<JIS Z 8731 "Description and measurement of environmental noise" >
Please refer to also ISO 1996

• We can easily perform FFT analysis of the noise which is generated from home appliances or the like by sound level meter.
• After installing LA-0703 FFT Analysis Function (option) to the LA-7500, perform FFT analysis of the noise under measurement. The maximum of FFT analysis frequency is at 25 kHz.
• All measurement data of the LA-7500 precision sound level meter can be stored in SD card. By connecting the main unit of sound level meter to the PC via USB interface or inserting the SD card into the card slot of the PC, the stored data can be transferred without any exclusive software. You can perform the measurement data freely as secondary processing with the spreadsheet software etc.
• Input of the AC output signal from sound level meter to FFT analyzer enables to perform FFT, 1/1 and 1/3 octave, and level trend analyses. The recording and playback analysis maximum of 4 GB can be performed by the DS-3000 series with optional DS-0351 throughput disk function.
