LMS Sound Camera
Fast and Versatile Sound Source Localization
LMS Sound Camera hardware and software is a member of the LMS sound source localization product portfolio, part of the Simcenter solution. This modular, high-quality digital microphone array offers an instant overview of sound sources on any noise-generating object. Together with the dedicated software, it is a great tool for both occasional and experts users to help confirm that they are working on the right problem.
Using the LMS Sound Camera Digital Array minimizes the time spent in tracking down sources which contribute to unwanted noise. The system is quickly set up, even by novice users. All electronics are integrated in the array, connected by a single cable to the computer. Its design is suitable for a wide frequency range, both in the far-field and near-field. By adding or removing the short or long arms, which can be done in one click, users can work on objects of different sizes and at different distances.
The dedicated LMS Sound Camera software shows results immediately after starting up. This single-sheet application delivers clear, graphical results that are easy to interpret and share. The real-time data can be compared side-by-side to a reference hologram any time, clearly emphasizing the issue and the impact of any design modification.
For increased engineering insight, the LMS Sound Camera Digital Array can also be used together with the LMS Test.Lab software. With 4 built-in auxiliary data channels or a parallel connection to the LMS SCADAS front-end, the localized sources can be correlated with any NVH attribute from a synchronized, multi-channel measurement. For even more advanced processing, engineers can apply state-of-the-art Sound Source Localization (SSL) techniques, such as improving spatial resolution with irregular Near-field Acoustic Holography (iNAH), deconvolution or quantification of sources, all on the LMS Test.Lab platform.
Whether troubleshooting the annoying buzz of an office printer, locating the origin of an upsetting noise problem at a manufacturing site or supporting the acoustic engineering process of an electrical engine, LMS Sound Camera enables customers to enhance product acoustic design.
Versatile and robust digital microphone array
With LMS Sound Camera Digital Array, performing efficient acoustic troubleshooting becomes independent from distance or object size. The same array can be used in the field one day, and in the lab next day, by different teams for a multitude of sound source localization tasks. All electronics are integrated in the array, making an external data acquisition system unnecessary. To improve spatial resolution performance, the LMS Sound Camera Digital Array easily extends to a wider array with optional short or long arms, adding respectively 4 or 8 digital microphones each.
Accelerate acoustic troubleshooting
From unpacking to first results, the LMS Sound Camera is set up and ready in a couple of minutes. It permits instant, reliable localization of any stationary, transient or impulsive sound. The intuitive software records data and in parallel gives clear, unambiguous results. Previewed data remains available for A/B comparison of results, validation and efficient reporting with pictures and videos.
Increase engineering insight with LMS Sound Camera in LMS Test.Lab
The LMS Sound Camera Digital Array can also be directly connected to LMS Test.Lab HD acoustic camera application, enabling the use of 4 built-in auxiliary data channels that support AC and ICP input sensors. If, on top, additional channels are required, one can combine the LMS Sound Camera Digital Array with the LMS SCADAS Mobile hardware, enabling synchronized multi-channel data acquisition.
To further improve the localization results, engineers can rely on the data post-processing capabilities of LMS Test.Lab platform, such as irregular Near-field Acoustic Holography (iNAH), far-field deconvolution, order analysis or benefit from productivity increasing tools, such as batch processing.
