Embodiment Construction
[0011] This section is intended to introduce the reader to various aspects of art that may be related to various aspects of the invention that are described and / or claimed hereinafter. This discussion is considered helpful in providing the reader with background information in order to better understand the various aspects of the invention. Accordingly, it should be understood that these statements are to be read as such, and not as admissions of prior art.
[0012] Exemplary embodiments of the present invention allow a parent or other authorized user of an audio system, such as a vehicle audio system, to set a maximum volume level for playing audio programs. For example, an authorized user can set a maximum volume level for wireless or wired rear headphones. The maximum volume level may be set or determined at a level that minimizes or reduces disturbance to other vehicle occupants. In particular, by setting or determining a maximum volume level, the likelihood of discomfor...

The disclosed embodiments relate to an audio system (100) and an associate method. An exemplary embodiment of the system (100) comprises a user interface (104) that enables adjustment of a volume level of an audio signal being reproduced on at least a portion of the audio system to a desired maximum volume level. The user interface further enabling the desired maximum volume level to be selected as a set maximum volume level. A processor (102) electrically interconnected with the user interface is adapted to limit the volume at which audio programs are reproduced on at least a portion of the audio system to said set maximum volume level. An exemplary method comprises generating an audio signal, adjusting a volume level of the audio signal to a desired maximum volume level in response to a user input, and establishing the desired maximum volume level as a set maximum volume level for audio programs played on at least a portion of the audio system (100).
Description
technical field [0001] The present invention relates primarily to audio systems. In particular, the present invention relates to a system and method for setting a maximum volume level for headphones used in confined spaces such as vehicle interiors. Background technique [0002] Many conventional vehicle audio systems allow one or more rear seat occupants to listen to an audio program, such as music or a movie audio portion, via headphones. Such systems also typically provide the listener with the ability to adjust the volume of the audio signal reproduced by the headphones. Since a vehicle is a relatively small space, if a rear seat occupant, such as a child, listens to an audio program at an increased volume level, other occupants of the vehicle may be disturbed. Furthermore, audio systems may allow volume levels that are loud enough to cause discomfort to the user. Accordingly, it would be desirable to have an audio system and related method that facilitates listening ...
