SoundPLANmanda Features — Complete Occupational Noise Mapping Capabilities

SoundPLANmanda provides a complete toolset for occupational noise assessment — from 3D facility modeling and noise source characterization through to worker exposure calculation, hearing protection zone mapping, and professional regulatory reporting. Here is a detailed breakdown of what SoundPLANmanda can do.

3D Facility Modeling

• Import CAD floor plans (DXF/DWG) as the basis for the facility model
• Model machinery, equipment, and production processes as individual noise sources
• Define walls, floors, ceilings, and partitions with acoustic properties
• Model multiple floors and mezzanines in multi-story facilities
• Use the built-in equipment noise database for common machinery

Noise Mapping

• Color-coded 2D noise maps across the entire facility floor plan
• Vertical cross-section noise profiles
• Customizable noise level contour intervals
• SPL maps at any defined height (e.g., ear height of 1.6 m)

Worker Exposure Assessment

• Define worker tasks, locations, and daily time allocation
• Calculate daily noise exposure level (LEX,8h) per worker or job role
• Calculate weekly noise exposure (LEX,w)
• Flag workers exceeding lower (80 dBA) and upper (85 dBA) action values
• Support for task-based assessment approach (ISO 9612)

Compliance & Reporting

• Professional compliance reports for ISO 9612, EU Directive 2003/10/EC, and OSHA
• Hearing protection zone maps for signage and zone management
• Before/after scenario comparisons for engineering controls
• Export maps and data to PDF, Word, and Excel for reporting

Engineering Controls Modeling

• Acoustic enclosures — Model complete or partial machine enclosures; calculate the insertion loss and resulting reduction in worker exposure
• Acoustic barriers and screens — Define line-of-sight barriers between sources and worker positions; calculate attenuation by diffraction
• Room absorption — Add acoustic absorption to reverberant spaces and observe the reduction in noise levels throughout the facility
• Source substitution — Replace a noisy machine entry with a quieter alternative and immediately see the impact across the facility model
• Relocation studies — Move machinery or worker workstations within the model and re-calculate exposure without re-measuring

Integration with Measurement Data

SoundPLANmanda is designed to work alongside field measurement data, not replace it. Measured noise levels from individual machines can be imported as sound power levels and used as inputs to the facility model. This hybrid approach — combining physical measurements with 3D propagation modeling — produces more comprehensive and accurate assessments than either method alone. It also means your facility model becomes a permanent asset that can be updated as equipment changes, without requiring a full repeat of the measurement survey.

Data Import and Export

• CAD import — DXF/DWG floor plans as the basis for the facility geometry
• Sound power data — Manual entry or import of measured sound power levels per source
• Report export — Maps, tables, and compliance documentation to PDF, Word, and Excel
• Image export — High-resolution noise maps for presentations and regulatory submissions
