Impulso Lite allows you to measure the acoustic response of your room using your iPhone. You can visualize the measured reverberation time (RT) in octave bands and then simulate how the acoustic response of your room will be improved when adding artnovion acoustic products. You can enter room dimensions and select the type of room you are designing for. The app will then tell if your room meets the expected RT and you can select products to optimize the response accordingly. Impulso Lite allows you to take a measurement with an internally generated signal if you are able to play it via a loudspeaker system, or using an external impulse source, such as a balloon, if you don’t. Compatible with built-in or external microphones. Check out Impulso Pro for detailed plots of energy time curves, to check for undesirable reflections, a frequency plot, which you can zoom in and a table with the acoustic parameters of your measurements such as C80, D50, STI and Bass Ratio. Impulso Pro also adds tramlines to the RT plot so you can fully optimize the response to meet the criteria for the room type selected. You can also display the spectral response of the microphone input using the new Real Time Analyzer. Check more at www.artnovion.com

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.
