Challenges with Accurate Sound Insulation Predictions
Building acoustic and sound insulation predictions require not only proper calculation methods but also reliable acoustic input data. Professionals face two key challenges: 1) Predicting sound insulation of building elements like walls, floors, and partitions. 2) Supplying ISO 12354-based tools with structured and validated acoustic datasets.
​
Without reliable input data, even advanced ISO 12354 software cannot produce dependable results. Sonusoft addresses both sides of these challenges with Acoulatis and the SOAB Database.

Acoulatis – Sound Insulation Prediction Software
Acoulatis is a modular building acoustics prediction tool developed for acoustic consultants, engineers, researchers, architects, and manufacturers.
It enables third-octave airborne and impact sound insulation predictions of floors and walls, and supports many materials like timber joists, CLT, LVL, concrete and steel.
Acoulatis predicts the acoustic performance of individual constructions with ease. This makes it particularly useful during early design stages, product development and research applications.
Acoulatis can generate prediction data that may later be structured for use in ISO 12354 workflows.
SOAB Database – Acoustic Input Data for ISO 12354 Software
The SOAB Database is a structured acoustic database designed for use in ISO 12354-based building acoustics software platforms. Many ISO 12354 calculation tools require additional constructions from manufactures with acoustic data in third-octave frequency bands.
The SOAB Database provides standardized acoustic input data of more than 1500 building elements from manufactures that is aligned with ISO 12354 workflows. This allows consultants and engineers to improve calculation reliability, reduce manual data handling and maintain consistency across projects. The SOAB Database is compatible with CadnaB, SONarchitect and BASTIAN.
CadnaB is developed by DataKustik GmbH with similar features as its predecessor BASTIAN. Together with our database, it becomes a powerful tool to calculate the building acoustic parameters.
SONarchitect is developed by Sound of Numbers and with it, you can evaluate the sound insulation of the entire building according to the ISO 12354 series. Our database is integrated within the Acousticbase database that the program uses.
BASTIAN has been used in the Nordic countries since 2000 to calculate sound insulation in buildings. The software is still used by many consultants but it is no longer maintained by the supplier DataKustik GmbH.
Integrated Acoustic Workflow
While Acoulatis and the SOAB Database are independent services, they support complementary stages of the building acoustics workflow.
​
Acoulatis predicts the sound insulation of individual constructions in detailed third-octave frequency band results, along with an appoximated field value prediction with flanking sound transmission, good for early stages.
​
SOAB Database supplies structured input data to ISO 12354 software which predict with flanking sound transmission modeling, enabling whole-building acoustic calculations.
Together, they are powerful tools that strengthens reliability across the entire design process for building acoustic experts. Don't hesitate to contact us for more information!
Sonusoft specializes in professional tools and structured data solutions for building acoustics. We focus on empirical prediction models and practical tools for real-world acoustic projects.
Our mission is to support accurate and reliable building acoustic prediction — from element-level modeling to ISO 12354 building calculations.​
