Measure the acoustics of a room... with a simple clap ClapReverb lets you instantly evaluate the reverberation time (RT) of an enclosed space — a key factor in determining a room’s acoustic quality. Is the room too echoey? Or too dry? Get the answer in just a few seconds. Simple, fast, and precise With a clean design and intuitive interface, all it takes is a quiet moment and five hand claps. Place your phone or tablet at the center of the room, wait for the signal, and clap your hands (slightly cupped palms). The app analyzes the relevant frequencies and provides a clear picture of the room's acoustics. A professional tool, accessible to everyone Whether you’re an architect, interior designer, engineer, teacher, musician — or simply curious — ClapReverb is for anyone who wants to integrate acoustics into their projects. Easily compare your results to typical reference values and decide if acoustic treatment is needed. Scientifically validated The app’s results have been verified through a rigorous experimental protocol, presented at the 26th International Congress on Sound & Vibration.
