- ONO SOKKI Integrating Sound Level Meter LA-1411
The LA-1411 Integrating Sound Level Meter conforms to the latest IEC / JIS standards while focusing on easy operation and cost effectiveness.
Three models of sound level meter LA-1411/1441A(Class 2) and LA-4441A (Class 1) are applicable to IEC 61672-1:2013, JIS C 1509- 1:2017. The all models can perform simultaneous measurement of seven sound parameters including equivalent continuous sound level without adjusting the level range corresponding to the sound fluctuation and display the selected parameters.
Integrating Sound Level Meter
Model:
LA-1411, LA-1441A, LA-4441A
Maker:
ONO SOKKI
Features
Simultaneous measurements of seven sound items including equivalent continuous sound level (Leq) and displays of measurement results to be selected.
Essential seven sound items for sound measurement including equivalent continuous sound level (Leq) can be measured at the same time, and also displayed to be selected. The LA series sound level meters greatly help the effective sound level measurement without any miss-measurement.
| • | Lp | time-weighted sound level |
| • | Leq | time-average sound level (equivalent continuous sound level) |
| • | LE | sound exposure level |
| • | Lmax | maximum time-weighted sound level |
| • | Lmin | minimum time-weighted sound level |
| • | Lpeak | peak sound level |
| • | LＮ | percentile sound pressure level |

Microphone can be separated from the main unit of sound level meter by connecting several exclusive coaxial cable(s).
Microphone can be separated from the main unit of sound level meter by connecting several exclusive coaxial cable(s). It enables measurement of great distance away.
Simple and easy data processing
Connecting the main unit of sound level meter with Windows-based PC via RS-232C or USB cable, the LA series can transfer the obtained measurement data to the PC easily and quickly, also can be operated and controlled remotely from PC with a software (user preparation).
(Excluding LA-1411)
Sound level meter Class 1LA-4441A Class 2LA-1411/1441A
The microphone is able to be used away from the main unit of sound level meter by using exclusive coaxial cable(s). Featuring curve-shaped body with minimum affects from sound reflection, easy-to-read and intuitive operating menu etc., our new sound level meters have greatly improved more than ever easier as ergonomically designed interface.
Moreover, LA-1441A/4441A sound level meters can transfer the measurement result to a PC with simple and quick operation via RS-232C or USB interface. The sound level meter can be controlled remotely from PC using software (user preparation).
