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.

Method and system for estimating environmental noise attenuation

A method for headphone playback of target sound. Some of the bins of a sound file are accessed, wherein the sound file has several bins each bin storing a number of audio sections. Audio sections are selected from the accessed bins, and mixed while cross fading to form a target sound sequence. A headphone speaker is driven with the target sound sequence. Other aspects are also described and claimed.

Method and apparatus for generating target sounds

The present disclosure generally relates to user interfaces and techniques for managing audio exposure using a computer system (e.g., an electronic device). In accordance with some embodiments, the electronic device displays a graphical indication of a noise exposure level over a first period of time with an area of the graphical indication that is colored to represent the noise exposure level, the color of the area transitioning from a first color to a second color when the noise exposure level exceeds a first threshold. In accordance with some embodiments, the electronic device displays noise exposure levels attributable to a first output device type and a second output device type and, in response to selecting a filtering affordance, visually distinguishes a set of noise exposure levels attributable to the second output device type.

User interfaces for managing audio exposure

The present disclosure generally relates to user interfaces and techniques for managing and visualizing sound reduction using a computer system. In accordance with some embodiments, the computer system displays an indication that a second noise level is less than a first sound level when the computer system is using a sound reduction device. In accordance with some embodiments, the computer system displays a representation of a noise level at a plurality of different times that indicates a first noise level when a sound reduction effect was in effect, and that indicates a second noise level when the sound reduction effect was not in effect. In accordance with some embodiments, the computer system displays a representation of a sound reduction level for a first time period and receives an input selling a second time period different from the first time period, and in response to the input, the computer system displays a representation of the sound reduction level for the second time period.

Methods and user interfaces for monitoring sound reduction

A method for controlling target sound playback. A display screen of a control device is configured to display a target sound user setting for controlling target sound playback, wherein the target sound user setting controls a stored target sound level parameter that is stored within memory of the control device. A target sound sequence is generated in accordance with the user setting. A speaker is driven with the target sound sequence. Other aspects are also described and claimed.

Managing target sound playback

A method performed by an audio source device. The method obtains an input audio signal and determines a sound output level of a headset based on the input audio signal, a user volume setting, and a sound output sensitivity of the headset. The method determines whether the sound output level is above a threshold. In response to determining that the sound output level is above the threshold, a scalar gain is applied upon the input audio signal to produce an output audio signal for output by the headset.

Method and system for adaptive volume control

In-ear sound pressure level, SPL, is determined that is caused by output audio being converted into sound by a headset worn by a user. The in-ear SPL is converted into a sound sample having units that are suitable for evaluating sound noise exposure. These operations are repeated to produce a sequence of sound samples during playback. This sequence of sound samples is then written to a secure database. Access to the database is authorized by the user. Other aspects are also described and claimed.

Headset playback acoustic dosimetry

Environmental acoustic dosimetry with water event detection

A method for detecting wind using a microphone and a speaker of an electronic device. The method obtains a microphone signal produced by the microphone. The method obtains a speaker input signal produced by the speaker that is emulating a microphone capturing ambient sound in an environment through the speaker. The method determines a coherence between the microphone signal and the speaker input signal and determines whether the coherence is below a coherence intensity threshold. In response to determining that the coherence is below the coherence intensity threshold, the method determines a presence of wind in the environment.

Speaker emulation of a microphone for wind detection

An audio system has an ambient sound enhancement function, in which an against-the-ear audio device having a speaker converts a digitally processed version of an input audio signal into sound. The audio system also has an acoustic noise cancellation (ANC) function that may be combined in various ways with the sound enhancement function, and that may be responsive to voice activity detection. Other aspects are also described and claimed.

Ambient sound enhancement and acoustic noise cancellation based on context

A digital signal processing method for ambient sound acoustic dosimetry. Strength of a microphone signal generated by a watch worn by a user is determined and converted into a sound sample having units for sound noise exposure. This is repeated multiple times to produce a time sequence of sound samples that is written to a secure database access to which is authorized by the user. Other aspects are also described and claimed.

Environmental and aggregate acoustic dosimetry

An audio system has an ambient sound enhancement function, in which an against-the-ear audio device having a speaker converts a digitally processed version of an input audio signal into sound. The input audio signal may be amplified where the amplification may be in accordance with a stored hearing profile of the user (personalized ambient sound enhancement.) The audio system also has an acoustic noise cancellation (ANC) function that may be combined in various ways with the sound enhancement function, and that may be responsive to voice activity detection. Other aspects are also described and claimed.
