About this app

Hearing Loss Estimator helps you predict noise-induced hearing loss across different population groups using an advanced model aligned with ISO 1999 standards. By simply adjusting frequency, sound pressure level, and exposure time, you gain insights into potential hearing threshold shifts across various population percentiles. Transform complex noise exposure scenarios into understandable, data-driven forecasts to bolster prevention efforts and strategic planning. Test different "what if" scenarios seamlessly, compare different situations, and communicate risks with clear assumptions and results. Important: This app implements a model based on ISO 1999 with extended calculations. It is designed for educational, informational, and planning purposes only, not for personal medical decisions. Why it’s Valuable: • Standards-Aligned Forecasting: Leverage an ISO 1999-based model for reliable benchmarks. • Population Insights: Assess hearing threshold shifts across selected percentiles, highlighting varied risk levels. • Scenario Testing: Modify frequency, sound pressure level, and exposure duration to identify safer settings. • Prevention-Focused Analysis: Inform policy and safety planning with robust quantitative evidence. • Intuitive Visuals: View detailed per-frequency outcomes and overall impacts in a clear format. Key Features: • ISO 1999-based noise-induced hearing loss estimation • Customisable inputs: frequency, sound pressure level, exposure duration • Forecasts for hearing threshold shifts across population percentiles • Scenario comparison and dynamic "what-if" analyses • Easily interpretable visual summaries for reports • Local data storage with export options Ideal for: • Occupational safety and health professionals • Policy makers and educators • Industrial hygienists and acoustics experts • Researchers and students focused on NIHL risk Privacy: Your scenarios and results remain securely on your device. Disclaimer: Hearing Loss Estimator is not intended to diagnose or provide medical advice. Use it for informational and educational purposes. Consult healthcare professionals for clinical evaluations. What’s New: • Enhanced calculations aligned with ISO 1999 for more accurate forecasts • Improved visual representations and scenario comparisons • Performance enhancements and minor updates
