Learning auditory space : generalization and long-term effects

Background: Previous findings have shown that humans can learn to localize with altered auditory space cues. Here we analyze such learning processes and their effects up to one month on both localization accuracy and sound externalization. Subjects were trained and retested, focusing on the effects of stimulus type in learning, stimulus type in localization, stimulus position, previous experience, externalizati...

Real-time auralisation system for virtual microphone positioning

A computer application was developed to simulate the process of microphone positioning in sound recording applications. A dense, regular grid of impulse responses pre-recorded on the region of the room under study allowed the sound captured by a virtual mi- crophone to be auralised through real-time convolution with an anechoic stream representing the sound source. Convolution was performed using a block-based ...

On the improvement of localization accuracy with nonindividualized HRTF-based s...

Auralization is a powerful tool to increase the realism and sense of immersion in Virtual Reality environments. The Head Related Transfer Function (HRTF) filters commonly used for auralization are non-individualized, as obtaining individualized HRTFs poses very serious practical difficulties. It is therefore extremely important to understand to what extent this hinders sound perception. In this paper, we add...

Emissões otoacústicas em pacientes com zumbido incômodo e audição normal

Algoritmos genéticos e computação paralela para problemas de roteirização de ve...

O presente trabalho propõe a utilização de metaheurísticas e computação paralela para a resolução de um problema real de roteirização de veículos com frota heterogênea, janelas de tempo e entregas fracionadas, no qual a demanda dos clientes pode ser maior que a capacidade dos veículos. O problema consiste na determinação de um conjunto de rotas econômicas que devem atender à necessidade de cada cliente respeita...
