Introduction

Worker exposure assessment is easier when measurements, profiles, workers, machines and PPE data stay in one structured project. NS1 Workers Protection Module supports consultants and safety teams in noise and vibration risk assessment inside a company, with guided workflows for daily and weekly exposure evaluation.
 
The software manages homogeneous groups of workers and supports task-based and job-based analysis according to ISO 9612. It integrates global data and time histories, provides masking functions for abnormal noise events, and automatically recognizes constant, cyclical, fluctuating and impulsive noise sources with conformity checks to UNI 9432.
 
PPE selection is built into the workflow through customizable databases, real-time attenuation display and SNR, HML and OBM calculation methods. Extended uncertainty can include instrument, positioning and sampling components according to ISO 9612, while automatic reports, charts and summary tables help identify workers most at risk.

Features

Worker group management

The module manages homogeneous groups of workers, company data, worker sheets and machine databases within a project.

Exposure workflows

Daily and weekly exposure calculations are available for noise and vibration data, with task-based and job-based approaches.

Profile post-processing

Time profile data can be processed with multiple masking functions to exclude unwanted events from calculations.

Noise source classification

The software automatically identifies impulse noise and classifies sources as cyclic, stationary or fluctuating.

PPE management

Advanced PPE management with attenuation display to support hearing protection selection. Includes customizable PPE database, efficiency evaluation, double PPE configuration, and calculation methods based on SNR, OBM, and HML (including impulse noise).

Project Data organization

All-in-one project organization with tree structure for fast access to measurement data. Integration of Word documents and images for complete reporting, with unified management of noise and vibration data.
