LMS Acoustics Testing

Scalable solutions for spot-on sound testing and analysis - Product sound and sound quality are key aspects of product perception. How a product sounds plays a critical role in conveying the right message about its functionality, comfort, overall brand image and its quality. Regulations and competitive pressure have forced manufacturers to keep noise levels within limits and meet increasingly stringent sound standards. Sound engineers look for more productive testing and analysis solutions to quickly and effectively identify root causes of existing sound issues and help them effi ciently design products that transmit the right brand message. Answering the call for a variety of acoustic techniques In the world of sound engineering, “ one size fits all” is not applicable. This is not surprising since sound engineering addresses an extensive range of sound issues in everything from cars to gardening equipment, dishwashers to snowmobiles, and aircrafts to personal computers. Depending on the industry segment and company size, sound engineering might be performed by sound specialists who have the latest techniques and equipment at their disposal or it might simply be a one-engineer operation with a limited budget. LMS Acoustics offers a complete and unique suite of software and hardware solutions for acoustics testing and analysis in specific domains such as straightforward acoustic analysis, material and component testing, sound power and pass-by noise testing, sound source localization, vibro-acoustic engineering, and sound quality and brand sound engineering. Scalable according to project requirements, each solution offers task-specific advantages in terms of return on investment. For more complex root cause analysis and tried-and-true countermeasurements, LMS experts can provide advanced acoustic and vibro-acoustic engineering tools and services. Getting to the bottom of it For years, sound experts and engineers have been experimenting with acoustic techniques to find the best possible way to meet sound requirements and solve sound issues. A first step is to gain an in-depth understanding of how sounds are composed and which aspects contribute to it. Once the sound attributes are identified, they can be linked to physical components. The LMS acoustic solutions directly address a wide variety of challenges that sound experts and engineers daily face. Acoustic techniques for spot-on sound testing and analysis: • Acoustic analysis: multi-channel sound level meter and octave analysis • Material and component testing • Sound power and certification measurements • Pass-by noise testing • Sound source localization ( sound intensity, beam-forming, holography & focalization) • Sound quality and brand sound engineering • Vibro-acoustic engineering: TPA and acoustic source quantification LMS acoustic solutions throughout the product development cycle: • Bench-marking and brand sound engineering • Sound design and target-setting • Scalable advanced techniques for product refinement, sound engineering and trouble-shooting • Qualification and certification • In-field and in-house certification and testing Meeting sound objectives The LMS Acoustics portfolio integrates all the basic functionalities that acoustics and test engineers require to assess sound. The LMS Acoustics suite provides a comprehensive, verstatile and easy-to-use solution that covers a wide variety of sound engineering tasks such as tracking overall sound pressure levels, determining spectral content, or create metrics to quantify the perceived level or articulation index to evaluate speech intelligibility - to name just a few. So whether you are an acoustics expert who relies on the latest analysis techniques or an occasional user who needs high quality and reliable results, LMS Acoustics is a perfect all-around acoustic measurement system. LMS Acoustics as an acoustic measurement system: • Multi-channel sound level meter • Parallel real-time octave & narrow-band FFT analysis • Loudness • Articulation index • Time recording Selecting the right materials and components More and more engineers are acknowledging the importance of acoustic material testing and its impact on the quality and performance of the final product design. The way in which acoustic material absorbs and reflects sound can have as much impact on the design as the choice of the material itself. LMS Acoustics offers a full spectrum of tools to study and examine the sound behavior of various material and components and help determine how they would affect the overall sound of the final product. LMS Acoustics for material & component testing: • Acoustic absorption and impedance • Sound transmission loss • Acoustic transparency of components using sound source localization • Impedance tube • Room methods Conforming to sound power standards Declared sound power is a key brand driver in many competitive sectors – from commercial power tools to construction equipment and off-road vehicles. Meeting or missing certification standards can make all the difference between a successful product launch and a failure. This is also applicable to subcomponents, like engines that need to be tested and benchmarked for sound power objectives. The LMS Acoustics portfolio provides several sound power solutions appropriate for multiple standards and adaptable to industry and customer-specific testing procedures for maximum productivity. LMS Acoustics for sound power testing: • Pressure-based solutions • Intensity-based solutions • Array-based acoustic holography solutions Supporting pass-by noise standards With the increase in global mobility, urban pass-by noise regulations are becoming more and more stringent – this goes from everything to cars and trucks to scooters and motorcycles. Test requirements in the latest standards are much more complex and require more intelligent systems to perform productive and reliable tests. LMS Acoustics offers a complete range of tried-and-true pass-by noise solutions for a variety of testing standard environments for certification or engineering refinement. LMS Acoustics for pass-by noise testing: • Outdoor solution • Indoor solution • Certification and engineering refinement Shaping the right sound quality Sound is subjective, which is why it is so tough to define an “ ideal sound” . LMS Acoustics offers a variety of solid solutions to help determine the best possible sound – wherever required in the development process cycle. Scalable to every need, LMS Acoustics can be used for a variety of sound quality applications. LMS Acoustics for sound quality: • Objective assessment using psycho-acoustics and other metrics • Subjective evaluations • Source identification and troubleshooting using replay & filter • Virtual sound design & advanced refinement Discovering the origins of sound The principle mission of sound engineers is figuring out where the sound is actually originating, which is why sound source location techniques are so common. They can also be incredibly labor intensive. To significantly save time and resources, LMS has designed a number of cutting-edge sound source localization solutions, including high-definition acoustic cameras, to increase overall testing productivity as well as other techniques that meet different required criteria such as frequency range, accuracy, cost and time pressure. LMS Acoustics for sound source localization: • Sound Intensity ( pressure-pressure & pressure-velocity probes) • High-definition acoustic camera • Acoustic beam-forming, acoustic holography & focalization • Far-field & near-field techniques for free-field & vehicle interiors • Stationary and transient events • Hybrid approach using inverse BEM Pinpointing the root cause Efficient design modification in complex mechanisms can only be obtained with an in-depth understanding of the system. In this case, it is important to know what are the real sources and transfer paths and how do they contribute to the sound. LMS is known for its vibro-acoustic engineering expertise. Finding the root cause of noise issues through transfer path analysis can help users make important design decisions, saves time and costs and improves the efficiency of the entire development cycle.
