These sound level meters were designed with an emphasis on “measuring while listening to sound” in addition to the original features of measurement and calculation. By adding various options, the LA-3000 can be upgraded to an analyzer, a recorder, and a comparator, performing more than just a sound level meter.
You can check the proper recording of data and the condition of the object via headphones, and see the analysis waveform on the large easy-to-see screen in order to carry out reliable measurement confidently at a site that does not permit any failure. Measurement, recording, analysis, and checking can be performed by a single item of equipment, thereby improving the measurement efficiency substantially. For more detailed analysis, analysis software made by Ono Sokki is useful such as waveform analysis, sound quality evaluation, or fluctuation sound analysis. |
