Marshall Day Acoustics and Sennheiser announce collaboration

Integration of AMBEO VR Mic with IRIS room acoustics measurement system

Aachen, 9 September 2019 – At the 2019 International Congress on Acoustics, Marshall Day Acoustics (MDA) and Sennheiser have announced a collaboration to ensure that the IRIS room acoustics measurement system from MDA will now fully support Sennheiser’s AMBEO VR Mic.

“We are really thrilled to have Marshall Day Acoustics join our ‘AMBEO for VR’ partnership program,” said Véronique Larcher, Director AMBEO Immersive Audio at Sennheiser. “Moreover, it’s great to be entering the field of room measurement with the AMBEO VR Mic, an Ambisonics microphone.”

​“IRIS is among the premier room acoustics measurement systems in the world and one of the few that enables full spatial analysis, which is such a critical part of room evaluation,” commented Daniel Protheroe of Marshall Day Acoustics. “We are very happy to now be able to offer our customers direct support for the Sennheiser AMBEO VR Mic through the inclusion of the AMBEO A-format to B-format converter.”

Measuring a room’s impulse response
​The IRIS measurement system utilises an Ambisonics microphone such as the AMBEO VR Mic, which is placed at a listening position. A loudspeaker at a source position creates a single-sweep sine stimulus to excite the room, allowing the IRIS software to record the room’s impulse response in 3D and immediately process the results. IRIS intuitively visualises how the room’s surfaces reflect sound to the listening position in three dimensions, all via an easy-to-use interface. The 3D image plot created by IRIS can be used to relate sound rays to physical features of the room, observe the directional distribution of early and late sound energy, as well as identify surfaces causing problematic reflections.

In addition to the core measurement and visualisation functionality, IRIS allows users to export 3D impulse responses, which can in turn be used for rendering recorded spaces into virtual and augmented reality environments.
