Interactive simulations and resources for neuroscience education.
An automatic frequency sweep from 20 Hz to 32 kHz across intensity levels (0–70 dB relative). Maps your personal hearing threshold by holding the spacebar when tones are audible, visualized on an octave-scaled audiogram.
Launch SimulationExplore how auditory cortex neurons respond to combinations of frequency and intensity. Adjust tuning parameters to visualize receptive fields, characteristic frequencies, and response maps across the tonotopic axis.
Launch SimulationVisualize how the basilar membrane responds to sound. Adjust frequency, intensity, tuning sharpness, and damping to see traveling wave patterns and the tonotopic organization of the cochlea, with real-time audio output.
Launch SimulationDemonstrates how the brain uses microsecond timing differences between ears to localize sound. Adjust the ITD delay and mute individual ears to experience binaural processing and the precedence effect.
Launch SimulationExplore how level differences between the two ears contribute to sound localization, especially for high-frequency sounds. Adjust IID values and frequency to observe the head shadow effect and binaural level cues.
Launch SimulationPlays a looping melody while you adjust the strength of individual harmonics in real time. Demonstrates how the same pitch can sound like different instruments depending on harmonic content (timbre), with waveform and spectrum visualization.
