Automotive Audio Measurement
Any car audio, any measurement
SoundCheck offers simple, fast and accurate automotive audio measurement, from individual speaker components to complete in-vehicle infotainment and telematics systems. With interfaces to connect via Bluetooth, Lightning, USB and with individual MEMs devices, as well as analog connections, SoundCheck easily handles the complexity and demands of testing in today’s vehicles.
Automotive measurements include
- Speaker/system response
- Speaker/panel buzz, squeak and rattle
- Bluetooth audio performance
- Head unit and amplifier response & THD+N
- Microphone/microphone array response.
- Active noise cancellation effectiveness
- Spatial reproduction accuracy
Automotive Audio Measurement in R&D and Production
R&D Automotive Testing
In the R&D lab, SoundCheck is used for voicing the audio system to the car. This might include speaker positioning and equalization of the system for correct tonal and spatial balance including L/R and front/back balancing. It is also used for microphone positioning and directivity measurements, and noise cancellation performance with simulated and actual road noise.
At the end of the production line, SoundCheck offers a final audio QC check on the car. Initially a single measurement of frequency response and Rub & Buzz can be used to ensure that the audio profile measured in the car meets specifications. If there are discrepancies, each speaker can then be measured independently (including additional measurements such as polarity) to help identify the causes.
The microphone(s) can also be tested to verify directional response by performing simple directivity measurements using the car’s speakers.
