Example Embodiment
[0034] Example one
[0035] See figure 1 As shown, figure 1 Shown is a voice noise reduction method for a terminal. The terminal includes a first microphone and a second microphone. The method includes:
[0036] S11. Determine whether the sound pressure level of the noise at the location of the terminal is lower than a preset sound pressure level threshold through the second microphone, or determine whether the signal-to-noise ratio of the noise at the location of the terminal is higher than a preset threshold through the second microphone SNR threshold;
[0037] Among them, the first microphone is the main microphone, used to collect voice and environmental noise; the second microphone is the secondary microphone, used to collect environmental noise. The sound pressure level is the loudness of the sound, and its unit is decibels, which is a calculation unit for measuring the loudness of the sound. The signal-to-noise ratio is the ratio of the normal sound signal to the noise signa...
Example Embodiment
[0047] Example two
[0048] Such as figure 2 As shown, figure 2 It is a terminal proposed by the present invention. The terminal includes a first microphone 11 and a second microphone 12. The terminal also includes: a determining module 13 for determining whether the sound pressure level of the noise at the location of the terminal is low through the second microphone 12 Determine whether the signal-to-noise ratio of the noise at the location of the terminal is higher than the preset signal-to-noise ratio threshold at the preset sound pressure level threshold or through the second microphone 12; the first noise reduction module 14 is used for the judgment of the judgment module When the result is yes, the voice is processed for noise reduction through the first microphone 11.
[0049] Among them, the first microphone 11 is the main microphone for collecting voice and environmental noise; the second microphone 12 is a secondary microphone for collecting environmental noise. The s...
