In my script, these two lines:

    var newAlpha : float = 1.0 - (health / startingHealth);
	staticRenderer.material.color.a = newAlpha;

change the alpha of a material. I need to add another 2 lines like these, which will change the volume of an audio source. Any ideas?

Try this:

var newAlpha : float = 1.0 - (health / startingHealth);
    staticRenderer.material.color.a = newAlpha;
audio.volume = newAlpha;

Edit:
You need to alternate between 0.0f and 1.0f in audio.volume see this Audio Volume for more information
