This invention discloses a method, device, equipment, and program product for adaptive adjustment of vehicle warning volume, including: acquiring the current vehicle status, current driving scenario, current ambient noise level, and the status of road users outside the target vehicle; determining the current warning type based on the current vehicle status, and determining the corresponding warning volume range based on the current warning type; constructing a multi-objective decision model with the optimization objectives of maximizing warning recognition probability and minimizing auditory discomfort probability, and determining the optimal warning volume value within the warning volume range based on the multi-objective decision model; and adjusting the current warning volume of the target vehicle according to the optimal warning volume value. This invention achieves precise adaptation of warning volume to the vehicle's surrounding environment, taking into account both the recognizability of the warning sound and the auditory experience of other road users, improving the accuracy of vehicle warning volume adjustment, ensuring road traffic safety, and can be applied to the field of vehicle control technology.

This invention relates to the field of hearing aids, specifically to a sound processing method for an air conduction hearing aid. The method includes a receiving module, an analysis module, a processing module, and a playback module. The receiving module receives sound waves from the external environment, converting all received sound waves into electrical signals. These converted electrical signals are sent to the analysis module in real time for analysis. The analysis identifies noise signals within the electrical signals and analyzes the magnitude of signal fluctuations. The processing module selects a corresponding amplification factor based on the amplitude of the sound waves. Different sound wave amplitudes require different amplification factors. When the wearer is in a noisy environment, the amplitude of sound waves in the surrounding environment is greater than in a quiet environment. By associating different sound wave amplitudes with different amplification factors, the hearing aid can adjust the volume of the played sound according to the ambient noise level, preventing the wearer's ears from being constantly under high load.

Devices, systems, and methods are disclosed for customizing audio experiences associated with operation of a ridable device. An electronic device having a processor detects contextual information such as speed, acceleration, ambient noise level, environment type, or location of the ridable device. Sensor data from accelerometers, gyroscopes, microphones, cameras, or positioning systems may be processed to identify these conditions. Based on the detected context, the electronic device determines audio configuration parameters, including selection of audio content, adjustment of volume, blending of tracks, or modification of tempo or pitch. The determined parameters are applied to output audio through one or more speakers of the electronic device, the ridable device, or associated accessories. In some implementations, playback is synchronized with other riders using a common time reference, geo-fence triggers are employed to provide location-specific content, or warning sounds are generated when nearby objects are detected, enhancing both rider enjoyment and environmental awareness.

The present application relates to the technical field of signal processing, and particularly relates to a noise elimination method, device, equipment and computer readable storage medium, the method comprising: obtaining an ambient sound signal of an external environment in which an audio device is located, and determining an ambient noise level of the ambient sound signal; obtaining an input audio signal of the audio device, and determining a base gain of a noise elimination filter of the audio device based on the input audio signal; adjusting the base gain based on the ambient noise level to obtain a filter gain, wherein the filter gain and the ambient noise level are in a negative correlation relationship; and processing the input audio signal of the audio device through the filter gain to eliminate noise when the input audio signal is played. The present application makes the noise elimination method adapt to different ambient noises, so that the noise elimination method can meet the needs of different ambient noises, thereby improving the practicability of the noise elimination method.

This application provides a call method, an electronic device method, and a computer storage medium. The electronic device can detect the ambient noise level and whether anyone is nearby. When the electronic device is in a quiet environment and a person is detected, it can adjust the amplitude of the call data to reduce the leakage noise of the call audio corresponding to the call data played through the receiver. Alternatively, the electronic device can play a covert sound signal corresponding to the call audio played through the receiver to cancel out the leakage data and prevent people near the electronic device from accessing the private content of the call audio. This method improves the anti-leakage effect and enhances the user's call experience.

This application provides an audio playback method, electronic device, and vehicle, relating to the field of smart cockpit technology. In response to concurrent playback requests for multiple types of audio within the cockpit, the target playback volume for each type of audio is dynamically determined based on the ambient noise level within the cockpit. This can counteract the obscuring effect of ambient noise on key information by increasing the signal-to-noise ratio of the played audio relative to ambient noise when multiple types of audio are mixed and played, thus overcoming the limitation of simply linearly superimposing multiple types of audio, which results in important information being buried. Furthermore, mixing and playing multiple types of audio based on the target playback volume intelligently highlights important audio containing substantial content and reasonably suppresses secondary audio. The dynamic adjustment of the target playback volume of each type of audio in the mixed playback based on the ambient noise level in this solution ensures that users can still clearly obtain important information in noisy environments, significantly improving the auditory experience within the cockpit.
