If function is called too many times

i’m using ml5 for a project, and what i’m trying to achieve is everytime my nose is detected inside an ellipse, a song starts and the ellipse moves with a perlin noise effect.

The problem is the “if function” is called too many times and I think it deteriorates the sound bc I think it starts it multiple times. Also even when my nose is inside the ellipse it keeps saying “false” and then “true” in the console and I don’t know why? What would be the best way to code this to make it work smoothly?

checkCollision(points) {
    points.forEach((keypoints) => {
      keypoints.forEach((keypoint) => {
        const pos = keypoint.position;
        const d = dist(pos.x, pos.y, this.x, this.y);
        const hasTriggered = d <= this.radius * 0.5;
        if (hasTriggered) {
          this.sound.play();
          this.maxnoise = lerp(this.maxnoise, 50, 0.05);
          console.log("true");
        } else {
          console.log("false");
          this.sound.stop();
          this.maxnoise = lerp(this.maxnoise, this.maxnoiseafter, 0.05);
        }
      });
    });
}

this is what my console looks like when i’m inside the ellipse and supposed to trigger the effect and the sound
