Services
NVH testing, analysis and engineering services.
Specialist measurement, development and consultancy support
for automotive and wider engineering applications.
Structural Analysis
Modal Analysis
Modal analysis identifies the natural frequencies, mode shapes
and damping characteristics of structures, components and
assemblies.
By understanding how a structure responds dynamically, we can
identify resonances, investigate vibration issues and provide
engineering information to support development and optimisation.
Acoustic Analysis
Noise Characterisation
Measurement and analysis used to identify, quantify and understand
noise sources and unwanted acoustic behaviour.
Testing can be used during development, benchmarking and
troubleshooting to identify dominant frequencies and operating
conditions before targeted engineering changes are made.
Powertrain Development
Full Powertrain Test Platform (FPTP) NVH Evaluation
Controlled NVH evaluation of complete powertrain systems under
representative operating conditions.
This allows engineers to investigate noise and vibration behaviour
in a controlled environment while supporting development,
comparison and troubleshooting work.
Vehicle Testing
On Road / Track Testing
Vehicle NVH measurements performed on-road or on-track under
real operating conditions.
Testing in the vehicle’s intended environment provides valuable
information about real-world acoustic and vibration behaviour
across different speeds, loads and surfaces.
Exterior Noise
ISO 10844 Pass-by Noise
Pass-by noise measurement and development work using
ISO 10844 compliant test environments.
Measurement can support vehicle development, source
identification and investigation of exterior noise behaviour
under repeatable test conditions.
Controlled Vehicle Testing
2WD / 4WD Dynamometer Testing
Controlled 2WD and 4WD dynamometer testing for vehicle and
powertrain noise and vibration analysis.
Dynamometer testing allows repeatable operating conditions to be
reproduced while detailed NVH measurements are collected during
development and troubleshooting programmes.
NVH Analysis
Transfer Path Analysis
Transfer Path Analysis investigates the routes through which
vibration and noise travel from individual sources to a vehicle,
structure or measurement position.
Understanding these paths helps determine which sources and
structural connections make the greatest contribution to an
observed NVH problem.
Structural Testing
Point Mobility / Dynamic Stiffness
Measurement of structural mobility and dynamic stiffness to
understand component, mounting and structural response.
These measurements can support the optimisation of vibration
isolation and provide valuable data during component and vehicle
development.
Acoustic Testing
ISO 3745:2012 Semi-anechoic Chamber Sound Power Measurements
Controlled sound power measurements performed within a
semi-anechoic environment.
The controlled acoustic environment provides repeatable
measurement conditions for evaluating components, assemblies
and other noise-generating systems.
Noise Source Identification
Acoustic Camera Measurement and Analysis
Acoustic camera measurement creates visual sound maps that help
identify and locate dominant noise sources.
This provides an intuitive way to investigate complex acoustic
behaviour and can significantly speed up noise source
identification during development work.
Electric Vehicles
Electric Vehicle Artificial Sound Quality
Evaluation and development of artificial and enhanced sounds
for electric vehicles.
AVA can support objective measurement and subjective evaluation
as manufacturers develop distinctive and appropriate acoustic
characteristics for electric vehicles.
Vibration Isolation
Mount Stiffness Optimisation
Measurement and optimisation of mounting stiffness to improve
vibration isolation and refinement.
Understanding the dynamic behaviour of mounts allows component
isolation and structural performance to be developed more
effectively.
Development Testing
Component / Sub-system Testing
Flexible NVH testing for components and sub-systems to support
development, benchmarking and troubleshooting.
Test programmes can be developed around individual engineering
requirements rather than relying on a one-size-fits-all
measurement approach.
Specialist Recording
Vehicle Noise Recording for Commercial Use
High-quality recording of vehicle and mechanical sounds for
commercial, media and engineering applications.
Specialist instrumentation and engineering knowledge can be used
to capture clean, repeatable vehicle recordings in appropriate
operating conditions.
Component Acoustics
ISO 13487:2019 for Heat Exchangers
Acoustic testing and measurement of heat exchangers in support
of ISO 13487:2019 requirements.
Controlled measurements can be used to quantify acoustic
performance and support product development and comparison.
Non-Automotive Testing
ISO 5395-1:2013 for Garden Equipment
Noise and vibration testing for garden equipment in support of
relevant ISO 5395-1:2013 requirements.
AVA’s NVH measurement capability can be applied beyond automotive
engineering to a wide variety of machinery and equipment.
