SOTTOVOCE: THE SOUND-ABSORBING PLASTER FOR SPACES WHERE ACOUSTIC COMFORT MAKES THE DIFFERENCE

In shared spaces, noise is not just a nuisance: it is a factor that affects the quality of the experience, concentration, and the overall perception of the environment. Classrooms, cafeterias, restaurants, conference halls, places of worship and hospitals are contexts where reverberation can compromise speech clarity and generate discomfort.

To provide a concrete response to these needs, Sottovoce was developed — Edilteco’s lightweight sound-absorbing plaster designed to control acoustic reverberation in indoor environments.

A surface that absorbs sound

Sottovoce is a spray-applied sound-absorbing plaster formulated with hydraulic binders, lightweight components and specific additives that enable it to absorb sound waves and reduce sound reflection within spaces.

The result is a more balanced and orderly atmosphere:

• improved speech intelligibility,

• reduced acoustic fatigue,

• greater comfort for those who use the space every day.

In a classroom, this means supporting learning; in a conference hall, ensuring clarity during presentations; in a cafeteria, reducing background noise; in a liturgical space, preserving a sense of focus and quality of listening.

Complete aesthetic integration

One of the main advantages of Sottovoce is its ability to integrate seamlessly into the architecture.

Unlike traditional panel-based sound-absorbing systems, Sottovoce creates a continuous, uniform surface free of visible joints, adapting even to irregular or complex geometries.

It is available in white, grey or anthracite grey finishes, offering a clean and elegant aesthetic result suitable for both public buildings and private settings.

A conscious choice

Sottovoce is formulated with regranulated EPS, contributing to a more responsible approach aligned with circular economy principles.

With its low density and good thermal conductivity, it also contributes to the overall comfort of the environment, combining acoustic benefits with building quality.
