- ONO SOKKI LA-7000 Series Sound Level Meter
Class 1 / Class 2 sound level meter with touchscreen operation
Contact Us
The LA-7000 Series sound level meter is a high-performance solution for professional noise measurement and acoustic analysis. Featuring a large color LCD with touch-panel operation, it enables intuitive sound level measurement while monitoring audio in real time.
With optional frequency analysis, sound recording, and sound quality evaluation, the LA-7000 Series supports Class 1 and Class 2 compliance for environmental noise, product testing, and advanced acoustic diagnostics.
・Sound level measurement with live monitoring (“measure while listening”)
・Environmental noise measurement and reliable field recording
・Octave band analysis (1/1 standard, 1/3 optional) and FFT narrow-band analysis (optional)
Features
• Touchscreen + color LCD for fast, intuitive operation in the field
• “Measure while listening” to confirm sound source and ensure recording integrity
• Multi-display modes: SINGLE / DUAL / QUAD for simultaneous weightings and values
• Expandable to analyzer + recorder via options (1/3 octave, FFT, recording/offline analysis)
• Reliable calibration history saving and export (CSV) for auditability
Model Selection
- LA-7700 (Class 1): High sensitivity for small sounds (10 Hz–20 kHz, A: 20–128 dB, self-noise ≤12 dB)
- LA-7500 (Class 1): Wide band, supports ultra-low frequency option (1 Hz–20 kHz with LA-0709)
- LA-7200 (Class 2): Environmental noise measurement (10 Hz–8 kHz)
Applications
• Anechoic room measurements (small sound evaluation)
• Environmental noise monitoring and compliance measurement
• Abnormal sound troubleshooting and sound source probing
• Machine noise diagnostics using octave/FFT frequency analysis
• Long-term site measurement with logging/recording
