When it comes to the soundproofing of new build flats, the Sound Transmission Class (STC) rating is a critical metric used to quantify how well a building attenuates airborne sound.

STC ratings are an integral part of the Robust Details (RD) certification process, providing a standardized measure of a partition’s ability to reduce noise.

The higher the STC rating, the more effective the structure is at blocking sound transmission.

Under RD specifications, the STC ratings for airborne noises must meet or exceed certain thresholds to ensure a significant reduction in sound transmission.

For example, walls and floors between living spaces typically require STC ratings of 40 or above, which means that loud speech can be faintly heard but is generally not intelligible.

In practice, many new constructions aim for even higher STC ratings, sometimes reaching up to 50 or 60, which indicates superior soundproofing where most common noises are muted to a whisper.

Impact noise, on the other hand, is evaluated using Impact Insulation Class (IIC) ratings, which assess a floor/ceiling assembly’s ability to reduce the transmission of impact sounds, such as footsteps or dropped objects.

RD standards stipulate that these ratings also meet minimum requirements to ensure that daily activities from upper floors do not unduly disturb residents below.

IIC ratings are complementary to STC ratings and are just as crucial for overall acoustic comfort in multi-story buildings.

To achieve these high STC and IIC ratings, RD-compliant flats incorporate a variety of sound-dampening materials and construction techniques.

These can include the use of dense insulation materials, decoupled framing structures, resilient underlayments for flooring, and other specialized acoustic treatments.

The exact materials and methods used can vary depending on the specific RD chosen for the project, as each RD contains detailed specifications tailored to its unique soundproofing solution.

It is important to note that while RD provides robust guidelines for construction, the actual STC and IIC ratings achieved can be influenced by the quality of construction and adherence to the specified details.

Consequently, builders and developers must follow RD specifications meticulously to ensure that the intended soundproofing performance is realized in the finished building.
