Echolocation is an interactive audio-sensory simulation designed to chart auditory perception parameters across standard clinical frequency sectors. By integrating gameplay coordinates with a real-time synthesis engine, this framework evaluates human thresholds without the cognitive fatigue typically associated with clinical pure-tone testing configurations.
The application maps sensory bounds across critical human audio bands (250Hz - 8000Hz). Users track moving graphic structures, stimulating dynamic focus while target auditory tones are triggered in the background. Performance results compile instantly, rendering visually onto a custom-mapped interactive diagnostic audiogram representation.
To generate a representative auditory threshold distribution sequence, execute the following parameters:
The sensory core runs on the native Web Audio API, implementing pure sine wave oscillators constructed programmatically at runtime. The diagnostic framework mimics standard Hughson-Westlake audiometric staircase algorithms (down 10dB after visual validation, up 5dB following a failure threshold).
This framework maps 250Hz, 500Hz, 1000Hz, 2000Hz, 4000Hz, and 8000Hz. Volume amplitudes map to an exponential dB range from 0 (nearly silent) to 100 (high volume). Touch coordination is fully decoupled from DOM frame loops via optimized canvas operations to achieve high-performance rendering benchmarks, minimizing latency.
