Title:

User Calibrated Frequency Mapping Headset

The User Calibrated Frequency Mapping Headset is a Digital Signal Processing (DSP) driven system designed to personalize audio playback for individual listeners. Traditional headphones often rely on fixed equalization and responsive microphones that fail to account for unique hearing variations and dynamic acoustic environments. This project addresses these limitations by implementing a sub-60 second hearing calibration test that measures a user's audibility across 41 different frequencies from 30hz to 20kHz, which correspond to a normal human’s hearing range. This test generates a hearing profile of activated and deactivated frequencies. These frequencies go to the filter system which is composed of Finite Impulse Response (FIR) digital filters using Kaiser window functions, that amplify heard frequencies and dampen unheard ones. System control is done via a terminal interface, and embedded C code for signal processing on an ESP32-S3 microcontroller. This combined system ensures consistent audio clarity and adaptive cancellation based on the environment a person is in.
