The just noticeable difference (JND) for frequency is proportional to the starting frequency, following Weber's Law. Since the difference needed to notice a change from 100 Hz was 1 Hz (a 1% increase), the same proportional change (1%) would apply to a 1000 Hz tone, making it 1010 Hz for the change to be noticeable.
