Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Before discussing exemplary embodiments in more detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart may describe the steps as a sequential process, many of the steps can be performed in parallel, concurrently or simultaneously. In addition, the order of the steps may be rearranged. The process may be terminated when its operations are completed, but may have additional steps not included in the figure. The processes may correspond to methods, functions, procedures, subroutines, and the like.
Fig. 1 is a schematic flow chart of a call volume adjusting method provided in an embodiment of the present invention, where the present embodiment is applicable to a real-time voice call, the method may be executed by a call volume adjusting device, and the device may be implemented by software and may be generally loaded in a mobile terminal. As shown in fig. 1, the method includes:
and step 110, determining the current call volume and the current ambient noise volume in the current call process.
The volume is also called loudness and sound intensity, and refers to the subjective feeling of the human ear on the magnitude of the sound heard, and the objective evaluation scale is the amplitude of the sound, and the unit of the volume is usually decibel (dB).
For example, the mobile terminal in this embodiment may be a mobile phone, the current call volume may be the volume of the call sound received by the handset end, the current call volume may be collected by setting a corresponding sound collection component, such as a microphone, at the handset end, or the current call volume may be determined according to a value of the handset volume key. The current environmental noise is noise in the environment where the mobile terminal is located, for example, an environmental noise signal composed of human voice, car voice, wind voice or echo in the external environment, and a microphone can be arranged at a position far away from the user's voice on the mobile phone to collect noise in the surrounding environment, so that interference of the user's voice is avoided, and the obtained noise data is close to real external environment noise.
And step 120, taking the ratio of the current call volume to the current environment noise volume as the current volume ratio.
Illustratively, the current call volume is used as a numerator, and the current ambient noise volume is used as a denominator, so as to obtain a current volume ratio.
And step 130, comparing the current volume ratio with a preset common volume ratio range, and adjusting the call volume according to the comparison result.
For example, the common volume ratio range may be determined by collecting a record of the user's adjustments to the call volume over historical calls, resulting in a common volume ratio range that meets the user's hearing needs. And if the current volume ratio does not conform to the common volume ratio range, adjusting the current call volume to enable the current volume ratio to belong to the common volume ratio range.
According to the technical scheme, the ratio of the current call volume to the noise volume of the current environment is compared with the range of the ratio of the common volume, and then the current call volume is adjusted according to the comparison result. By adopting the technical scheme, the embodiment can automatically adjust the call volume, reduce the repeated operation of adjusting the volume by a user and improve the call quality.
Optionally, the determining of the common volume ratio range may include: determining at least one corresponding historical call volume and at least one corresponding historical ambient noise volume in at least one historical call process; and determining a common volume ratio range according to the ratio of at least one historical call volume to at least one corresponding historical call volume.
For example, the mobile terminal may record the call volume of the user during the historical call process and the ambient noise volume during the call process, perform statistical analysis according to the recorded historical information, and determine the range of the user's common volume ratio to obtain the common volume ratio range meeting the hearing requirement of the user.
The method can establish the corresponding relation between the call volume and the environment noise volume according to the call volume and the environment noise volume information in the historical call process, for example, establish a one-to-one corresponding list or other forms of corresponding relation between the environment noise volume and the call volume, and determine the call volume under different noise volume conditions in a table look-up mode.
Fig. 2 is a schematic flow chart of another call volume adjusting method provided in the embodiment of the present invention. As shown in fig. 2, the method includes:
and step 210, determining the current call volume and the current environment noise volume in the current call process.
For example, the preset maximum decibel value is a preset noise volume threshold, for example, the noise volume threshold may be set to 44 decibels, and when the current ambient noise volume during the call is greater than 44 decibels, the current call volume is not adjusted. Because the sound volume that human ear can bear has certain scope, in order to prevent causing the damage to the human body, the sound volume that general human ear heard preferably does not exceed 50 decibels. When large noise exists in the environment, the voice volume is still increased, which may damage human ears, and the highest decibel value of the noise is set to avoid the damage to the human ears caused by excessively increasing the voice volume, so that the safety of the user is ensured as much as possible.
Optionally, if the current ambient noise volume is higher than the highest decibel value, the current call volume and the current ambient noise volume are determined again.
For example, when the current ambient noise volume during the call is greater than the preset maximum decibel value, the current call volume is not adjusted, and the previous call volume and the current ambient noise volume are re-detected until the current ambient noise volume is less than the preset maximum decibel value, step 230 is performed.
And step 230, if not, taking the ratio of the current call volume to the current environment noise volume as the current volume ratio.
For example, when the noise in the environment is lower than the preset maximum decibel value, the ratio of the current call volume to the current environment noise volume is calculated and used as the current volume ratio.
And 240, comparing the current volume ratio with a preset common volume ratio range, and adjusting the call volume according to the comparison result.
Optionally, the step 240 may include:
comparing the current volume ratio with a preset common volume ratio range; if the current volume ratio is larger than the maximum value of the common volume ratio range, reducing the call volume to enable the new current volume ratio to belong to the common volume ratio range; and if the current volume ratio is smaller than the minimum value of the common volume ratio range, increasing the call volume so that the new current volume ratio belongs to the common volume ratio range. The automatic adjustment of the call volume is realized, and the call quality is improved.
Because when the environment has large noise, if the call volume is still increased, the human ears may be damaged, the technical scheme provided by the embodiment determines the upper limit of the noise for call adjustment by setting the highest decibel value, thereby avoiding the damage to the human ears caused by excessively increasing the call volume and ensuring the safety of the user as much as possible.
Fig. 3 is a flowchart illustrating another call volume adjusting method according to an embodiment of the present invention. As shown in fig. 3, the method may include:
And step 320, connecting the current call.
For example, a sound detection device, such as a microphone, for detecting the volume of the current environmental noise is disposed at a position far away from the user's utterance, so as to avoid interference of the user's utterance and make the obtained noise data approach the real external environmental noise.
And step 350, taking the ratio of the current call volume to the current environment noise volume as the current volume ratio.
And step 360, determining whether the current volume ratio is in the common volume ratio range, if not, executing step 370, and if so, returning to execute step 330.
And step 370, adjusting the current call volume so that the adjusted current volume ratio belongs to the range of the common volume ratio.
Optionally, if the current volume ratio is greater than the maximum value of the common volume ratio range, reducing the current call volume, and adjusting the current volume ratio to the maximum value of the common volume ratio range; if the current volume ratio is smaller than the minimum value of the common volume ratio range, the current call volume is increased, and the current volume ratio is adjusted to the minimum value of the common volume ratio range, so that repeated operation of adjusting the volume by a user is reduced, the optimal current call volume is provided for the user, and the call quality is improved.
According to the technical scheme provided by the embodiment, the upper limit of the noise for call adjustment is determined by setting the highest decibel value, so that the damage to human ears caused by excessively increasing the call volume is avoided, and the safety of a user is ensured as much as possible. When the current noise volume is lower than the set highest decibel value, the current call volume is automatically adjusted according to the current volume ratio and the common volume ratio range, repeated operation of adjusting the volume by a user is reduced, and the call quality is improved.
