Method and system for estimating environmental noise attenuation
A method that includes determining a level of sound within an acoustic environment captured by a microphone; receiving, from a headset worn by a user, data indicating an audio processing mode in which the headset is operating; determining a level of attenuation of the sound based on the audio processing mode and the level of sound; estimating sound exposure based on at least the level of attenuation and the level of sound; and transmitting the sound exposure to an application program.
1 . A method performed by at least one programmed processor of an electronic device, the method comprising:
determining a level of ambient sound within an acoustic environment using a microphone signal captured by a microphone of the electronic device;
receiving, from a headset worn by a user, data indicating an audio processing mode in which the headset is operating and one or more device characteristics of the headset;
using the data, the one or more device characteristics, and the level of ambient sound to determine a level of attenuation for the ambient sound at an ear of the user caused by the headset that is worn by the user;
estimating sound exposure based on at least the level of attenuation and the level of ambient sound; and
transmitting the sound exposure to an application program.
2 . The method of claim 1 , wherein the application program is being executed by the electronic device that is communicatively coupled with the headset, the application program configured to display a notification based on the sound exposure on a display of the electronic device.
3 . The method of claim 2 , wherein the notification comprises an in-ear sound pressure level (SPL) value.
4 . The method of claim 1 , wherein the electronic device is a wearable device that is being worn by the user while the headset is worn on a head of the user.
5 . The method of claim 1 , wherein the audio processing mode is an active noise cancellation (ANC) mode in which one or more speakers of the headset is producing anti-noise, wherein the level of attenuation is based on an indication that the ANC mode is being performed by the headset.
6 . The method of claim 1 , wherein the audio processing mode is a pass-through mode in which the headset passes through a sound from within the acoustic environment using one or more speakers, wherein the level of attenuation is based on an indication that the pass-through mode is being performed by the headset.
7 . The method of claim 1 ,
wherein the level of attenuation is determined in response to determining that the headset is in wireless communication with the electronic device and in response to determining that the headset is operating in the audio processing mode based on the received data,
wherein transmitting the sound exposure comprises transmitting, over a wireless communication link, the sound exposure to the electronic device on which the application program is being executed.
8 . The method of claim 1 , wherein the level of ambient sound is a first level of ambient sound, and the level of attenuation is a first level of attenuation, wherein the method further comprises:
determining a second level of ambient sound within the acoustic environment captured by the microphone; and
using the data indicating the audio processing mode, the one or more device characteristics, and the second level of ambient sound to determine a second level of attenuation, wherein the second level of attenuation is different than the first level of attenuation.
9 . An electronic device comprising:
a microphone;
at least one processor; and
memory having instructions stored therein which when executed by the at least one processor causes the electronic device to:
determine a level of ambient sound within an acoustic environment using a microphone signal captured by the microphone;
receive, from a headset worn by a user, data indicating an audio processing mode in which the headset is operating and one or more device characteristics of the headset;
use the data, the one or more device characteristics, and the level of ambient sound to determine a level of attenuation for the ambient sound at an ear of the user caused by the headset that is worn by the user;
estimate sound exposure based on at least the level of attenuation and the level of ambient sound; and
transmit the sound exposure to an application program.
10 . The electronic device of claim 9 , wherein the application program is being executed by the electronic device that is communicatively coupled with the headset, the application program configured to display a notification based on the sound exposure on a display of the electronic device.
11 . The electronic device of claim 10 , wherein the notification comprises an in-ear sound pressure level (SPL) value.
12 . The electronic device of claim 9 , wherein the electronic device is a wearable device that is being worn by the user while the headset is worn on a head of the user.
13 . The electronic device of claim 9 , wherein the audio processing mode is an active noise cancellation (ANC) mode in which one or more speakers of the headset is producing anti-noise, wherein the level of attenuation is based on an indication that the ANC mode is being performed by the headset.
14 . The electronic device of claim 9 , wherein the audio processing mode is a pass-through mode in which the headset passes through a sound from within the acoustic environment using one or more speakers, wherein the level of attenuation is based on an indication that the pass-through mode is being performed by the headset.
15 . A non-transitory machine-readable medium having instructions stored therein which when executed by at least one processor of an electronic device causes the electronic device to:
determine a level of ambient sound within an acoustic environment using a microphone signal captured by a microphone of the electronic device;
receive, from a headset worn by a user, data indicating an audio processing mode in which the headset is operating and one or more device characteristics of the headset;
use the data, the one or more device characteristics, and the level of ambient sound to determine a level of attenuation for the ambient sound at an ear of the user caused by the headset that is worn by the user;
estimate sound exposure based on at least the level of attenuation and the level of ambient sound; and
transmit the sound exposure to an application program.
16 . The non-transitory machine-readable medium of claim 15 , wherein the application program is being executed by the electronic device that is communicatively coupled with the headset, the application program configured to display a notification based on the sound exposure on a display of the electronic device.
17 . The non-transitory machine-readable medium of claim 16 , wherein the notification comprises an in-ear sound pressure level (SPL) value.
18 . The non-transitory machine-readable medium of claim 15 , wherein the electronic device is a wearable device that is being worn by the user while the headset is worn on a head of the user.
19 . The non-transitory machine-readable medium of claim 15 , wherein the audio processing mode is an active noise cancellation (ANC) mode in which one or more speakers of the headset is producing anti-noise, wherein the level of attenuation is based on an indication that the ANC mode is being performed by the headset.
