An example script (you will have to fill in the details):

 /*You need to set the emit of this particle system to 0 at the editor,
 so it will not emit at all during play-mode by itself*/

 public ParticleSystem thruster; 

 /* The audio, I am not sure about this one as I have little experience 
 with audio (but you can google on how to play audio in unity*/

 public AudioSource audio;
 
 void Update() {
 
    if( Input.GetKey( KeyCode.Z) ) {
       thruster.Emit(10); //Emit some particle
       audio.Play();
    }
 }
