step 60, when the analog interference voice type is judged not to be the mute voice interference, judging whether the analog interference voice type is the current voice interference;
step 70, when the type of the simulated interference voice is judged to be the current voice interference, determining a first attenuation factor according to the current interference level;
step 80, generating corresponding current voice interference information according to the voice data, the current interference level and the first attenuation factor of any frame in any voice packet to be interfered; wherein the step 80 specifically comprises:
step 81, judging whether the current voice interference is partial audio current voice interference;
step 82, when the current voice interference is judged to be partial current voice interference, determining the current interference duration according to the voice information to be interfered, and recording any voice packet to be interfered as the initial position of the current voice interference;
step 83, when it is determined that the current voice interference is not part of the current voice interference, marking a first voice packet to be interfered of the voice information to be interfered as the initial position, and marking a duration of the voice information to be interfered as the current interference duration;
step 84, generating the current voice interference information according to the voice information to be interfered, the initial position, the current interference duration, the current interference data, the current interference level and the first attenuation factor;
and step 90, sending the current voice interference information.
3. The method for simulating interference to noise in air voice communication according to claim 2, wherein the step 84 specifically includes:
step 841, acquiring the corresponding voice data according to the voice information to be interfered, the starting position and the current interference duration, and recording the voice data as the data to be interfered;
step 842, generating analog interference voice data according to the data to be interfered, the current interference data, the current interference level and the first attenuation factor;
step 843, when the analog interference voice data is judged to be larger than a first threshold value or smaller than a second threshold value, recording the first threshold value or the second threshold value as the analog interference voice data;
step 844, generating the current voice interference information according to the voice information to be interfered and the analog interference voice data,
wherein the first threshold is greater than the second threshold.
4. The method for simulating interference to noise in air voice communication according to claim 3, wherein the step 84 further comprises:
step 845, calculating a second attenuation factor according to the simulated interference voice data and the first threshold value or the second threshold value;
step 846, updating the second attenuation factor to the first attenuation factor.
