To sign "quack," bring your dominant hand up to the front of your mouth. Keep your four fingers straight and pressed together, and place your thumb straight underneath them, forming a shape like a bird's beak. Open and close your fingers and thumb together twice, mimicking a duck's bill opening and closing as it makes a sound.
Sign 'duck' by placing your index and middle fingers over your thumb at your mouth, then emphasize the action by signing 'quack' using your whole hand opening and closing.
Point to your ear for 'hear,' use the sign for 'loud,' and then perform the sign for 'quack' right in front of your mouth.
Sign 'baby' and 'laugh,' then sign 'quack' to show exactly what animal sound caused the baby to giggle.

They are very similar, but 'duck' is usually signed with just the index and middle fingers closing against the thumb right on the mouth. 'Quack' often uses the whole flat hand opening and closing to emphasize the action or the sound itself.
You don't need to use your voice, but mouthing the word 'quack' or slightly opening and closing your lips in time with your hand can add great non-manual expression to your signing, especially when storytelling.
'Quack' is typically a one-handed sign performed with your dominant hand. Using two hands isn't standard for this word unless you are playfully mimicking two ducks talking to each other in a children's story!
