The invention discloses an automobile air conditioner blower noise control system, which comprises a sound acquisition device, a data processing device, a noise analysis device and a blower control device which are connected in sequence, and is characterized in that the sound acquisition device is used for acquiring sound signals, converting the sound signals into audio files and storing and transmitting the audio files; the data processing device is used for processing the acquired audio file to obtain a loudness and frequency linear spectrogram of the audio file; the noise analysis device evaluates the sound frequency curve according to the sound linear spectrogram; and the blower control device controls the blower rotation speed according to the evaluation result output by the noise analysis device. The control system can control the rotating speed of the air conditioner blower in real time, so that the noise is controlled within a specified range.

    本发明公开了一种汽车空调鼓风机噪声控制系统,包括按顺序连接的声音采集装置、数据处理装置、噪声分析装置和鼓风机控制装置,其中,声音采集装置用于采集声音信号,转化成音频文件,存储并传输音频文件;数据处理装置用于对采集到的音频文件进行处理,得到其响度和频率线性谱图;噪声分析装置根据声音线性谱图对声音频率曲线进行评价;鼓风机控制装置根据噪声分析装置输出的评价结果控制鼓风机转速。上述控制系统可以实时控制空调鼓风机的转速,使其噪声控制在规定范围之内。
