Abstract

The present disclosure relates to media players, such as portable electronic devices, vehicle audio systems, home stereo systems, etc. In particular, it relates to the management of the sound pressure level generated by portable electronic devices. A method and system for controlling the consumed audio dose of a user of a media player is described. The method comprises the steps of selecting a first frequency range from the total frequency range relevant for the human ear; of determining the audio dose already consumed by the user within the first frequency range; of evaluating the audio dose of a media track within the first frequency range and the already consumed audio dose of the user within the first frequency range; and of controlling the audio dose generated by the media player based on the evaluating step.

Claims (54)

1. A method for controlling the consumed audio dose of a user of a media player within a first and a second frequency range from the total frequency range relevant for the human ear, the first and the second frequency ranges being different, the method comprising:

determining the audio dose already consumed by the user within the first frequency range;

determining the audio dose within the first frequency range of a set of media tracks;

determining the audio dose already consumed by the user within the second frequency range;

determining the audio dose within the second frequency range of the set of media tracks;

determining, from the audio dose of the set of media tracks within the first frequency range and the already consumed audio dose of the user within the first frequency range, a potentially consumed audio dose for each of the media tracks of the set of media tracks within the first frequency range, wherein determining the potentially consumed audio dose for a media track within the first frequency range comprises

weighting the already consumed audio dose within the first frequency range by a first weight;

weighting the audio dose of the media track within the first frequency range by a second weight; and

determining a first weighted sum of the consumed audio dose and the audio dose of the media track in the first frequency range; wherein the first weighted sum corresponds to the potentially consumed audio dose for the media track within the first frequency range;

determining, from the audio dose of the set of media tracks within the second frequency range and the already consumed audio dose of the user within the second frequency range, a potentially consumed audio dose for each of the media tracks of the set of media tracks within the second frequency range, wherein determining the potentially consumed audio dose for a media track within the second frequency range comprises

weighting the already consumed audio dose within the second frequency range by the first weight;

weighting the audio dose of the media track within the second frequency range by the second weight; and

determining a second weighted sum of the consumed audio dose and the audio dose of the media track in the second frequency range; wherein the second weighted sum corresponds to the potentially consumed audio dose for the media track in the second frequency range; and

selecting a media track from the set of media tracks for play-back on the media player, the selected media track providing a potentially consumed audio dose in the first and the second frequency range and a predetermined value for the second frequency range, respectively.

2. The method of claim 1 , wherein the first frequency range is determined by

splitting the total frequency range into N sub-ranges; wherein N is greater than one; and

selecting one of the N sub-ranges as the first frequency range.

3. The method of claim 2 , wherein the N sub-ranges correspond to the Bark scale.

4. The method of claim 1 , comprising:

determining a playlist for playing back media tracks on the media player by selecting a plurality of media tracks from the set of media tracks wherein the plurality of media tracks provides a potentially consumed audio dose in the first and the second frequency range which does not exceed a pre-determined value for the first frequency range and a pre-determined value for the second frequency range, respectively.

5. The method of claim 1 , further comprising

determining the first and second weighted sum for a plurality of media tracks.

6. The method of claim 1 , further comprising

updating the audio dose consumed by the user in the first and second frequency range, the updating being based on a separate leaky integration of the previously consumed audio dose and the audio dose of the selected media track in the first and second frequency range.

7. The method of claim 1 , wherein determining the consumed audio dose comprises

weighting the consumed audio dose with a weight associated with the time instance at which the audio dose was consumed; wherein the weight decreases with increasing anteriority of the consumed audio dose.

8. The method of claim 1 , wherein determining the audio dose of a media track within a frequency range comprises:

weighting the audio dose of the set of media tracks within the frequency range using weights associated with human auditory perception.

9. The method of claim 1 , wherein determining the audio dose of a media track comprises:

extracting a plurality of segments of the media track using a window function;

determining the audio doses for the plurality of segments of the media track; and

determining the audio dose of the media track as the sum of the audio doses of the plurality of segments of the media track.

10. The method of claim 1 , further comprising

selecting a media category,

wherein the selection of a media track is restricted to media tracks from the selected category.

11. An electronic device, comprising

an audio rendering component operable to generate an audio dose to a user;

a memory operable to store a set of media tracks; and

a processor operable to

determine the audio dose already consumed by the user within a first frequency range from the total frequency range relevant for the human ear;

determine the audio dose within the first frequency range of the set of media tracks;

determine the audio dose already consumed by the user within a second frequency range from the total frequency range relevant for the human ear;

the first and the second frequency ranges being different,

determine the audio dose within the second frequency range of the set of media tracks;

determine, from the audio dose of the set of media tracks and the already consumed audio dose of the user within the first frequency range, a potentially consumed audio dose for each of the media tracks of the set of media tracks within the first frequency range, wherein for determining the potentially consumed audio dose for a media track within the first frequency range, the processor is operable to

weight the already consumed audio dose within the first frequency range by a first weight;

weight the audio dose of the media track within the first frequency range by a second weight; and

determine a first weighted sum of the consumed audio dose and the audio dose of the media track in the first frequency range; wherein the first weighted sum corresponds to the potentially consumed audio dose for the media track within the first frequency range;

determine, from the audio dose of the set of media tracks and the already consumed audio dose of the user within the second frequency range, a potentially consumed audio dose for each of the media tracks of the set of media tracks within the second frequency range, wherein for determining the potentially consumed audio dose for a media track within the second frequency range, the processor is operable to

weight the already consumed audio dose within the second frequency range by the first weight;

weight the audio dose of the media track within the second frequency range by the second weight; and

determine a second weighted sum of the consumed audio dose and the audio dose of the media track in the second frequency range; wherein the second weighted sum corresponds to the potentially consumed audio dose for the media track in the second frequency range; and

select a media track from the set of media tracks for play back on the media player, the selected media track providing a potentially consumed audio dose in the first and the second frequency range which does not exceed a pre-determined value for the second frequency range, respectively.

12. A non-transitory storage medium comprising a software program adapted for execution on a processor and for performing the method of claim 1 when carried out on a computing device.
