Impulso Architect vs IsoCal

With Impulso Architect you can take a quick and simple measurement of the acoustic response of your room using your iPhone. Reverberation time is given in the important 500Hz – 2kHz octave bands. You can enter the dimensions of your room and it’s general use. Impulso Architect will then give you a target RT and allow you to simulate how you can meet it with products from the artnovion catalogue. Compatible with built-in or external microphones, and you can either use an external impulse source such as a balloon or drive a loudspeaker system with the internal measurement signal.

IsoCal is a prediction tool for calculating the sound reduction index of single walls with no cavity and double walls with a cavity between the leafs. It is possible to design walls with multiple leafs and different cavity/boundary connections (rigid connections, steel studs, staggered studs, etc.), different porous sound absorption material in the cavity of a double wall and predict the sound reduction index given as a Rw value in decibels [dB]. IsoCal comes built in with a catalog of well known material and porous material to use for designing the wall for optimal sound reduction. The user can also insert own materials in order to expand own personal database. IsoCal also provides a calculator for the prediction of absorption coefficients of porous materials. A simple calculator that lets the user choose the porous material thickness, air gap behind the porous material and more.
