摘要： The present disclosure provides systems and method for determining a background noise level. The device may receive audio from two or more microphones. The audio may include a first signal and a second signal, such that each microphone receives its own signal. The time, loudness, frequency of the first and second signals may be compared to determine the source of the audio, such as whether the audio is the user's voice or background noise. Based on the source of the audio, the audio may be suppressed to reduce false estimations when calculating the background noise level.

摘要： The present disclosure provides systems and method for adjusting the audio output of a wearable device based on an audio gain profile of a user. The wearable device may receive an audiogram indicating one or more frequency ranges associated with hearing loss. The wearable device may determine the audio gain profile based on the audiogram. The wearable device may use one or more adjustment modules to determine a gain to apply to the audio output based on the audio gain profile. The adjustment modules may include an active noise control module, a hearing assistance module, and a transparency control module. The wearable device may determine the amount of gain to apply using a least mean square algorithm and/or a machine learning model.

摘要： Methods, systems, and devices for enhanced digital headsets are disclosed. An enhanced USB-C headset includes a USB-C connector, a cable extending from the USB-C connector, an inline control box coupled to the USB-C connector through the cable, and a first earphone and a second earphone. The cable includes conductors for transmitting DC bus power, power return, and differential digital signals and extends at least one foot in length. The control box includes a single circuit board, with circuitry for managing digital communications, converting audio data, and providing output signals to drive analog speaker elements of the earphones.

摘要： Exemplary wearable computing systems may include a head-mounted display that is configured to provide indirect bone-conduction audio. For example, an exemplary head-mounted display may include at least one vibration transducer that is configured to vibrate at least a portion of the head-mounted display based on the audio signal. The vibration transducer is configured such that when the head-mounted display is worn, the vibration transducer vibrates the head-mounted display without directly vibrating a wearer. However, the head-mounted display structure vibrationally couples to a bone structure of the wearer, such that vibrations from the vibration transducer may be indirectly transferred to the wearer's bone structure.
