They are frequently used to create soundproof enclosures for pumps, speaker boxes, and generators due to their dispersed grain structure, which provides a smooth-to-the-touch surface capable of filtering out the sound.

MDF works well for walls in offices, apartment complexes, and studios, and they are denser than other alternatives, such as OSB and plywood (Oriented Strand Board). This amazing substance blocks out sounds to create a tranquil, whisper-quiet atmosphere.

Due to its thickness, high density, and STC rating, Medium Density Fiberboard is renowned for having exceptional soundproofing properties. MDF can adequately absorb all sound frequencies, which is something most of its substitutes find difficult to do.

The STC rating of MDF is 33. On the other hand, solid wood has an STC rating of roughly 30-32 (based on multiple factors, such as wood density).
