Olive Tree LabVersion 4.4 -3D Acoustical Software Suite

SHARE

OTL Suite is a suite of 3D acoustical software applications integrated in one working environment. It`s the first ever acoustical software application which offers such flexibility among calculations in various fields of acoustics, including non-homogeneous meteorological conditions, within the same environment.

Most popular related searches

These applications are: Room Acoustics, Open Plan Office, Outdoor Sound Propagation, Multilayered Structure Builder, and Sound Distribution and Scattering Polar Plotter. 

Think of OTL-Suite as the equivalent of MS Office in Acoustics - many applications talking to each other seamlessly and no more transferring incompatible data from one application to another. 

Why Olive Tree Lab?

Because:

  • After years of using third party software and mismatch between measured data and predictions, we have developed a software where practice matches theory .
  • It`s developed from an acoustical engineer’s point of view.
  • Although standards are needed, there are advanced acoustical methods beyond standards, which we additionally apply. 
  • We believe in accuracy and not estimation for both the designer and the client.
  • We know how difficult it is to switch between applications, now all your acoustic needs are in one software.
  • You don`t have to set up another project in another software.
  • We believe working with a software should be fun and not tedious.
  • We believe our products are revolutionary.
