One size loudspeaker model does not fit all acoustic test requirements!


Tailored, Scalable DFAT Systems

 

While we own our own in-house manufacturing and production processes - and therefore we could easily choose to design and manufacture a single loudspeaker for DFAT - our Matthew Polk ("MP") lineup of speakers are instead purposefully designed to be separated out by frequency ranges. This results in tailored, scalable, and modular test setups that can precisely meet a target test spectrum.

 

Wait... Why Separate Transducers by Frequency Ranges? 🤔

 

A single cabinet design attempting to cover the full acoustic test spectrum can lead to inefficiencies and sub-optimal performance. Simply adding identical speaker cabinets into a bigger stack assumes consistent, uniform test conditions. However, this overlooks the varying frequency responses of different components, which may need specialized frequency emphasis.



MSI DFAT provides frequency-specific, scalable loudspeakers for DFAT.

 

Optimized Performance: Our cabinets are optimized for low, mid, high, and ultra-high frequencies, enhancing acoustic performance and test accuracy.

 

Proven Results: Specialized configurations with frequency-specific loudspeaker cabinets can result in better test outcomes, particularly in high-precision tests involving complex satellite systems and large-scale tests.

 

Efficient Inventory Management: Maintaining separated speaker design models is simple and straightforward.

 

Cost-Effectiveness: Specialized configurations can reduce costs by optimizing power usage and minimizing over-provisioning, avoiding unnecessary expenses for unneeded frequency ranges.

 

Space-Savings: A large, clunky single-cabinet design requires more space and is harder to maneuver, setup, and fit inside a room.


Acoustic experts understand the importance of separating out transducers according to their frequency ranges.


That's all for now folks!

MSI DFAT Continues to Lead in Spacecraft Acoustic Testing in Europe

MSI DFAT has a longstanding presence and a robust portfolio of customers throughout Europe, where we have become a trusted partner in spacecraft acoustic testing. As we continue our journey within the European space industry, MSI DFAT eagerly anticipates the upcoming ECSSMET conference. This year, we're proud to feature several highly technical presentations by our in-house thought leaders, as well as highlight the work of our highly esteemed partners and friends from SIEMENS DI SW, Thales and Airbus.


  • Dr. Alberto Garcia de Miguel of SIEMENS DI SW will present on "Analysis of the Vibro-Acoustic Interaction in Direct Field Acoustic Noise Tests via Optical Measurement Techniques."

  • Mr. Umberto Musella of SIEMENS DI SW will discuss "Adopting Direct Field Acoustic Noise Testing Technology for the Replication of Directional Acoustic Fields: Challenges and Results."

  • Dr. Bart Peeters of SIEMENS DI SW will present on "Using Direct-Field Acoustic Test Data for Operational Modal Analysis of the PROBA-V Satellite."

  • Mr. Christophe Fabries of Thales will discuss "Direct Field Acoustic Noise Test - Power versus Control Strategy."

  • Dr. Alessandro Carrella of MSI DFAT EU Srl will present on "Validation of Vibroacoustic Analysis of a 3D Structure with DFAT."

  • A new special paper co-authored by Umberto Musella and Alex Carrella 🤫


We look forward to sharing our latest advancements in DFAN Testing at the conference. The European Conference on Spacecraft Structures, Materials and Environmental Testing (ECSSMET) aims to foster discussion and exchange of experience within the mechanical engineering community, focusing on topics related to spacecraft structures, materials, and environmental testing.

MSI DFAT on Off-Nominal Podcast (Episode 162)


In other news... 😉


Jake and Anthony from the Of-Nominal Podcast were recently joined by Logan and Alan from MSI DFAT to talk about blasting satellites and spacecraft with sound waves.

Tune in to episode 162 (and subscribe to Off-Nominal!) https://offnom.com/episodes/162


Reflections on Small Satellite (SmallSat) Conference 2024


Last week, we wrapped up the SmallSat in Logan, Utah (...not to be confused with the other SmallSat conference in California) 😉


MSI DFAT was proud to sponsor coffee!

Since the conference has compounded in attendance year over year, SmallSat in 2025 has outgrown the town of Logan and will be held instead in Salt Lake City.


Here is the highlight reel (and why you should come out to SLC in 2025!):

That's all for now, folks! See you at ECSSMET!

...From backstage to blastoff!


...From rockstars to rockets!


...From concerts to cosmic!


MSI - DFAT SERVICES, LLC was born out of Maryland Sound International, a concert and music production company that worked with Pink Floyd, Frankie Valli, Van Halen, Whitney Houston and many other loud, live music and entertainment events.


Today, they are working on testing programs for organizations like NASA - National Aeronautics and Space Administration's Orion Crew Module for the lunar missions that are part of the Artemis program.


How did this company go from producing music to testing space payloads for launch qualification and certification?


MSI DFAT has been busy chatting with the space industry about just that... Check out the replays!
