Acalc is built by a acoustical engineers for people who work in acoustics.

We have a long and ambitious list of tools that will eventually make up the Acalc suite. Acalc hopes to replace your spreadsheets, your expensive one-task software packages, and even some of your measurement equipment. Everything connected through uniform data formats and brought into a single place to reduce context switching to the fullest extent possible. And also to reduce software costs. See the About page for our current plans.

This is very early software, so please don't expect much. We want to get this out in front of people so that we can start getting very valuable user feedback.

We're launching Acalc with a tool that we've wanted for decades: Partitions. Edit a partition design in an intuitive GUI, search for test reports for similar partitions, and get performance predictions from a neural network that's been trained on every TL test report we could find.

We know there are many more test reports out there. The more we have in the library, the easier they will be to find and the better the model will be at predicting. If you have some that are in the public domain and should be added to the Acalc library, please send a .pdf. We're especially interested in lab tests of weird materials and assemblies.

It's possible to create a private library if you have a collection of test reports that you'd like to keep out of the public domain. The search will work on all libraries you have access to simultaneously. If you'd like to set up a private library, let us know.

Right now, registering as a user will simply show us your interest, which we'd deeply appreciate. It's not required for any of the site's functionality yet. At no point will you put on any mailing lists and your email address will never be sold or traded to anyone.
