Product Noise
Product noise and sound emission need to be designed with both the user’s subjective experience and objective parameters in mind. Here’s how we can help.

Sound Power: Measurement and Analysis

Sound quality

Vehicle Pass-by Noise

Acoustic material testing
Noise Source Identification
By tracing noise back to very specific components, engineers can target their mitigation efforts more precisely.

Sound Intensity Mapping

Beamforming

Acoustic Holography

Spherical Beamforming

Real-Time Noise Source Identification With Acoustic Camera

Wind Tunnel Testing – Automotive

Wind Tunnel Acoustic Testing – Aerospace

Ramp Noise Testing

Flight Certification

Flyover Noise Source Identification

Static Engine Noise Certification

Underwater Acoustic Ranging

Self-Noise Monitoring Systems (SNMS)
Electroacoustics
To deliver quality sound, it is essential to analyze the sound produced and captured during R&D. A multitude of parameters are critical to authentic sound reproduction.

Telephone Headset And Handset Testing

Testing Of Hands-Free Devices

Headphone Testing

Hearing Aid Testing

Loudspeaker Testing

Smart Speaker Testing
Machine Analysis and Diagnostics
Machine analysis and diagnostics help you identify energy emissions caused by noise and vibration, which could explain inefficiency in machinery.

Order Analysis

Machine Diagnostics

Health and Usage Monitoring Systems (HUMS)

Gas Turbine Testing
Vibration Testing and Validation
Through vibration testing we can condense a lifetime of stress and wear into a short period of time, reveal hidden design weaknesses and validate durability.

Durability Testing - Fatigue Testing

Shock and Drop Testing

Package Testing - Transport Vibration Simulation

Environmental Stress Screening - ESS

Mechanical Satellite Qualification Test

Buzz, Squeak and Rattle (BSR)
Structural Dynamics
Structural Dynamics is a type of structural analysis intended for the purpose of assessing how physical forces affect structural integrity and performance.

Operating Deflection Shapes (ODS)

Classical Modal Analysis

Ground Vibration Test (GVT)

Operational Modal Analysis (OMA)

Structural Health Monitoring (SHM)

Test-FEA Integration

Shock Response Spectrum (SRS)

Structural Dynamics Systems

Structural Dynamics Questions?
NVH - Noise Vibration and Harshness
The combined noise, vibration and harshness - NVH - is immediately apparent when car drivers assess the ‘feel’ of a vehicle.

NVH Simulation

CAE Simulation

Source Path Contribution - SPC
Room and Building Acoustics
Architectural Acoustics encompasses both building acoustics and room acoustics. From focusing on sound transmission through walls, doors and floors to improving and shaping the behaviour of sound inside a room.
Environmental Noise
By measuring and mapping environmental noise, and general noise pollution, we can limit the impact of noise on health, and improve the quality of life for humans and animals.

Urban Noise Pollution

Workplace Noise
Production Testing and Quality Assurance
Effective production testing ensures customer acceptance and maintains product brand value, production line yield and cost effectiveness by ensuring that finished products comply with the expectations set during R&D, that product quality is consistent and that root causes for faults are mitigated.

Production testing for automotive components
Product Research and Development
Measurement, development, troubleshooting, and documentation is intricate processes in product research and development - from spot testing to real-time analysis and data post-processing.
