Low Noise Microphone MI-1282M10
For noise reduction measures in EVs and home appliances. A low-noise measurement solution that accurately captures subtle sounds in the 10 dB range (A-weighted), which is difficult to measure with standard microphones.
■Limit performance of self-noise at 4.5 dB, with the simplicity of direct BNC connection. In recent years, the challenge of "noise reduction" has become unavoidable in the development of home appliances and EVs (electric vehicles). This product is an ultra-low noise measurement microphone that achieves an overwhelming low noise performance with a self-noise level of 4.5 dB (representative value). By adopting the CCLD (Constant Current Drive) method, which eliminates the need for expensive external amplifiers and dedicated power supplies that were essential in conventional low-noise measurements, it allows for direct connection to the analyzer with a single BNC cable, simplifying the measurement system and reducing costs simultaneously. <Main Features and Benefits of Implementation> - Accurately captures micro sounds in the 10 dB range (A-weighted). - CCLD method and direct BNC connection eliminate the need for amplifiers. - TEDS compatible to eliminate setup errors. - Versatile support from field measurements to R&D.
basic information
【Product Specifications Overview】 ■ Overwhelming Low Noise Performance Achieves a self-noise level of 4.5 dB (typical value). It accurately captures low noise levels around 10 dB (A-weighted) that would typically be buried in noise with conventional microphones. ■ Simple System Configuration (CCLD Method) Adopts a constant current drive (CCLD) method. It can be directly connected to the analyzer with just one BNC cable, without the need for external amplifiers or dedicated power supplies. This simplifies the measurement system and reduces costs. ■ Automation of Settings (TEDS Compatible) With the TEDS function, individual information such as sensitivity is automatically read just by connecting the device. This eliminates the hassle of manual input and setting errors, significantly shortening preparation time for measurements. ■ High Mobility and Versatility When combined with battery-powered devices like the DS-5000, it enables laboratory-quality field measurements even in vehicle interiors or outdoor environments where securing power is challenging.
