Our cockatiel was noisy... very noisy. When we let it out of its cage (which I no longer approve of) it would perch on the curtain rail and mess down the curtains. My father did not enjoy cleaning up after it (I was between 5 and 10 years old when we had the bird).
So noisy, messy and I no longer approve of keeping birds in relatively small cages. I would not recommend a cockatiel unless you have a large space for them to fly, which is perhaps separated from your home to avoid the noise.
