In 2016, the stochastic resonance (SR) model was introduced as an alternative account of tinnitus-related neuronal hyperactivity, proposing that internally generated neural noise is adaptively upregulated to restore information transmission after hearing loss. Rather than interpreting increased spontaneous activity as maladaptive, the model reframed it as a functional mechanism that enhances signal detection near sensory thresholds, with tinnitus emerging as a side effect of adaptive sensory optimization. Over the past decade, this framework has evolved from a phenomenological hypothesis into a broader neurocomputational theory linking information theory, adaptive signal detection, multichannel auditory processing, and cross-modal plasticity. Computational modeling, large-scale clinical analyses, and animal experiments have provided converging support for key predictions, including improved detectability under specific noise conditions and frequency-specific phantom percepts. The framework has also inspired a therapeutic approach based on spectrally matched near-threshold noise stimulation and has recently been integrated into a unified account of auditory phantom perception that combines stochastic resonance, central gain, homeostatic plasticity, and predictive coding. This review provides a chronological overview of the development of the stochastic resonance model, summarizes major theoretical and empirical advances, and outlines future directions for mechanistic validation and clinical translation. By redefining tinnitus as a consequence of adaptive sensory computation, the model shifts the conceptual focus from pathological dysfunction toward principles of information optimization in neural systems.
