Acoustics Made Easy – Our Glossary
The world of acoustics is complex – shaped by physical terminology, technical measurement parameters, and regulatory requirements. In our glossary, you will find clear explanations of key terms related to room acoustics, sound insulation, and sound optimization.
Whether you're an architect, planner, building owner, or simply interested in acoustics: this reference guide helps you understand concepts, better evaluate materials, and make well-informed decisions. Technically precise, clearly formulated – and regularly expanded.
Dive into the language of acoustics.
A
A-Rating
The A-weighted sound pressure level is the weighted average of the sound pressure level (dB) as a function of the frequency of a sound. This weighting takes into account the human ear's ability to perceive sound pressure levels or tones of different frequencies with varying intensity. Sensitivity is particularly high in the mid-frequency range, the range of human speech. Almost all regulations and guidelines specify values in dB(A).
B
Building acoustics
Building acoustics is a field of building physics or acoustics that deals with the effect of structural conditions on the propagation of sound between the rooms of a building or between the interior and exterior of the building.
