“…For this purpose, we used a well‐established and widely used model of the auditory periphery (Bruce et al., 2018). This model provides a phenomenological description of the major functional stages of the auditory periphery, from the middle ear up to the auditory nerve (Osses et al., 2022). The implementation used in the present study is available as the routine ‘bruce2018’ within the AMT toolbox (v.1.0) for MATLAB (Majdak et al., 2022).…”

In quiet, envelope tracking in the low amplitude modulation range (<20 Hz) is correlated with the neuronal discrimination between communication sounds as quantified by mutual information from the cochlear nucleus up to the auditory cortex.* At each level of the auditory system, auditory neurons keep their abilities to track the communication sound envelopes in situations of acoustic degradation such as vocoding and the addition of masking noises up to a signal-to-noise ratio of -10 dB. * In noise, the increase in between-stimulus envelope similarity explains both the reduction in behavioral and neuronal discrimination in the auditory system. * Envelope tracking can be viewed as a universal mechanism allowing neural and behavioral discrimination as long as the temporal envelope of communication sounds display some differences.

“…To simulate EFR responses, we used the Verhulst et al model (version 1.2) of the auditory periphery (Vecchi & Verhulst, 2019;Verhulst et al, 2018) whose EFR output has been previously compared with responses recorded in human subjects (Vasilkov et al, 2021;Verhulst et al, 2018). Combining a bandpass filter in the middle ear with an elegant transmission-line model in its inner ear, the Verhulst et al model effectively describes many facets of human cochlear mechanics including its frequency and intensity sensitivities (Vecchi et al, 2022;Vecchi & Verhulst, 2019;Verhulst et al, 2018). Subsequent transduction and propagation of this signal along parallel frequency channels in the auditory periphery are achieved using biophysically realistic processes, leading to its broad capture of physiological behaviour in the auditory nerve (AN), cochlear nucleus (CN), and inferior colliculus (IC) at both a single-unit and population level.…”

Differences between children and adults in the neural encoding of voice fundamental frequency in the presence of noise and reverberation

Environmental noise and reverberation challenge speech understanding more significantly in children than in adults. However, the neural/sensory basis for the difference is poorly understood. We evaluated the impact of noise and reverberation on the neural processing of the fundamental frequency of voice (f 0 )-an important cue to tag or recognize a speaker. In a group of 39 6-to 15-year-old children and 26 adults with normal hearing, envelope following responses (EFRs) were elicited by a male-spoken /i/ in quiet, noise, reverberation, and both noise and reverberation. Due to increased resolvability of harmonics at lower than higher vowel formants that may affect susceptibility to noise and/or reverberation, the /i/ was modified to elicit two EFRs: one initiated by the low frequency first formant (F1) and the other initiated by mid to high frequency second and higher formants (F2+) with predominantly resolved and unresolved harmonics, respectively. F1 EFRs were more susceptible to noise whereas F2+ EFRs were more susceptible to reverberation. Reverberation resulted in greater attenuation of F1 EFRs in adults than children, and greater attenuation of F2+ EFRs in older than younger children. Reduced modulation depth caused by reverberation and noise explained changes in F2-+ EFRs but was not the primary determinant for F1 EFRs. Experimental data paralleled modelled EFRs, especially for F1. Together, data suggest that noise or reverberation influences the robustness of f 0 encoding depending on the resolvability of vowel harmonics and that maturation of processing temporal/ envelope information of voice is delayed in reverberation, particularly for low frequency stimuli.

“…Auditory models (or model suites) have been developed to approximate auditory transduction (Osses et al 2022). They serve two purposes: to embody knowledge accrued about the peripheral auditory system (and test it), and to generate patterns of auditorynerve discharge for simulation of downstream processes within the brainstem.…”

Simple and efficient auditory-nerve spike generation

This brief paper documents a simple and efficient method to generate auditory-nerve spike trains for the purpose of simulating neural processes of auditory perception. In response to sound, each auditory nerve fiber carries information to the auditory brainstem in the form of a train of spikes (action potentials), the timing and rate of which reflect the sound. The generation process is usually approximated as Poisson process with a time-varying rate, further modified by refractory effects. The purpose, here, is to simulate spike generation as a time- and interval-dependent thinning process applied to a homogenous Poisson process, allowing for fast generation, cheap storage, and unlimited temporal resolution.
