Amplify Sound

For the duration, you cause an amplification of all sounds within or passing through a 20-foot-radius sphere centred on a point or a creature you choose within range. Those creatures within the spell's area do not notice the increased amplification. Thus, anyone whose voice is amplified remains unaware of the increase in volume. Any creature inside the sphere has advantage on Wisdom (Perception) checks based on hearing and is vulnerable to thunder damage. An unwilling creature can make a Constitution saving throw to negate the spell.

Amplify counters and dispels the silence spell, and is also countered and dispelled by it.
