Enhanced Acoustic Simulator for Engineers (EASE) is an engineering design and analysis software for optimizing acoustics. [1] The full product is licensed and copy protected. It can perform complex analysis in three-dimensional space. There is a free-to-use web-based version available for two-dimensional analysis with limited geometry options. [2]
Room acoustics is a subfield of acoustics dealing with the behaviour of sound in enclosed or partially-enclosed spaces. The architectural details of a room influences the behaviour of sound waves within it, with the effects varying by frequency .
Room modes are the collection of resonances that exist in a room when the room is excited by an acoustic source such as a loudspeaker. Most rooms have their fundamental resonances in the 20 Hz to 200 Hz region, each frequency being related to one or more of the room's dimensions or a divisor thereof. These resonances affect the low-frequency ...
Auralization is a procedure designed to model and simulate the experience of acoustic phenomena rendered as a soundfield in a virtualized space. This is useful in configuring the soundscape of architectural structures, concert venues, and public spaces, as well as in making coherent sound environments within virtual immersion systems.
An acoustician version has been offered as Smaart Acoustic Tools, however as of Smaart v7.4, Acoustic Tools have been included within the Impulse Response mode of Smaart. A standalone sound pressure level monitoring only version called Smaart SPL was released in 2020.
The use of finite elements enabled the simulation of complex noise sources, the combination of multiple materials in the same model and the handling of multi-million degrees-of-freedom models. The initial target application was the prediction of the acoustic transmission through complex partitions (hence the name ACTRAN: ACoustic TRANsmission).
