Sound intensity measurement for impulsive sounds

From Sound to Sounds

This chapter addresses machine audition and natural audition by carefully analyzing the difficulties and roles of audition in real-world conditions. The reason for this focus is my experience with the development of a verbal aggression detection system (van Hengel and Andringa, 2007). This system was first deployed in 2004 and 2005 in the inner city of Groningen (the Netherlands), by the abStract

A note on measurement of sound pressure with intensity probes

Early sound symbolism for vowel sounds

Children and adults consistently match some words (e.g., kiki) to jagged shapes and other words (e.g., bouba) to rounded shapes, providing evidence for non-arbitrary sound-shape mapping. In this study, we investigated the influence of vowels on sound-shape matching in toddlers, using four contrasting pairs of nonsense words differing in vowel sound (/i/ as in feet vs. /o/ as in boat) and four r...

Detection and Recognition of Impulsive Sound Signals Detection and Recognition of Impulsive Sound Signals

This thesis is dedicated to the development of automatic methods for detecting and recognizing wideband impulsive sounds. An extensive database with more than 1000 sound samples has been built. This database is made of 10 diversified sound classes connected with surveillance and security applications: door slams, glass breaks, human screams, explosions, gunshots, dogs barking, low bangs, phone ...
