A sound-selective hearing support system using environment sensor network

A Predictive Sensor Network Using Ant System

The need for a robust predictive sensor communication network inspired this research. There are many critical issues in a communication network with different data rate requirements, limited power and bandwidth. Energy consumption is one of the key issues in a sensor network as energy dissipation occurs during routing, communication and monitoring of the environment. This paper covers the routi...

Validation of a Virtual Sound Environment System for Testing Hearing Aids

Validation of a Virtual Sound Environment System for Hearing Aid Testing

Hearing aid (HA) users typically benefit a lot from their HAs in simple acoustic situations like a one-toone conversation in a quiet room, but they have difficulties following a conversation in challenging listening situations involving multiple talkers, background noise and reverberation [1]. The processing power of HAs has increased dramatically over the last 10 years and advanced signal proc...

Re-photography and Environment Monitoring Using a Social Sensor Network

This paper presents a technology capable of enabling the creation of a diffuse, calibrated vision-sensor network from the wealth of socially generated geo-referenced imagery, freely available on the Internet. Through the implementation of an accurate image registration system, based on image processing, terrain modelling and subsequent correlation, we will demonstrate how images taken by the pu...

Hearing System Model and Sound Quality Estimation

The feasibility of and the necessity for an objective estimate of the psycho physiological perception of sound after compression are discussed. Some possible methods are studied. The preferable method is the consonance method. The essential principles of this method are offered algorithm of human auditory system and musical theory. The method and measurements results are discussed. Key-Words:re...
