Modeling auditory processing of amplitude modulation
In this thesis a new modeling approach is developed which is able to predict human performance in a variety of experimental conditions related to modulation detection and modulation masking. Envelope uctuations are analyzed with a modulation lterbank. The parameters of the lterbank were adjusted to allow the model to account for modulation detection and modulation masking data with narrowband c...
متن کاملModeling auditory processing of amplitude modulation. II. Spectral and temporal integration.
A multi-channel model, describing the effects of spectral and temporal integration in amplitude-modulation detection for a stochastic noise carrier, is proposed and validated. The model is based on the modulation filterbank concept which was established in the accompanying paper [Dau et al., J. Acoust. Soc. Am. 102, 2892-2905 (1997)] for modulation perception in narrow-band conditions (single-c...
متن کاملModeling auditory processing of amplitude modulation. I. Detection and masking with narrow-band carriers.
This paper presents a quantitative model for describing data from modulation-detection and modulation-masking experiments, which extends the model of the "effective" signal processing of the auditory system described in Dau et al. [J. Acoust. Soc. Am. 99, 3615-3622 (1996)]. The new element in the present model is a modulation filterbank, which exhibits two domains with different scaling. In the...
متن کاملEvidence of functional connectivity between auditory cortical areas revealed by amplitude modulation sound processing.
The human auditory cortex includes several interconnected areas. A better understanding of the mechanisms involved in auditory cortical functions requires a detailed knowledge of neuronal connectivity between functional cortical regions. In human, it is difficult to track in vivo neuronal connectivity. We investigated the interarea connection in vivo in the auditory cortex using a method of dir...
متن کاملBilateral Collicular Interaction: Modulation of Auditory Signal Processing in Amplitude Domain
In the ascending auditory pathway, the inferior colliculus (IC) receives and integrates excitatory and inhibitory inputs from many lower auditory nuclei, intrinsic projections within the IC, contralateral IC through the commissure of the IC and from the auditory cortex. All these connections make the IC a major center for subcortical temporal and spectral integration of auditory information. In...
