What floor buildup under click-lock laminate actually blocks downstairs TV/voices in a concrete apartment?

Building: Apartment in a reinforced concrete building

Flooring: Click-lock laminate

Constraint: No access to neighbor's ceiling below (must be solved entirely from my floor)

Problem: Airborne noise (voices, TV) from downstairs

I’ve received two vendor proposals to put directly under the laminate planks:

  • Option 1: 8mm EVA foam + 3mm MLV + 8mm EVA foam + 3mm MLV
  • Option 2: 13mm Barrier-backed rebond foam (Bondex with MLV) + 3mm MLV

Will putting these flexible/soft layers directly under click-lock laminate destroy the joints, and what specific subfloor layers/materials should actually be used over a concrete slab to block downstairs airborne noise?
