LMS is a complete set of sound analysis system with reasonable price examples, which can provide high quality and quantity for practical applications. Whether your purpose is professional audio system, home audio system, car audio, or contract audio engineering,


LMS are ideal tools for development and testing. No other measuring tool today offers so many great features and functions at such a low price. LMS electroacoustic testing system is a product of the U.S. LinearxSystem company. Because of its early appearance compared with similar products in the world, it has been more popular in the field of electroacoustic in China, and is a set of testing system with complete performance and reasonable price. LMS offers a number of computer-based features that are particularly focused on meeting the unique requirements of speaker development. It USES the burst sound technique to obtain a good frequency response curve. It can obtain many electroacoustic parameters of the loudspeaker in a short time, and is the right-hand man in the deb ing of frequency divider.

SOUNDCHECK 10.0 electroacoustic testing system


In general, the test system consists of a test software system running on a PC and external hardware. The biggest difference from the traditional testing instruments familiar to engineers is that the traditional testing instruments are integrated, the testing functions are fixed, and the customers are unable to achieve a series of different testing procedures and requirements, the computing speed is not comparable to the computer, and the function expansion is even more impossible. The computer-based test system takes full advantage of the powerful computing power of the computer, and functions are updated and test process changes are implemented.

SOUNDCHECK and different from other traditional electroacoustic testing system based on PC, such as the CLIO, LMS, DAAS and so on, the test system has served with their own hardware fixed external hardware (sound card, special amplifier, special test microphone, etc.), lack the flexibility of hardware collocation, the function is not enough to cope with the upper market out of acoustic products, such as test mobile phone, bluetooth wireless audio products would be totally lost, and so on.

SOUNDCHECK for external hardware is an open system, it makes the SOUNDCHECK can match different external demand of hardware to meet different customers including test system, such as demanding customers, can choose B&K hardware high-end test system, but also can choose good cost performance measurement test system hardware for your requirements. For example, we choose to use CLIO's QCBOX MODEL4 amplifier,CLIO's m-02 standard test microphone and American m-audio's DELTA 66 or DELTA 1010LT professional sound card to form an excellent system. This hardware collocation has been used by many well-known big factories, including domestic and Taiwan, HK thousands of sets, with excellent performance, stability and moderate price.

SOUNDCHECK's openness to external hardware makes it compatible with a variety of signal connections, which allows SOUNDCHECK to test wireless products.

In summary, only SOUNDCHECK test system can achieve one investment, namely, it can deal with various new products constantly emerging from customers. New test requirements do not need to purchase other test systems, but only add corresponding hardware. For example, to test bluetooth audio products, only need to add bluetooth communication adapter.

SOUNDCHECK electroacoustic testing system

SOUNDCHECK is a modular pc-based electroacoustic testing system, which can perform the testing of various parameters of electroacoustic products with high performance, or select appropriate software modules and hardware to build your specific application program. No matter the requirements for the simple operation of production line quality control (QC), or the requirements for R&D to have various extension functions, SOUNDCHECK can well meet and apply to the entire design and production process. By using a professional sound card on a standard PC, SOUNDCHECK is a new standard for better hardware updates for traditional electroacoustic detection devices.

Common platforms of R&D,QC and QA

SOUNDCHECK is an effective tool for development engineers. It USES effective measurement principles to ensure rapid measurement of frequency response, phase, sensitivity, distortion, directivity, impedance, beep, and Thiele-Small parameters in approximately a few seconds. In a separate test, it can complete the test, analyze the data, and compare the results with the predetermined limits. The software suite can form a series of pre-programmed test programs that are consistent with industry standards that can be extended indefinitely. This includes: TIA, ANSI, IEEE, ITU, etc.

SOUNDCHECK's advanced algorithms can even be tested at high speed and accuracy in extremely noisy environments, and the software can be configured to perform normal tests with one click, and can even be integrated into PLCs, barcode systems and external hardware and software systems.

Soundcheck electroacoustic testing system is the most powerful electroacoustic audio testing system on the market at present. It can be developed or produced by QC to test various kinds of loudspeaker, headset, microphone, sound, power amplifier and other parameters and performance.

The system is derived from the Soundcheck electroacoustic testing system of BK, Denmark, which is a modular pc-based electroacoustic testing system, which can perform the testing of various parameters of electroacoustic products with high performance. No matter the requirements for the simple operation of production line quality control (QC), or the requirements for R&D to have various extension functions,Soundcheck can well meet and apply to the entire design and production process. By using a professional sound card on a standard PC,Soundcheck is indeed a better replacement for the hardware of traditional electroacoustic detection devices.
