Paragon Acoustic Consultants had been reviewing different room acoustics software packages to standardise the software used within the practice. 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. 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. 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. ​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. 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 find very useful the advanced physics engine for sound propagation which allows for wave-based simulations (plane or spherical) considering also atmospheric refraction.

This enables OTL to achieve accurate results especially in large scale setups encountered in environmental studies. 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. Such features which have been utilized by the members of our Audio and Acoustic Technology group during research projects.

The support by the OTL team was extremely helpful and their response immediate, tackling queries at personal level and providing educational webinars for the students. Although designed for demanding Acoustics applications, Olive Tree Lab has been instrumental in my research and work. Despite its hugely detailed modeling of acoustic properties, primarily addressed to acousticians, through its intuitive interface, it has also proven invaluable for architectural design.

Furthermore, the Mediterranean Acoustics team have vastly exceeded my expectations for 'after sales service' and provided a rare blend of scientific expertise and personal care – giving true meaning to the word 'support'.

Use EASE to plan exactly where to place and aim your Williams AV infrared emitters before arriving on-site, utilizing such virtual features as: full rotation and aiming of the emitter, summation of multiple emitters, mapping on audience areas and walls, and shadowing of building elements. Once placement of Williams AV infrared emitters has been optimized, contour mapping and coverage of the audience area also can be examined to ensure proper signal-to-noise ratios are being achieved, and that the right emitter is being specified for the project.
