The earlier virtual processes are used in the product development process, the greater the benefits for product development. Various design and engineering phases are characterized by testing, evaluation, optimization and testing. The use of modern virtual methods helps to simulate complex systems and to identify shortcomings quickly. MVOID helps to optimize products with acoustic properties and changes the development of products. What is behind the technology? Business case examples and economic benefits of MVOID technology can be found in the following overview:

What is the MVOID simulation process methodology?

MVOID analyzes, evaluates and optimizes products with acoustical properties in the virtual space by multidisciplinary simulation. It represents a fully digital development environment for automotive audio systems and integrates the following engineering disciplines:

  • Multiphysical engineering analysis
  • Sound tuning
  • Auralization
  • Digital signal processing
  • Psychoacoustics
  • Subjective evaluation

MVOID has developed a methodology that makes it possible to transfer the first ideas of pre-development of acoustics and sound design by a multidisciplinary simulation model to the real world. Thanks to auralization it is made audible – even before the first prototype is built, and provides the basis for the landmark decision for further development.

Reduce development time while at the same time product quality is being optimized
The main advantage of the MVOID methodology is to reduce development time while improving product quality, as the MVOID methodology significantly reduces long-lasting tests on prototypes. In the past, disturbing acoustic influences had to be adjusted respectively eliminated by acoustic experts manually on physical prototypes while today they are quickly recognized and optimized in the virtual space. By using MVOID in the pre-development phase completely new ways of packaging and integration can be considered: e.g. the use of cavities of the vehicle structure as resonance volumes for loudspeakers.

How is the business case defined?
There are couple of approaches to the business case depending on the actual phase of the development cycle. As follows you will find the most common business cases:

Evaluation in Pre-Development
At a very early stage of development (concept phase or platform development), when only a few parameters are known, the MVOID technology transfers ideas into reality and explores new solutions. During this phase, there are lots of uncertainties with basic constraints on the designed space. Not much details are known – hence it is not possible to build a physical prototype. Well, how to evaluate the concept then? Up to now this was based on experience and intuition with vague results. With the MVOID technology even at this stage the results are clear and lead to well-founded decisions, resulting in superior concepts and design proposals.

Evaluation of the Acoustic Concept – Feasibility Studies
At some point the concept must be evaluated. So far this was done by means of early stage physical prototypes. However, these first prototypes still include lots of uncertainties (e.g. with respect to materials, as rapid prototyping parts are used, but also with respect to general progress on ongoing design work) with little to no benefit for conclusions on the expected sound quality. There is no advantage of the physical prototype compared to the MVOID based virtual prototype. Hence, we can skip the physical prototype, and save significant costs. Additional to cost savings, already at this stage the quality is improved, and speed and efficiency of development is significantly increased. 

The business case for the investment in MVOID methodology is thus clearly defined. The break-even point is reached on the very first use. The investment has a payback, as MVOID does not require any physical prototype for concept validation. 

Evaluation of the Acoustic Concept in Detail Engineering  
In the beginning of detail design work for series development, it is still challenging to manufacture physical porotypes due to the high dynamics in progress of work. Virtual models are needed to quickly answer questions leading to the right decisions. At least in the early phase yet another physical prototype can be skipped, resulting again in significant cost savings, and the ROI can be well defined.

The advantages of multidisciplinary development of automotive audio systems using MVOID methodology are obvious from our point of view: The virtual development of the systems in the computer allows to analyze, evaluate and optimize concept ideas and different levels of technical development without building physical models or prototypes. Inadequacies and errors can be discovered at an early stage, before they will cause additional costs in later stages of the development or even production process and will result in dead time. Development time can thus be significantly shortened, costs can be saved, and the quality can be improved. Within a short time, the business case has a break even reached by investing in the MVOID methodology.
