Timbre is a key perceptual feature that allows discrimination between different sounds. Timbral sensations are highly dependent on the temporal evolution of the power spectrum of an audio signal. In order to quantitatively characterize such sensations, the shape of the power spectrum has to be encoded in a way that preserves certain physical and perceptual properties. Therefore, it is common pr...

Numerous archives of entertainment soundtracks and other recordings such as environmental noise samples have imposed a big data challenge in audio related industries. This necessitates the use of machine audition and retrieval tools to extract semantic information for various applications. Speech recognition, environmental noise classification and music information retrieval tools haven been de...

Automatic identification of activities can be used to provide information to caregivers of persons with dementia for identifying assistance needs. Environmental audio provides significant and representative information of the context, making microphones a choice to identify activities automatically. However, in real situations, the audio captured by microphones comes from overlapping sound sour...

Autonomous audio recording is stimulating new field in bioacoustics, with a great promise for conducting cost-effective species surveys. One major current challenge is the lack of reliable classifiers capable of multi-species identification. We present PROTAX-Sound, a statistical framework to perform probabilistic classification of animal sounds. PROTAX-Sound is based on a multinomial regressio...

Due to the wireless transmission capability and ease of replaceability of wireless sensor networks (WSN) nodes, they can be deployed in harsh environments for monitoring environmental changes. However, a sensor network faces the challenge of limited residual energy, particularly in audio sensing where large amounts of data are communicated and drainage of sensor energy is significant. In order ...

Introduction: The growing elderly population calls mental health professionals to take measures concerning the treatment of the elderly mental disorders. Today in developed countries, bibliotherapy is used for the treatment of the most prevalent psychiatric disorders. Therefore, this study aimed to investigate the effects of audio book on the elderly mental health of Retirement Center of Shahid...
