IsoCal App

Take the guesswork out of building acoustics

Let IsoCal take care of the calculations and leave you with the results, so you can focus on your design.

Acoustics isn’t just about mathematics and physics, it’s about creating a space that sounds as good as it looks!

The app is fitting for architects, engineers and everyone else. Design and test your construction in seconds. View the acoustic behaviour to avoid expensive and unforseen consequences later on.

Version 1.4.5 – Sep 16, 2024

Fixes

  • Fixed how the ‘practical absorption coefficient’ is calculated as it showcased wrong results before in certain cases.
  • Fixed an issue where the m2 calculation under ‘Settings’ would show too many decimals.
  • Fixed an issue where the critical frequency would not calculate correctly in the ‘Double Wall’ calculation module when using both Layer 1 and 2.

New Content

  • Added a ‘Copy data’ button for both Single Panel and Double Wall result pages. The user can now press and hold the copy icon to copy the data to the clipboard

Changes

  • Overhauled how the results are showcased for Single Panel, Double Wall and Absorption coefficient. It now has better structure and more detail.
