Ambient noise sampled by a mobile device from a local environment is used to automatically trigger actions associated with content currently playing on the mobile device. In some implementations, subtitles or closed captions associated with the currently playing content are automatically invoked and displayed on a user interface based on a level of ambient noise. In some implementations, audio associated with the currently playing content is adjusted or muted. Actions can be automatically triggered based on a comparison of the sampled ambient noise, or an audio fingerprint of the sampled ambient noise, with reference data, such as a reference volume level or a reference audio fingerprint. In some implementations, a reference volume level can be learned on the mobile device based on ambient noise samples.

A computerized method adjusts two presented audio signals using an audio player. A first audio signal is received and played through an audio playing unit. When a second audio signal that is inserted to be played is received in time during the playing of the first audio signal, a peak amplitude X of a volume of the first audio signal and a peak amplitude Y of a volume of the second audio signal are extracted. Each of the peak amplitude X and the peak amplitude Y are compared with a predetermined threshold value A. The first audio signal and/or the second audio signal are adjusted according to the comparison, and the first audio signal and/or the second audio signal is outputted to the audio playing unit and played through the audio playing unit according to the adjustment for the first audio signal and/or the second audio signal.

A system for receiving multiple conversations or messages and for playing the multiple conversations or messages with a mobile device and wireless earpieces. The system may determine various presentation parameters based on various characteristics of the received messages and may play the messages such that audio appears at distinguishing locations around the user. The system may change how messages and/or conversations are played in response to recognize a change in the focus of the user based on detected user inputs, such as body movement gestures.

A method for processing audio signals optimizes the listening experience for hearing impaired individuals to feel stigmatized by requiring them to employ special hearing-impaired equipment. A user actuated controller controls a mixture of a preferred audio signal and a remaining audio signal across a range sufficiently wide enough to encompass all individuals. The preferred audio is recorded and maintained separate from all remaining audio and delivered to the listener in a manner that maintains the separateness of the preferred audio and the remaining audio. The user actuated controller includes the capability of automatically maintaining the listener established ratio in the face of changes in the audio signal. The user actuated controller enables the user to specify a range about the ratio in which the audio may vary, which permits the listener to expand the audio across a continuous range to whatever dynamic range his hearing can accommodate. The controller automatically adjusts to changes in incoming audio. The controller can react to relatively slowly moving changes or prevent short bursts of sound in the remaining audio from modifying the signal levels. The combination of the above aspects provides a heretofore not possible listening experience that can accommodate the listening desires of all listeners. The combination of the ability to control the ratio of preferred audio to remaining audio and to specify the dynamic range about the ratio in which the audio may vary, coupled with the ability of the controller to automatically adjust the signal levels in response to sudden changes in incoming audio, provides a powerful user capability that truly optimizes the listening experience for any listener.

A scroll-based volume controller detects a user selection to scroll through a browser window loaded with data comprising at least one display element, wherein an audio element is associated with the display element and wherein the size of the displayable data is larger than the display area of the browser window. The scroll-based volume controller, responsive to detecting the user selection to scroll through the browser window, calculates a change in position of the display element relative to the browser window. The audio element may include an audio file that is downloaded or streamed to the browser. Next, the scroll-based volume controller automatically adjusts a volume of the associated audio element based on the calculated change in position of the display element relative to the browser window, such that the volume of the audio element, associated with said display element, is automatically adjusted as the position of the display element changes relative to the particular browser window when the user scrolls through the data in the browser window, without the user having to separately select to adjust the volume of the audio element using a separate volume control input.

For operation of a hearing aid (1; 11) in accordance with the invention, in addition to the hearing aid (1; 11) itself, no further technical aids such as remote control, magnets etc. have to be worn as well.

In a device equipped with audio output, a range of the audio output level in regular use is set. When an attempt is made to change the setting to a volume level exceeding the range of the audio output level having been set, a request is made for an acknowledgement that the operation is appropriate, and only if a reply is given within a given time, the volume setting is changed. Such a method prevents the audio output from a television set or audio equipment to be increased to a volume level higher than necessary due to an operating error in a volume setting operation.
