Plan sound control before closing the basement ceiling. Voices and television sound travel differently from footsteps and furniture movement, so first identify the noise you want to reduce. A suitable floor and ceiling assembly can combine sound-absorbing insulation between joists, drywall and resilient mounting that limits vibration transfer. The details work together; insulation alone does not guarantee a quiet room.
Review other sound paths, including the stair opening, doors, ducts and gaps around services. Soft furnishings can reduce echo within the basement, while sound isolation addresses transmission to adjoining rooms. Discuss your goals during basement renovation planning so the ceiling design, lighting and mechanical access can be considered together. Ask what improvement the proposed assembly is designed to deliver, rather than expecting complete silence.
