The "NVA L&S Calc" application module was specifically developed for psychoacoustic analysis of impulsive events, such as impacts, door closures, and others.

The software is capable of importing signals recorded in standard file formats, such as CSV, Uff58, Uff58bin, SDF, and others.

Through a series of user-configurable parameters, it can automatically read and analyze multiple events from both monaural and binaural recordings, extracting impulsive components and automatically calculating loudness and sharpness parameters.

It is also possible to replay the events and export the results in convenient ASCII file format.

The "NVA L&S Calc" application module is designed for psychoacoustic analysis of impulsive events, such as impacts or door closures, in sectors like Automotive, Aerospace and Civilian Engineering.
