Problems solved by technology

Both of these methods will affect the normal call quality: lowering the voice or radio interference will make it difficult for the caller to distinguish your voice from the noisy background noise, especially when the call is made at a high radio volume. disgust

Embodiment Construction

[0066] The present invention can adopt a computer with multimedia function (promptly comprise microphone device, the sound card that can sample and output), the sound that is disturbed is converted into the MIC port of electric signal incoming sound card by microphone, and sound card samples it as corresponding The digital signal is streamed and stored in computer memory. After the digital signal is analyzed and processed by the CPU of the computer, the interference signal is obtained and output through the AUDIO port of the sound card. After being amplified by the speaker, the interference signal is transformed into a sound signal and the interfered sound is superimposed on each other in the space and finally achieves the interference effect.

[0067] The advantage is that it is completely realized by computer software and does not require additional investment. But at the same time, there is a relatively high requirement for the computing power of the computer, that is, a co...

Abstract

The invention relates to a voice interference method, which comprises the flowing steps: firstly, interfered voice signal acquiring; secondly, voice signal processing; thirdly, interfering signal output. The first step also comprises the steps of interfered voice signal acquiring, converting acquired signals into electrical signals, and converting electrical signals into digital signals; the second step also comprises the steps of obtaining digital signals through the first step, and producing interfering signals; the third step also comprises the steps of converting interfering signals into corresponding electrical signals, further amplifying electrical signals and outputting interfering sound, and mutually superposing interfering sound and interfered voice in space to realize the final interference effect. The method has the advantages that the pertinency of interference is high, the output interfering sound is mild, the noise pollution to the surrounding environment is small, and the normal communication among others is not influenced. The voice interference method can be applied to the voice interference in an enclosed space or the voice signal interference in an open space.

Description

technical field [0001] The invention belongs to the field of acoustics, and in particular relates to a voice interference method. Background technique [0002] The vibration of the sound source body will cause the surrounding air to oscillate, and that oscillation mode is the sound wave. Sound wave is a special mechanical wave transmitted in the air, and its propagation characteristics meet all the laws of wave propagation, that is, interference, diffraction and other phenomena will occur during the propagation process. Sound waves spread in all directions with the help of air, and in the air in an open space, the way of propagation is like gradually blowing soap bubbles, which is a spherical front wave. Sound waves transmitted to the human ear cause the vibration of the eardrum to be received by humans, which is called sound; human language carries certain information in the sound through the strength of the sound, the combination of intonation changes, etc., which is call...
