Overview
Acoustic Explorer is a simulated laboratory sandbox designed to model how relative audiological sensitivity assessments can be seamlessly integrated into interactive digital environments. Conventional audiometric profiling relies on dry, manual, pure-tone assessments. This platform transforms clinical paradigms into a dynamic visual mapping system where the user interacts with standard baseline assets alongside low-visibility acoustic targets. In this relative framework, capturing auditory cues dynamically adjusts the output gain to trace sensory thresholds across predefined frequencies.
How To Use
Follow these progressive, structured instructions to explore the interactive profiling workspace:
- Stereo Verification: Put on stereo headphones and verify correct routing (Left/Right balance). Ensure operating system output levels are set comfortably.
- Active Maneuvering: Tap directly on the left, center, or right thirds of the active radar screen to reposition the probe, or use the A/D / Arrow keys on desktop keyboards.
- Tracking Visual Beacons: Standard golden beacons are visible across all navigation channels and serve as target controls. Faint, pulsating blue (Left Channel) or red (Right Channel) beacons represent auditory targets. When they pass down the screen, rely on panning cues to safely guide your path.
- Automated Inactivity Trigger: If you remain inactive for 45 seconds, the application transitions into an automated "Sandbox Demo Mode" with a synthetic autopilot sweeping through visual anomalies, keeping your physical score intact. Touch any control to resume manual play instantly.
Technical Details
Acoustic Explorer processes sound synthesis on the client-side utilizing the unified Web Audio API. Key technical integrations include:
- Logarithmic Gain Controls: Audio amplitude translations apply standardized decibel conversions mapped to custom relative sound pressure levels, mitigating raw hardware clipping.
- Spectral Resolution: Real-time sine wave generators synthesize core diagnostic frequencies (250 Hz, 500 Hz, 1000 Hz, 2000 Hz, 4000 Hz, 8000 Hz).
- Input Integrity: The main visualizer canvas implements specialized touch-action rules to ensure user drags do not interfere with system-wide vertical view transitions.
- Logarithmic Plotting Layout: The rendering framework features inverted Y-axes mimicking physiological clinical designs, plotting zero relative attenuation at the absolute ceiling.
Future Directions
Future development phases aim to explore absolute calibration profiles using biological baseline protocols (such as standardizing baseline tone perception against average noise floors). Incorporating real-time microphone analysis via ambient analysis nodes could also evaluate ambient noise levels and issue warning notifications if background thresholds interfere with system accuracy.
