OtoFit

Calculate hearing aid gain targets from audiometric threshold data

Health AIPaid

OtoFit computes prescriptive gain targets using NAL-NL2 and DSL v5.0 fitting formulas from pure-tone audiometric thresholds. The tool generates insertion gain curves for mild through profound hearing losses across speech banana frequencies and calculates maximum power output limits to prevent loudness discomfort. Real-ear-to-coupler difference corrections adjust targets for individual ear canal resonance characteristics.
