roughness, and fluctuation strength metrics
  • Jury evaluation correlation
  • Competitive benchmarking studies

Component Actuation Sound Testing

We evaluate the sounds produced by automotive and consumer product mechanisms during operation. Our expertise includes:

  • Window regulators, latches, and liftgates
  • Pedals and parking brake actuation noise (PF-12460)
  • Seat adjusters and mechanisms
  • Switches and electromechanical components

Binaural Head Measurements

Our binaural (Aachen) head captures sound exactly as a human listener would hear it, enabling realistic spatial audio analysis. This technique is essential for:

  • In-vehicle cabin noise assessment
  • Product sound signature characterization
  • Spatial sound source localization
  • Playback and jury evaluation studies

Environmental Noise Assessment

We perform room and environmental noise assessments to established standards:

  • ANSI/ASA S12.2 room noise evaluation
  • Background noise characterization
  • Noise criteria (NC) rating determination
  • 1/nth octave and FFT spectral analysis

Frequently Asked Questions

What is sound testing?

Sound testing is the measurement and analysis of acoustic emissions from products, components, or environments. It quantifies characteristics like loudness, frequency content, and sound quality to help manufacturers optimize product acoustics for customer satisfaction and regulatory compliance.

What is a sound testing lab?

A sound testing lab is a specialized facility with acoustically controlled environments, precision microphones, and analysis software to perform accurate, repeatable sound measurements. Testrium’s quiet room achieves background noise below 24 dBA, ensuring test results are not contaminated by ambient noise.

What is sound quality testing?

Sound quality testing goes beyond measuring volume to evaluate how a product sounds to the human ear. Metrics like Zwicker Loudness, sharpness, and roughness quantify subjective perception, helping engineers design products that sound premium and satisfying.

What is a binaural head?

A binaural (Aachen) head is a measurement device shaped like a human head with microphones positioned at the ear canals. It captures sound exactly as a person would hear it, including spatial and directional information, enabling realistic playback and analysis.

Can you perform on-site sound testing?

Yes. Our portable multi-channel data acquisition system allows us to perform sound measurements at your facility or in-vehicle, in addition to testing in our quiet room.

What is the Ford SSQT?

The Ford Simple Sound Quality Tool (SSQT) is Ford Motor Company’s standardized method for evaluating component sound quality. Testrium has specific expertise with SSQT testing protocols for window regulators, latches, pedals, and other mechanisms.
