Audio adjustment system and method

Abstract

An audio adjustment method, wherein an input audio is output into an output audio according to an audio control parameter, and the output audio has an output audio level, and the audio adjustment method includes the steps of: determining an environmental noise level; calculating the environmental noise level level and the ratio of the output audio level to obtain a measurement value; the measurement value is compared with a predetermined threshold value, wherein the predetermined threshold value is a sound comfort value; and according to the measurement value and The comparison result of the predetermined threshold determines whether to adjust the audio control parameter, and if so, adjusts the audio control parameter, and outputs the output audio according to the adjusted audio control parameter. The audio adjustment method can adjust the output audio according to the needs of different users in different environments.

Description

[0001] 【Technical field】 [0002] The present invention relates to an audio adjustment system and method, in particular to an audio adjustment system and method capable of dynamically adjusting output audio. [0003] 【Background technique】 [0004] Nowadays, general audio-visual playback devices such as TVs or flat-panel monitors have become one of the indispensable tools for modern leisure and entertainment. For example, combining the functions of TVs and flat-panel displays allows the audio-visual playback device to watch TV channels and also be used as a computer screen. use. With the development of various display components and image processing technologies, audio-visual playback devices can achieve near-real images and sounds. However, whether the volume intensity is appropriate is a very important key factor for the user's overall audio-visual experience.

Problems solved by technology

[0005] Due to the influence of external environmental noise, the user may be forced to frequently adjust the output volume of the audio-visual playback device. For example, when the external environment is noisy, the user needs to manually increase the output volume in order to make the hearing clear. On the contrary, when the external environment noise becomes small, the user needs to manually reduce the intensity of the output volume, and the change of the output volume intensity must be able to meet the user's demand for volume suitability

In the case of frequent changes in environmental noise, users need to manually adjust the output volume level, which increases the inconvenience of viewing

At present, although some multimedia systems are designed to automatically adjust the output audio intensity according to the environmental noise, they cannot change the output volume intensity in response to the personal preferences of different users and different noise environments, so it is often impossible to achieve efficient Volume adjustment and meeting the user's needs for volume suitability, or the system design is too complicated, which makes it inconvenient for the user to operate and its manufacturing cost is also high
