Catch the key code and then call your function. This example catches the ESC key and calls your function:

function getKey(key) {
    if ( key == null ) {
        keycode = event.keyCode;
    // To Mozilla
    } else {
        keycode = key.keyCode;
    }
    // Return the key in lower case form    
    if (keycode ==27){
        //alert(keycode);
        pauseSound();
        return false;
    }
    //return String.fromCharCode(keycode).toLowerCase();
}
$(document).ready( function (){
    $(document).keydown(function (eventObj){
        //alert("Keydown: The key is: "+getKey(eventObj));
        getKey(eventObj);
    });
});

You'll need JQUERY for this example.
