Use a random number with either a switch statement, or a compound if-else statement, or an array for the sound file names as String objects or for the GreenfootSound objects.

                Greenfoot.playSound("gered.wav");
            }
            else if(rand == 1)
            {
                Greenfoot.playSound("gered1.wav");

    else

        Greenfoot.playSound("gered1.wav");
     }
}
With only two possibilities, if not the one, then the other (no need for the 'if' after the 'else'). Even with more than two possible sounds, you can avoid the 'rand' variable:

if (obect != null)
{
    switch(Greenfoot.getRandomNumber(3))
    {
        case 0:  Greenfoot.playSound("gered.wav"); break;
        case 1:  Greenfoot.playSound("gered1.wav"); break;
        case 2:  Greenfoot.playSound("gered2.wav"); break;
    }
}

@RyanOseris, please do not revive old discussion threads. Rather, start a new one. At any rate 'object' was assigned a value prior to the code given -- probably by way of using the 'getOneIntersectingObject' method:
?
1
Actor object = getOneIntersectingObject(<< class name >>);
