Headset sound leakage mitigation
An audio system for a headset includes a plurality of speakers and an audio controller. The plurality of speakers may be in a dipole configuration that cancel sound leakage into a local area of the headset. The controller filters audio content presented by the plurality of speakers to further mitigate leakage of audio content into the local area. The audio determines sound filters based on environmental conditions, such as ambient noise levels, as well as based on the audio content being presented.
1. A method comprising:
determining, by a headset, a sound filter based in part on an environmental condition and a sound leakage attenuation level for an audio frequency; and
applying the sound filter to audio content for presentation by a dipole speaker on the headset, such that the audio content at the audio frequency is attenuated by at least the sound leakage attenuation level.
2. The method of claim 1 , further comprising receiving the environmental condition from an external system.
3. The method of claim 1 , wherein the environmental condition comprises a location of a person.
4. The method of claim 1 , further comprising classifying a type of the audio content.
5. The method of claim 4 , wherein the sound filter is determined based in part on the type of the audio content.
6. The method of claim 1 , wherein the sound filter comprises a low pass filter.
7. The method of claim 1 , wherein the sound leakage attenuation level is based on an ambient noise level.
8. A headset comprising:
a dipole speaker; and
an audio controller configured to:
determine a sound filter based on an environmental condition, wherein the environmental condition comprises a location of a person; and
mitigate sound leakage by applying the sound filter to audio content provided to the dipole speaker based on a privacy setting.
9. The headset of claim 8 , wherein the audio controller is configured to receive the environmental condition from an external system.
10. The headset of claim 8 , wherein the audio controller is further configured to select, based on the environmental condition, a sound leakage attenuation level for a frequency band.
11. The headset of claim 8 , wherein the audio controller is further configured to classify a type of the audio content.
12. The headset of claim 11 , wherein the sound filter is determined based in part on the type of the audio content.
13. The headset of claim 8 , wherein the sound filter comprises a low pass filter.
14. The headset of claim 8 , wherein the environmental condition further comprises an ambient noise level.
15. A method comprising:
selecting, based on an environmental condition, a sound leakage attenuation level for a frequency band; and
applying, based on the sound leakage attenuation level for the frequency band, a sound filter to audio content for presentation by a transducer array on a headset.
16. The method of claim 15 , further comprising receiving the environmental condition from an external system.
17. The method of claim 15 , wherein the environmental condition comprises a location of a person.
18. The method of claim 15 , further comprising classifying a type of the audio content.
19. The method of claim 18 , wherein the sound filter is determined based in part on the type of the audio content.
20. The method of claim 15 , wherein the transducer array comprises a dipole speaker.
