Computational models of auditory-nerve responses provide accurate predictions of neural responses to complex sounds in anesthetized animals. In these recordings, the activity of efferent neurons is assumed to be suppressed. The role of efferent control of cochlear gain in neural coding has been further explored in recent models that include inputs to medial olivocochlear efferents from...

Although auditory evoked potentials (AEP) are widely used in clinical settings, the complex relationship between AEP morphology and cochlear status limits their diagnostic specificity. Computational models of AEPs grounded in cochlear mechanics can help link AEP morphology to underlying pathology. However, no validated framework has yet demonstrated this systematically across clinically...

This work investigates cochlear amplification in a transmission line model whose local elements are critical oscillators operating near a Hopf bifurcation. Here, starting from a physically based micromechanical description of the cochlea, the governing equations are reformulated into normal form, allowing the parameters of the reduced model to be directly related to measurable physical...

It has been proposed that a "single strategy" can account for numerous characteristics of the active ear [e.g., spontaneous otoacoustic emission (SOAE), frequency-specific amplification/compression]. The basic heuristic employed essentially amounts to an individual nonlinear oscillator, describable by a single ordinary differential equation, that has the propensity to exhibit a limit cycle...

When asked to discriminate between two stimuli that differ along some dimension, such as intensity, frequency, or orientation, humans exhibit a smallest stimulus difference, or threshold, below which discrimination becomes impossible. These limits on perceptual sensitivity have traditionally been explained by internal noise. Contemporary theories instead link perceptual sensitivity to...

4303. Temporal Modulation Detection in a Model of Auditory Neuropathy Spectrum Disorder (FA2026/297)Paul Mitchell (CeRIAH, Institut Pasteur)08/09/2026, 15:20A14 Physiological Acoustics and Audiology
Auditory Neuropathy Spectrum Disorder (ANSD) is a hearing impairment characterized by abnormal or absent auditory brainstem responses and difficulty understanding speech, especially in noise, while maintaining normal outer hair cell function. Despite this definition, clinical presentation of ANSD is highly variable in practice. Additionally, ANSD has a wide range of underlying pathologies,...

Healthy hearing relies on the careful orchestration and strong coupling of the mechanical, electrical, and fluidic domains in the mammalian cochlea. There is a dearth of data and simulation results for a broad swath of the cochlea including the apex, a region responsible for processing speech frequencies. With the advent of vibrometry based on optical coherence tomography and signal...

Transmission-line models have a unique place in the cochlear-mechanics field. Because they are the simplest model that includes an explicit representation of the traveling waveโs physics, they have been instrumental in developing and popularizing several cochlear mechanical theories that are now well-established (e.g., coherent reflection and amplification theories).Because transmission-line...

Computational cochlear models are essential for auditory research. However, personalization to individual audiological data remains a challenge. While previous work achieved personalization using transient-evoked otoacoustic emissions (TEOAEs), simulating distortion product OAEs (DPOAEs) requires a more explicit bidirectional framework.We introduce TDLM-SNLv3, a fully differentiable model...

The short-time objective intelligibility metric (STOI) [Taal et al., 2011, IEEE Trans. Audio, Speech and Lang. Proc., Vol. 19, No. 7] is a widely used predictor of speech intelligibility and is often applied to evaluate the effects of noise-reduction algorithms and other speech-enhancement strategies. However, STOI is not level sensitive and does not account for the effects of hearing loss,...

Over the past decades, numerous models of the cochlear partition have been proposed to explain key features of cochlear mechanics, including traveling waves, nonlinear amplification, and compressive responses. Among them, the transmission-line model introduced by Geoffrey Zweig and extended by others represents the cochlea as a distributed system of coupled resonant elements interacting...

The auditory brainstem response (ABR) provides a non-invasive measure of synchronous neural activity along the ascending auditory pathway and is widely used in auditory neuroscience. Alterations in the ABR waveform serve as biomarkers of altered neural processing and can provide insight into the mechanisms of auditory disorders, including tinnitus. In this work, we present the first steps...
