摘要： An electronic device includes a processor. The processor is configured to examine the sound level of an audio signal obtained from an external object for a preset time; change, if the frequency with which the sound level becomes higher than or equal to a specified level satisfies a preset condition, a reference level, at which the gain value for audio signal amplification is changed in accordance with the amplitude change of the audio signal, for at least one section of the audio signal satisfying the preset condition; and amplify the at least one section of the audio signal according to the changed reference level.

摘要： A system capable of self-adjusting both sound level and spectral content to improve audibility and intelligibility of medical device audible cues. Audible cues are stored as sound files. Ambient noise is detected, and the output of the audible cues is altered based on the ambient noise. Various embodiments include processed sound files that are more robust in noisy environments.

摘要： Systems and methods provide a solution to a common nuisance of loud background noise encountered when watching television, allowing the issue to be solved with little or no user interaction. Systems and methods automatically modulate device volume based on background noise level. The systems and methods record a background level of noise, and if that background level of noise increases, the systems and methods automatically increase the content volume which had been set by the user. Exceptions are made for brief sounds or for viewer conversations.

摘要： An electronic device includes one or more microphones, one or more sensors, and one or more processors operable with the one or more microphones and the one or more sensors. The one or more processors, upon the one or more sensors detecting the electronic device is disposed within a repository container, such as a pocket, apply an audio signal adjustment function to signals received from the one or more microphones, thereby mitigating noise in the signals caused by the repository container.

摘要： The present disclosure provides systems and methods for determining a noise level associated with an autonomous vehicle. The autonomous vehicle can include a passenger compartment configured to house one or more passengers. A method can include positioning one or more microphones at one or more locations in the passenger compartment, collecting first data indicative of a first sound level by the one or more microphones with the autonomous vehicle operating at a first operating condition, implementing an operating condition change for the autonomous vehicle from the first operating condition to a second operating condition, collecting second data indicative of a second sound level by the one or more microphones, and determining a noise level associated with the autonomous vehicle based at least in part on the first data and the second data.

摘要： A method of audio processing receives a sequence of sample values, each corresponding with a location in video or audio content; forms an initially estimated quantile value; and then modifies the estimated value in dependence upon a count of the results of comparisons between sample values within a fixed-length interval of the sequence of samples values and the estimated value to form an estimated quantile of the sequence of sample values. The estimated quantile is used in the measurement or control of loudness.

摘要： Among other things, one or more non-transitory machine-readable media storing instructions are described. The stored instructions are executable by one or more processing devices to perform operations comprising analyzing an effect of noise in a spatial unit on sound in the spatial unit, at least part of the sound being produced by audio signals; selecting an adjustment curve among a group of adjustment curves based on one or more characteristics of the noise; and determining an amount of adjustment to be made to the audio signals based on the analyzed effect and the selected adjustment curve.

摘要： In a communications system for an individual who has access to a vehicle-mounted two-way radio and a portable two-way radio which includes a speakermic having a speaker through which audible messages are transmitted for the individual to hear, there is provided a volume control arrangement associated with the speakermic through which the audio volume of the speakermic speaker can be adjusted. The system also includes a transmitter for transmitting a signal to the volume control arrangement that the individual is seated in the vehicle, and further includes a transmitter for transmitting a signal to the volume control arrangement that the mobile radio is energized. A receiver is associated with the volume control arrangement of the speakermic so that upon receipt of the signals transmitted from the two transmitters, the audio volume of the speaker of the speakermic is automatically lowered.
