Overview of Sound Measurement and Related Products

* For measurements up to 100 kHz, please consider the CF-9200A/9400A or DS-5000 100 kHz unit. (Discontinued products) The CF-7200, DS-3000, and DS-2000 series 100 kHz units are also compatible.

* MI-1282M10 Low Noise Microphone Compatible Models

This software is compatible with the FFT analyzers DS-5000 series, CF-9200A/CF-9400A, and CF-4700A.
When used in combination with the FFT analyzer DS-3000 series, CF-9200/CF-9400 (without A), or CF-4700 (without A), sufficient performance may not be achieved depending on the conditions.
Modifications will be necessary when using these devices in combination. After modifications, some functions may be limited.

LA-4441A Integral mean (Class 1) Precision sound level meter	LA-1441A Integral mean (Class 2) Standard sound level meter	LA-1411 Integral mean (Class 2) Standard sound level meter

Features Sound level meter Class 1 (precision sound level meter) for noise analysis and product inspection. Equipped with a 10 ms IMPULSE time weighting characteristic to handle rapidly fluctuating sound levels. Level trend recording is possible with a saving interval of 1 ms (LP record function). Equipped with USB and RS-232C interfaces.	Features Sound level meter Class 2 (standard sound level meter) for measuring noise in work environments and ambient noise. Equipped with automatic measurement functions using timers and triggers. Level trend recording is possible with a saving interval of 1 ms (LP record function). Equipped with USB and RS-232C interfaces.	Features Sound level meter for machine noise levels and product inspection, Class 2 (standard sound level meter) Low-priced, high-performance models
LA-7700 High-performance (Class 1) Precision sound level meter	LA-7500 High-performance (Class 1) Precision sound level meter	LA-7200 High-performance (Class 2) Standard sound level meter

Features The adoption of a large 4.3-inch color LCD improves visibility, including the ability to overwrite text. By using USB bus power, it can be used for extended periods when combined with AA batteries. Simultaneous recording* is possible during frequency analysis. (Requires LA-0704 recording function) It is possible to compare all-pass sound (sound across the entire frequency range) and bandpass sound (sound within a specified frequency range). Infrasound measurement is possible (LA-0709 Infrasound measurement function required: only available on LA-7500)

SC-2600 sound calibrator	SC-2500A sound calibrator	SC-2120A sound calibrator

Features This acoustic calibrator conforms to JIS C 1515:2020 Class 1 and has a nominal sound pressure level of 94 dB. In addition to feedback control, it incorporates built-in correction functions for static pressure and temperature, resulting in stable sound output. For high-precision measurements using the low-noise microphone MI-1282M10, the use of this product is recommended. Acoustic calibration of low-noise microphones requires an acoustic calibrator with a nominal sound pressure level of 94 dB.	Features This acoustic calibrator conforms to JIS C 1515:2020 Class 1 and has a nominal sound pressure level of 114 dB. It generates a stable sound through internal feedback control. Because it generates a high sound pressure level of 114 dB, it is less susceptible to interference from ambient noise in environments such as factories and outdoors, allowing for calibration in the actual measurement environment.	Features This acoustic calibrator conforms to JIS C 1515:2004 Class 2 and has a nominal sound pressure level of 94 dB. It can also be used for simple operational checks. It employs a dynamic speaker design, resulting in a low price.
