The interface for immediate comparison of analytical results with standardized approximations (ISO standards) or simplified computational methods such as ray tracing and image-source models allows for comprehensive evaluations in multiple levels of physical detail. This enables OTL to achieve accurate results especially in large scale setups encountered in environmental studies.

I find very useful the advanced physics engine for sound propagation which allows for wave-based simulations (plane or spherical) considering also atmospheric refraction. The program is user-friendly and incorporates an advanced high-level 3D designer tool for setting up virtual acoustic environments, allowing easy setting up of case studies and extracting results and maps for radiation and transmission for noise and other sources. I have been using the OTL Lab application for a number of years, mainly for teaching and demonstrations at undergraduate and postgraduate courses in acoustics and noise control. Mediterranean Acoustics R&D. At this stage the modelling functions for outdoor sound have not been used, however, having watched demonstrations by Mediterranean Acoustics via computer link–up the external modelling sections of the software look as impressive as the room acoustics modelling. Having rented the software and modelled a number of relatively complex room acoustic projects, we are impressed with the software and in particular the very professional back-up and support provided by P.E. Various room acoustic packages were considered, however, a number of the software packages considered proved unfavourable due to limitations of room geometries that can be modelled, limited calculation outputs and general concerns that the software was unnecessarily difficult to use for even straightforward tasks. This practice has reviewed Olive Tree Lab Suite and found the software to be user friendly whilst providing a very high level of functionality.

Paragon Acoustic Consultants had been reviewing different room acoustics software packages to standardise the software used within the practice.
