Functioning room acoustics consist of a fine balance between sound absorption and reflection. Total sound absorption, for example, would make it difficult for sound to travel through a room, while no sound absorption at all would result in echos and make a room sound unpleasantly loud. The acoustics of an echoing room can be improved in two ways: either by absorbing sound or by diffusing reflected sound.
Our acoustic panels are classified as sound absorption class C, “highly absorbent”, according to the ISO 11654 standard. The tests were carried out independently at the Turku University of Applied Sciences in 2020. You can read the test results report here. The acoustic properties of our acoustic panels are a combination of sound absorption and diffusion: the acoustic fabric absorbs sound while the design of the slats disperses sound reflections.
In class C, 60-75% of the energy carried by sound waves is absorbed and the rest is reflected from the surface. This absorption class ensures improved room acoustics even in the most acoustically challenging spaces. The more acoustic surface area there is, the greater the impact. For example, installing a ceiling panel is an easy way to get an essential part of a room’s acoustics right, already at the construction stage.
