Mobile terminal with noise-identification communication-variation function and method of varying the same

Abstract

The present invention discloses a mobile communication terminal with noise-identification communication-variation function and method of varying the same, characterized by comprising parts of: a display part capable of converting received voice signal in to character and outputting the same; a control module automatically measuring and determining surrounding noise of receiver in communication, if noise having noise value higher than set reference, converting received voice signal in to character and outputting the same onto said display part. The invention is different with method of amplifying communication voice of existing art, and has effects that, even surrounding noise exists in communication process, voice of opposite side can be outputted as character message on LCD display screen, such that voice of opposite side can be comprehended indeed and recognized in vision, which achieves continuous and stable communication, and prevents generating damnification in hearing.

Description

technical field [0001] The present invention relates to a mobile communication terminal with the function of changing the calling method by noise recognition and a method for changing the calling method, in particular to a method for changing the call method when the noise around the called person is detected by the noise measuring device carried by the terminal is higher than the predetermined reference noise value, A mobile communication terminal and a method for changing a call method having a function of changing a call method by noise recognition, which convert the other party's voice signal into a text message and output it to a display screen. Background technique [0002] Generally speaking, sound is perceived when changes in air pressure are applied to a person's eardrum. The minimum sound pressure that can be perceived as sound is 2TIMES 10^{-5}N / m^{2}. Therefore, the magnitude of the sound heard is proportional to the magnitude of the sound pressure. Human being...

Problems solved by technology

Around 40dB will have an impact on the human body. If it reaches 70dB, the peripheral blood vessels of the person will contract. When the average surrounding noise reaches 80dB or more, it will directly affect the hearing of the person. It is difficult to recognize the voice of the other party when talking on the phone.

[0003] In the past, when there was noise around, the person who answered the call had to find a quiet place where the noise could not be heard or wait for the noise to disappear before resuming the phone call, which was very inconvenient

In the prior art, when there is noise around the caller, the answering sound of the mobile communication terminal can also be raised to make a call, but when the answering sound is higher than the surrounding noise, as mentioned above, when it reaches more than 70dB, It has adverse effects on the caller's hearing and may cause hearing loss. Therefore, there are certain limitations in amplifying the answering sound according to the surrounding noise.
