如何使用麦克风在Android应用程序中录制以分贝为单位的声音强度？

<uses-permission android:name="android.permission.RECORD_AUDIO" />

int audioSource = MediaRecorder.AudioSource.MIC;
int sampleRate = 44100;
int channelConfig = AudioFormat.CHANNEL_IN_MONO;
int audioFormat = AudioFormat.ENCODING_PCM_16BIT;
int bufferSize = AudioRecord.getMinBufferSize(sampleRate, channelConfig, audioFormat);

AudioRecord audioRecord = new AudioRecord(audioSource, sampleRate, channelConfig, audioFormat, bufferSize);

audioRecord.startRecording();

short[] buffer = new short[bufferSize];
int readSize;
double sum = 0;

while (isRecording) {
    readSize = audioRecord.read(buffer, 0, bufferSize);
    
    for (int i = 0; i < readSize; i++) {
        sum += buffer[i] * buffer[i];
    }
    
    if (readSize > 0) {
        double rms = Math.sqrt(sum / readSize);
        double db = 20 * Math.log10(rms);
        
        // 处理分贝值，例如更新UI界面显示
        // ...
    }
}

audioRecord.stop();
audioRecord.release();
