More details

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. 

-----

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).

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
