The saved data can be analysed on the PDA itself, transferred to the supplied PC software or even exported to other analysis system
Bruel and Kjaer's PDA-based SoNoScout NVH makes binaural recording and analysis is much simpler and quicker.
The SoNoScout system is designed to record and analyse binaural sound for NVH development applications.
It is suitable for testing of prototype or design performance changes, benchmarking competitor vehicles and evaluating vehicle behaviour during on-road tests.
Recording is carried out via two microphones which are mounted on to a pair of folding headphones.
Immediately after recording, the stored data is available for replay and analysis.
The saved data can be analysed on the PDA itself, transferred to the supplied PC software or even exported to other analysis systems, such as Bruel and Kjaer's Pulse data analyser.
The PDA's display has large, simple icons making it easy - and safe - to control the start and stop of recordings, even while the operator is driving.
Keith Vickers, Technical Specialist for Bruel and Kjaer UK said "It contains analogue and digital sound cards for recording with the supplied microphones or a head and torso simulator".
"It simultaneously stores audio and positional data through an included Global Positioning System (GPS) device".
"As well as route mapping, this also allows the user to plot vehicle speed during the recording".
"The audio and vehicle performance data recorded by SoNoScout can also be used for analysis with Bruel and Kjaer's Pulse NVH vehicle simulator, as both systems are fully compatible".
The entire SoNoScout NVH system is contained in one rugged transport case and the main components are compact enough to fit inside a jacket pocket.
Bruel and Kjaer UK is also running the free Ultra Portable Sound Quality interactive training course, which covers sound quality metrics, measurement procedures and post processing.
