Periphear : a nonlinear active model of the auditory periphery
نویسندگان
چکیده
This paper describes a phenomenological model of the auditory periphery which consists of a bank of nonlinear time-varying parallel lters. Realistic lter shapes are obtained with the all-pole gammatone lter (APGF) which provides both a good approximation of the far more complex wave-propagation or cochlear mechanics models and a very simple implementation. The model also includes an active, distributed feedback that controls the damping parameter of the APGF. As a result, the model reproduces several observed phenomena including compression, two-tone suppression and suppression of tones by noise.

متن کاملA New Nonlinear Multi-objective Redundancy Allocation Model with the Choice of Redundancy Strategy Solved by the Compromise Programming Approach
One of the primary concerns in any system design problem is to prepare a highly reliable system with minimum cost. One way to increase the reliability of systems is to use redundancy in different forms such as active or standby. In this paper, a new nonlinear multi- objective integer programming model with the choice of redundancy strategy and component type is developed where standby strategy ...
متن کاملProsthetic Avian Vocal Organ Controlled by a Freely Behaving Bird Based on a Low Dimensional Model of the Biomechanical Periphery
Because of the parallels found with human language production and acquisition, birdsong is an ideal animal model to study general mechanisms underlying complex, learned motor behavior. The rich and diverse vocalizations of songbirds emerge as a result of the interaction between a pattern generator in the brain and a highly nontrivial nonlinear periphery. Much of the complexity of this vocal beh...
