Acoulatis | Making Sound Insulation Predictions Accessible for Timber Structures
Mass timber construction is becoming an increasingly popular method because of the multiple advantages it can bring such as reduction of the carbon footprint of the built environment. Nevertheless, the use of mass timber poses some rather unique challenges in terms of acoustics. Mass timber, including cross-laminated timber (CLT), offer poor acoustic isolation levels itself, particularly at lower and mid frequencies, where the mass timber wall and floor panels transmit noise very efficiently and make it challenging to comply with local building regulations. The panels must be supplied with additional floor, wall and ceiling assemblies.
Lab test data helps in understanding how different variables impact both, airborne sound reduction and impact noise isolation of some of floor ceiling assemblies. However, having a reliable prediction model to rely on will allow the experiment of different variables and setups to reach conclusions more efficiently, cost-effectively, and quickly.
Acoulatis by Sonusoft is a sound insulation prediction tool, primarily using CLT as base for load-bearing structure and offering the ability to calculate airborne sound insulation of walls, and both the airborne and the impact sound insulation of floors in third-octave frequency bands.
During this webinar, we will explore the theoretical modelling behind Acoulatis, an algorithm based on empirical equations combined with characteristic acoustic models, verified against numerous laboratory measurements in accredited laboratories; followed by a live demonstration of its intuitive interface and easy-to-use features.
CDM Stravitec will also provide a rapid overview of the key findings from an extensive lab test campaign on various floor-ceiling assemblies and compare these results to Acoulatis' predictions.
Learning objectives:
- Be aware of Sonusoft and CDM Stravitec’s purpose and activity in building acoustics.
- Increase understanding of Acoulatis prediction tool and benefits of predicting sound insulation, by better understanding the theoretical modelling behind.
- Understand the main challenges acoustically on a CLT construction and how to overcome those with floor-ceiling assemblies (dissect different variables that result in different setups and their impact on the acoustic performance).
