Sound Classification in Hearing Aids Inspired by Auditory Scene Analysis
A sound classification system for the automatic recognition of the acoustic environment in a hearing aid is discussed. The system distinguishes the four sound classes “clean speech,” “speech in noise,” “noise,” and “music.” A number of features that are inspired by auditory scene analysis are extracted from the sound signal. These features describe amplitude modulations, spectral profile, harmo...
متن کاملAutomatic Sound Classification Inspired by Auditory Scene Analysis
A sound classification system for the automatic recognition of the acoustic environment in a hearing instrument is discussed. The system distinguishes the four sound classes ‘clean speech’, ‘speech in noise’, ‘noise’, and ‘music’ and is based on auditory features and hidden Markov models. The employed features describe level fluctuations, the spectral form and harmonicity. Sounds from a large d...
متن کامل“Acoustic Scene Analysis” and Digital Hearing Aids
Digital hearing aids have gained rapidly in popularity in recent years, now comprising over 93% of the US market (figure 1). Interestingly, despite this increase, customer satisfaction, benefit, use, and residual disability have not changed appreciably during the past decade (figure 2). One hearing aid feature, however, that has produced considerable increases in patient satisfaction is the dir...
متن کاملAuditory Perception and Verbal Intelligibility in Children with Cochlear Implant, Hearing Aids and Normal Hearing
Objective: The aim of the present research was to compare the auditory perception and verbal intelligibility in children with cochlear implant, hearing aids and normal hearing. Methods: 60 children aged 5-7 years were divided to three groups and each group contained 20 children. The first and second groups were selected ordinarily from children with cochlear implant and hearing aids by conve...
متن کاملEffect of sound classification by neural networks in the recognition of human hearing
In this paper, we focus on two basic issues: (a) the classification of sound by neural networks based on frequency and sound intensity parameters (b) evaluating the health of different human ears as compared to of those a healthy person. Sound classification by a specific feed forward neural network with two inputs as frequency and sound intensity and two hidden layers is proposed. This process...
