After you have entered your room data, our calculator will provide you with important key figures:
Room volume: The size of your room in cubic meters (m³).
Floor area: The floor area of your room in square meters (m²).
Estimated initial reverberation time / initial absorption (Easy Mode): A first estimate of how reverberant your room currently is, or how much sound is already being absorbed, based on typical surfaces.
Current reverberation time / total absorption (expert mode): Shows the acoustics of your room taking into account all surfaces you have added (walls, floor, ceiling, windows, furniture, people, etc.).
Target reverberation time (T60) or minimum absorption area (A_min): This is the recommended value according to DIN 18041 or a general recommendation for your room's use. A reverberation time that is too long means the sound remains in the room for too long (reverberation). An insufficient absorption area also leads to poor acoustics.
Required additional absorption: The most important value! It shows you how much additional sound absorption in square meters (m²) your room needs to achieve the target values.
