Mvoid Technologies Expands Methodology for Acoustical Virtual Product Development

June 18 2020, 00:40
Mvoid Technologies GmbH, the German company specializing in virtual audio product development, has released the latest Mvoid Methodology version 2.3. Mvoid Acoustical Virtual Product Development methods use a combination of standard modeling, simulation and measurement software, combined with virtual reality and 3D visualization and binaural auralization tools for Automotive, and Professional Audio applications. 

According to Mvoid, the new version adds process level six to the Mvoid-Auto and Professional Audio product range. This process level enables the measurement of physical audio products and is a key element for the creation of digital twins - which enable instant comparison between different approaches or designs. Many additional functions are introduced in the new release, providing enhanced accuracy, increase usability and allowing a closer coupling of all functions.

Mvoid is a pioneer and expert in virtual acoustics with the focus on simulation of all hardware in the audio chain. The company guides manufacturers and R&D departments in Automotive, Professional and Consumer Audio Virtual Product Development, a process that uses advanced multiphysics simulations and combines modeling of all aspects of an audio system, culminating in real-time auralizations that allow actual listening evaluation and validation of design decisions.

With the new extension of its product range by process level 6, now introducing measurements of audio systems, Mvoid adds a new level of design and system validation. The Mvoid methodology for tier level six focusses on measurements of physical audio prototypes and products using a multi-channel acoustic measurement system fully integrated into VRtool, the company's own virtual tuning and auralization solution where acoustic results can be auditioned over headphones. With this combined approach, Mvoid guarantees a smooth transition from virtual prototypes to physical prototypes, including allowing for the creation of a digital twin of an audio system for direct evaluation. 

This new Mvoid measurement method defines a robust, repeatable process that provides accurate, detailed insight into mechanical and performance characteristics of audio components and systems, including in-situ room acoustic interaction. Critical to understanding manufacturing and assembly execution of design, the Mvoid tier level six measurement process converges the implementation of Virtual Product Development into real audio products through a robust validation process. For example, the manufacturing variance can be monitored and, if necessary, adopted to minimize the production variance from a reference target, or performance variances in product series.

Optimizations and additional functions available in release 2.3 of Mvoid's process levels 1 to 5 allow the generation and export of balloon plots in process levels three and four for improved visualization of the directional characteristic. The method displays the sound pressure level or radiated sound power on the surface in spherical form in color.

Ray tracing methods with advanced source modeling provide even more accurate room acoustics, and the newly integrated open source format CF2 allows a directional resolution of 5 degrees and frequency bands of 1/3 octave. Sources can be defined more precisely (spatial and frequency domain).
For automated simulation results, the automatic post-processing feature calculates the sound power over frequency for a specific or all selected locations. At the push of a button, acoustics experts can receive an evaluation of the sound or frequency at a specific point.
