Who we are
Sound of Numbers
Why Sound of Numbers?
The sound can be described in many ways, from music scores to bit streams and, because of our job, we are used to see the sound as a rich field of numbers. Do not underestimate the power of numbers! When sound is portrayed as numbers it reveals many of its secrets and things which may seem impossible can be worked out. But, of course, to achieve this the language of numbers must be spoken. And we are experts in numbers!
We are a team of coders, researchers and engineers specialized in acoustic research, numerical modelling and computational geometry.
The team
Sound of Numbers is a bunch of acoustic and computer science engineers. The acoustic engineering company Sonen is a stakeholder of the company.

With SONarchitect ISO you can compute all the sound insulation values in one-third octave bands in the entire building according to ISO EN 12354:1,2,3,4,6. Results are detailed for every enclosure, separator, flank, and transmission path, and can be interactively explored..
You can identify at any time the enclosures of any floor, and tell SONarchitect the use of each room in the building. This determines the aplicable legislation limits to verify the building compliance. Room identification and use can be changed at any time, before or after the computation, without any additional hassle.
SONarchitect ISO computes the noise emission maps from any noisy room in your building, according to EN 12354-4 Annex E
Print the results you want and the way you want. SONarchitect provides a flexible report generator. Add your enterprise logo, select a cover image with the 3D model of your building, get a bill of quantities for your budget estimations, include a compliance statement, show the quality classification of your building, detail every computation result including components and transmission paths. Or none of them. You can select individual rooms or let SONarchitect select only the worst cases: Yes, indeed, you have computed the acoustic insulation in the entire building, therefore you know they really are the worst!
Get a subjective experience of the acoustic performance of your building with the auralisation engine, directly accessed from the result tree. Play one of the built-in tracks or your own recordings in any room of your choice and hear how they would sound in the adjacent rooms compared to the emitter room. You only need a good pair of headphones. Take a walk around the 3D environment and feel the differences thanks to the binaural audio processing.
