About: Curiosity With Clear Explanations
Too often online, auditory illusions are shared as clickbait "ear-age tests" or mystical frequency cures. Signalstormediapand was built as a calm, well-lit alternative: a Perception Cabinet where curious listeners can observe strange acoustic phenomena and read what actually happens in the signal.
How We Document Every Experiment
Whether we are demonstrating a 1960s Bell Labs pitch paradox or tapping a stoneware mug full of bubbly cocoa, every exhibit follows four rules:
- Start with a concrete observation: Describe what a listener notices first in plain, inviting language.
- Specify the signal and listening conditions: State the exact frequencies, channel routing (mono vs. dichotic stereo), and whether headphones or speakers are helpful.
- Separate physics from perception: Distinguish between physical changes in air pressure (like room standing waves or spring dispersion) and neurological interpretations (like virtual pitch or phonemic restoration).
- Respect the listener’s ears and autonomy: Never autoplay sound, always provide written equivalents for readers browsing in silence, and never imply that perceptual differences measure hearing health.
Primary Scientific Literature We Reference
Our notes draw directly from foundational peer-reviewed work in psychoacoustics and experimental acoustics, including Hermann von Helmholtz’s On the Sensations of Tone (1863), Lord Rayleigh’s Duplex Theory of localization (1907), Harvey Fletcher’s critical-band studies (1940), Roger Shepard’s circular pitch study (1964), Diana Deutsch’s work on musical illusions (1974–1995), Frank S. Crawford’s allasonic fluid measurements (1982), and Albert Bregman’s Auditory Scene Analysis (1990).
