In some implementations, the method comprises: identifying at least one noise present in an environment of a user having a user device, an activity the user is currently engaged in, and a physical or emotional state of the user; determining a target ambient noise to be produced in the environment based at least in part on the identified noise, the activity the user is currently engaged in, and the physical or emotional state of the user; identifying at least one device associated with the user device to be used to produce the target ambient noise; determining sound outputs corresponding to each of the one or more identified devices, wherein a combination of the sound outputs produces an approximation of one or more characteristics of the target ambient noise; and causing the one or more identified devices to produce the determined sound outputs. ## Claims ### Claim 1 A method for noise modification, the method comprising: determining a target noise to be produced by an audio device based on a state of a user and a current ambient sound in proximity to the audio device; causing a sound output to be produced by the audio device that produces an approximation of the target noise; determining an updated state of the user; and causing the sound output produced by the audio device to be changed based on an update to the target noise that is determined from the updated state of the user. ### Claim 2 (depends on 1) The method of claim 1, wherein the current ambient sound in proximity to the audio device is detected using a microphone of the audio device. ### Claim 3 (depends on 1) The method of claim 1, wherein the state of the user is determined using a motion sensor. ### Claim 4 (depends on 1) The method of claim 1, wherein the audio device is selected as a device that produces the sound output that approximates the target noise via a user interface presented on a mobile device associated with the audio device. ### Claim 5 (depends on 1) The method of claim 1, wherein the target noise is determined to change a perception of the current ambient sound when the sound output that approximates the target noise is produced. ### Claim 6 (depends on 5) The method of claim 5, wherein the target noise is determined to reduce a perceived loudness of the current ambient sound. ### Claim 7 A system for noise modification, the system comprising: a hardware processor that: determines a target noise to be produced by an audio device based on a state of a user and a current ambient sound in proximity to the audio device; causes a sound output to be produced by the audio device that produces an approximation of the target noise; determines an updated state of the user; and causes the sound output produced by the audio device to be changed based on an update to the target noise that is determined from the updated state of the user. ### Claim 8 (depends on 7) The system of claim 7, wherein the current ambient sound in proximity to the audio device is detected using a microphone of the audio device. ### Claim 9 (depends on 7) The system of claim 7, wherein the state of the user is determined using a motion sensor. ### Claim 10 (depends on 7) The system of claim 7, wherein the audio device is selected as a device that produces the sound output that approximates the target noise via a user interface presented on a mobile device associated with the audio device. ### Claim 11 (depends on 7) The system of claim 7, wherein the target noise is determined to change a perception of the current ambient sound when the sound output that approximates the target noise is produced. ### Claim 12 (depends on 11) The system of claim 11, wherein the target noise is determined to reduce a perceived loudness of the current ambient sound. ### Claim 13 A non-transitory computer-readable medium containing computer executable instructions that, when executed by a processor, cause the processor to perform a method for noise modification, the method comprising: determining a target noise to be produced by an audio device based on a state of a user and a current ambient sound in proximity to the audio device; causing a sound output to be produced by the audio device that produces an approximation of the target noise; determining an updated state of the user; and causing the sound output produced by the audio device to be changed based on an update to the target noise that is determined from the updated state of the user. ### Claim 14 (depends on 13) The non-transitory computer-readable medium of claim 13, wherein the current ambient sound in proximity to the audio device is detected using a microphone of the audio device. ### Claim 15 (depends on 13) The non-transitory computer-readable medium of claim 13, wherein the state of the user is determined using a motion sensor. ### Claim 16 (depends on 13) The non-transitory computer-readable medium of claim 13, wherein the audio device is selected as a device that produces the sound output that approximates the target noise via a user interface presented on a mobile device associated with the audio device. ### Claim 17 (depends on 13) The non-transitory computer-readable medium of claim 13, wherein the target noise is determined to change a perception of the current ambient sound when the sound output that approximates the target noise is produced. ### Claim 18 (depends on 17) The non-transitory computer-readable medium of claim 17, wherein the target noise is determined to reduce a perceived loudness of the current ambient sound.
