1. The B & K Story http://www.bkcomp.com

B& K began in 1981 with a simple philosophy: Make great soundingaudio components and keep prices low. Critics took notice, and ravereviews have followed the introduction of every new product. Today, B& K is one of the premier manufacturers of high end audio and hometheater components. We're proud to say that everything we make isdesigned, engineered and manufactured at our Buffalo, New Yorkfacility. But there's more to B & K than superior sound atreasonable prices. We believe in creating products that are simple touse today and upgradable tomorrow. Because, in the end, our goal is tocreate friendships and long term relationships with our customers andour dealers. Once you buy B & K, you'll never need to own any otherbrand. We want to earn your loyalty. It's that simple.

2.挪威Norsonic公司 http://www.norsonic.com/

Noise affects all our lives......but the problems can be solved only if we accurately measure the noise.

Startingwith an order to the Anglo-French supersonic Concorde project, we havefor more than 33 years used our technical expertise to develop soundinstrumentation of high precision and quality. Combining advancedtechnology and user-friendliness, we focus on the user and applicationsrather than on the complexity of the instrument.

Our closerelationship with our main clients and distributors in more than 20countries throughout the world, ensures contact with users and thedevelopment of products in parallel with the emerging needs for them.

Basedon our "all-in-one" philosophy, we develop complete solutions which canbe compared to portable laboratories. This means that the user can makemeasurements, analyse the data and print out the results on-site.

Ourretrofit policy is a fundamental part of our business concept. Most ofour instruments are of modular design. If new standards or newtechnology call for an update of the instrument this can easily becarried out by the factory or one of our local service centres. Hence,early customers have an instrument as modern as our newest customers.

Theamount of concern for noise abatement and acoustics vary around theworld, based on health and environmental concerns, governemtregulations and citizen demand. We are encouraged to see that the needfor high quality acoustical instrumentation is growing and the resultswill mean a quieter and more enjoyable world

LMS introduces LMS PolyMAX - 2/9/2004
New Integrated Modal Parameter Estimator Outperforms all Available Estimation Techniques

LMSInternational introduces LMS PolyMAX, the new integrated modalparameter estimator that outperforms all known estimation techniquesavailable on the market today. PolyMAX drastically simplifies theselection of poles, typically the most difficult step in modalanalysis, by offering crystal-clear stabilization diagrams. Theinnovative PolyMAX curve fitter not only allows faster modal analyses,it also introduces a reliable solution to solve problems other modalanalysis techniques were unable to tackle. LMS introduces PolyMAX aftermultiple years of research and validation efforts, in cooperation withthe University of Brussels (VU

Whilethe application range for modal testing and analysis is continuouslyexpanding, the complexity of the tested structures is also increasing.Modal analysis is nowadays intensively used to assess the structuralbehavior of complex structures with high damping, such as a trimmed carbody. The quality of the modal parameter estimation technologies thatwere available so far did not provide satisfying results for thesehighly damped structures. Customer tests on fully trimmed car bodymodels now show that the new LMS PolyMAX poles selection method is mucheasier to use and dramatically faster. In addition, it producesuser-independent results and provides much clearer information on thestructural behavior of the model. The stabilization diagrams PolyMAXgenerates really speak for themselves, as they permit theidentification of a higher number of modes, each with a highly accurateestimation for frequency, damping and mode shape.

Thisinnovation in modal parameter estimation also represents a key enablerin the updating and validation of virtual simulation models. Theinsight provided by the test-based model through LMS PolyMAX delivers afaster, and much more accurate simulation stage earlier in the designcycle.

LMS PolyMax is integrated in the LMS Test.LabStructures suite, a complete solution for modal analysis, combininghigh-speed multichannel data acquisition with a suite of integratedtesting, analysis, and reporting tools. LMS is renowned for its modaltesting experience and scalable solutions, from supporting impacttesting on small structures up to large test campaigns using multipleshakers and hundreds of measurement channels.

揑n an area wheremany critics claim no substantial advances were to be expected, the newLMS PolyMAX method brings a revolutionary modal parameter estimationtechnique that is easy to use, quick to perform, and substantiallyreduces operator-dependant judgment? commented Filip Pintelon CorporateVice-President and General Manager Test Division at LMS. 揥ith PolyMAX,LMS confirms its track record of introducing innovative solutions thatincrease the productivity of test-based engineering and that enablesengineers to analyze ever more complex structures.?/P>

辛苦了，如果广告贴，
最好把你的产品的主要特点用中文写一下，
这样才显示出sales的作用。

For the NVH instruments, B&K and LMS nay be the best in the world.

belvis · 发表于 2008-1-8 11:22

适合自己的才是最好的！
每家公司的产品都有各自的优缺点和适用场合，需要多方面的去评估

hyl2323 · 发表于 2008-1-8 14:02

happyman，我觉得bk的硬件可靠性高，LMS的软件友好，在汽车NVH的应用方案做得较为系统。我也是在斟酌选择哪家？主要做模态试验和耐久。您能给点意见么？

cqu999 · 发表于 2008-1-11 14:06

LS要是做模态,建议用LMS.

jarquine · 发表于 2008-1-11 15:04

建议大家版上做个详细比较，很多单位想采购

楼主所说的B&K好象是另一家B&K,是做音频设备的,象功放一类的东西.
大家常说大噪声实验及分析的B&K的网址是:
http://www.bksv.com/,
我也是今天才发现的还有另一家B&K,:-).
