The primary benefit of using an underlayment with laminate flooring is noise reduction. Laminate flooring, while affordable and visually appealing, can often produce a tapping or hollow sound when walked on. An underlayment acts as a cushioning layer that absorbs sound, thereby minimizing noise levels and creating a quieter environment. Additionally, this layer can also provide some level of cushioning underfoot, which enhances comfort when standing or walking on the floor.

While options such as cost-saving, improving aesthetics, and moisture control have merits, they are not the primary function of an underlayment. Cost-saving may arise from the overall installation approach, but underlayment itself often adds to the initial costs. Improving aesthetics is not directly achieved through an underlayment, as it is typically hidden beneath the laminate. Moisture control is also a benefit, especially in certain environments; however, it doesn't take precedence over the crucial role of noise reduction that an underlayment provides in enhancing the laminate flooring experience.
