Soundproof

Soundproof is a Pokémon ability introduced in the Third Generation. It gives Pokémon with this ability immunity to sound-based attacks.

Effect
Soundproof prevents all the effects of sound moves on the user, granting them immunity from them. As sound attacks are one of the few ways to bypass a substitute, it can be helpful defensively. In Pokémon FireRed and LeafGreen, the Poké Flute cannot be used to wake up a sleeping Pokémon with this ability.

Descriptions
Generation III - Avoids sound-based moves.

Generation IV - VI - Gives full immunity to all sound-based moves.
