In one exemplary embodiment, a computer-implemented method includes the step of determining an age group of a first user. Media content available to the first user is identified. It is determined whether the user has permission to listen to the media content. The media content is jammed with a sound wave at a frequency that can be heard by the user when the user does not have permission to listen to the media content. Optionally, a voice age-recognition algorithm to determine the age group of the first user. An age-group of a second user can be determined. The first user and the second user may be proximate to a media player providing the ambient sound stream.
