TL;DR: Music exposure has made music exposure the most studied source of excessive sound exposure to children and youths in several countries, and not all evidence available confirms increased risk with increasing exposures, and the possibility of a toughening protective effect of such exposures has been suggested.
Abstract: In the past two decades, the number of publications on the risk of acquired hearing loss among children and young adults has increased substantially. The introduction of MP3 players and a lawsuit t...

TL;DR: In this article, a system and method for locating program boundaries and commercial boundaries using audio categories is described. But the system is not suitable for use in a video signal processor, as it requires the use of an audio classifier controller that determines the rates of change of audio categories.
Abstract: For use in a video signal processor, there is disclosed a system and method for locating program boundaries and commercial boundaries using audio categories. The system comprises an audio classifier controller that obtains information concerning the audio categories of the segments of an audio signal. Audio categories include such categories as silence, music, noise and speech. The audio classifier controller determines the rates of change of the audio categories. The audio classifier controller then compares each rate of change of the audio categories with a threshold value to locate the boundaries of the programs and commercials. The audio classifier controller is also capable of classifying at least one feature of an audio category change rate using a multifeature classifier to locate the boundaries of the programs and commercials.

TL;DR: In this article, an arrangement and method for controlling audio reception by occupants of a vehicle in which the position of any occupants is determined and the entertainment system controlled to provide specific sound for the occupants based on the determined positions of the occupants.
Abstract: Arrangement and method for controlling audio reception by occupants of a vehicle in which the position of any occupants is determined and the entertainment system controlled to provide specific sound for the occupants based on the determined positions of the occupants. Sound generating components of the entertainment system are automatically adjustable based on the determined position of the occupants. A hypersonic sound generating system may be used wherein ultrasonic frequency generators generate ultrasonic waves which mix with ultrasonic waves generated by another ultrasonic frequency generator to thereby cause the creation of new audio frequencies in an area determined based on the position of the occupants. In addition, the presence and direction of unwanted noise may be detected and sound created to cancel the unwanted noise in the area including the determined positions of any occupants.
