no ignore background noise

Hi, what congiguration I need in my code for ignore background noise? Because with small noises, it thinks someone is talking. Regards. //const SILENCE_THRESHOLD = 0.015; const SILENCE_THRESHOLD = 0.060; const SAMPLE_RATE = 48000; const CHANNEL_DATA_LENGTH = 128; const MAX_SEGMENT_LENGTH = 10; // seconds const MIN_TALKING_TIME = 2; // seconds const AMPLITUDE_WINDOW = 0.5; // seconds

class WorkletProcessor extends AudioWorkletProcessor { constructor() { super(); this._bufferSize = MAX_SEGMENT_LENGTH * SAMPLE_RATE; this._buffer = new Float32Array(this._bufferSize); this._writeIndex = 0;

this._amplitudeHistorySize = Math.floor(
  (AMPLITUDE_WINDOW * SAMPLE_RATE) / CHANNEL_DATA_LENGTH
);
this._lastAmplitudes = new Array();
this._amplitudeSum = 0;
this._stopped = false;
this._lastEventState = null;
this._lastEventTime = new Date();
this._talkingTime = 0;

this.port.onmessage = (event) => {
  if (event.data.type === "stop") {
    this._stopped = true;
    this.port.postMessage({ type: "silence" });
    if (this._lastEventState !== "silence") {
      //this.port.postMessage({ type: "silence" });
    }
    this._maybeSendSegment();
  } else if (event.data.type === "start") {
    this._talkingTime = 0;
    this._writeIndex = 0;
    this._stopped = false;
    this._lastEventState = null;
    this._lastEventTime = new Date();
  }
};

}

_maybeSendSegment() { if (this._talkingTime > MIN_TALKING_TIME) { console.log("Sending segment"); this.port.postMessage({ type: "segment", buffer: this._buffer }); } }

process(inputs, outputs, parameters) { if (this._stopped) { return true; } const channelData = inputs[0][0];

const amplitude =
  channelData.reduce((s, v) => s + Math.abs(v), 0) / channelData.length;

if (this._lastAmplitudes.length >= this._amplitudeHistorySize) {
  const front = this._lastAmplitudes.shift();
  this._amplitudeSum -= front;
}

this._lastAmplitudes.push(amplitude);
this._amplitudeSum += amplitude;

const averageAmplitude = this._amplitudeSum / this._lastAmplitudes.length;

this._buffer.set(channelData, this._writeIndex);
this._writeIndex += channelData.length;
const remainingBufferSize = this._bufferSize - this._writeIndex;

if (averageAmplitude > SILENCE_THRESHOLD) {
  if (this._lastEventState !== "talking") {
    this._lastEventState = "talking";
    this.port.postMessage({ type: "talking" });
  }
} else {
  if (this._lastEventState !== "silence") {
    this._talkingTime += (new Date() - this._lastEventTime) / 1000;
    this._lastEventState = "silence";
    this._lastEventTime = new Date();
    this.port.postMessage({ type: "silence" });
  }
}

// If we have a silence or are running out of buffer space, send everything
// we have if it's long enough, and then reset the buffer.
if (
  (averageAmplitude <= SILENCE_THRESHOLD &&
    this._talkingTime > MIN_TALKING_TIME) ||
  remainingBufferSize < channelData.length
) {
  this._maybeSendSegment();
  this._buffer = new Float32Array(this._bufferSize);
  this._writeIndex = 0;
  this._talkingTime = 0;
  this._lastEventTime = new Date();
}

return true;

} }
