Trident – Sound Level Analysis

Trident’s basic operational mode is the sound level meter mode. In this mode, Trident provides A-weighted and Linear Sound Level readings and, optionally, can provide 1/N octave band levels (1/1, 1/3, 1/6, 1/12 and 1/24 octave). The sound level meter mode provides a free running, exponential averaging real time analyzer operating mode and an Leq averaging measurement mode. Max Hold mode allows for detection of the maximum A-weighted and/or 1/N octave band levels obtained during an acquisition.

Trident’s scalable licensing allows users to purchase only the features they need for their measurement program, making Trident and National Instruments USB hardware an affordable option to a basic sound level meter for applications requiring only Awtd and/or 1/N octave analysis.
