Signal To Noise Podcast

In Episode 279, the hosts learn all about Direct Field Audio Testing, or as one of this week’s guests put it, “Blasting super loud sound at spacecraft and satellites!” This episode is sponsored by Allen & Heath and RCF.Many listeners will be familiar with Maryland Sound International (MSI), the sound company best known for its work on large-scale events like New Year’s Eve in Times Square, the U.S. Presidential Inauguration, and many more. Fewer know of their sister company, Maryland Sound International — Direct Field Audio Testing (MSI-DFAT), which specializes in turning touring and sound reproduction expertise into creating portable, on-demand acoustic testing labs for spaceships, satellites, and other aerospace devices, replacing much more expensive reverberant chamber facility-based testing. If you thought concert PA systems were loud, wait until you hear about pummeling spaceships with 150-plus dB SPL levels to make sure they’re safe for launch and orbit!Guest Alessandro “Alex” Carrella, VP Strategy & Growth at MSI-DFAT, has a degree in Aerospace Engineering from the University of Naples (Italy) and was awarded a PhD in Structural Dynamics at the ISVR (University of Southampton, UK). He’s now completing his EMBA at the Universite Louvain-la-Neuve. Alex was a lecturer in Structural Dynamic at the Dept of Aerospace at the University of Bristol. From 2011 to 2020 he worked in different roles to develop testing solutions for the aerospace industry at Siemens (formerly LMS) in Leuven (Belgium). He has become a referent point for the space industry for vibration and acoustic testing, and has been a leading figure in advancing DFAT practices is an active member of the space testing community. Alex has joined MSI-DFAT to lead its international operations and is now shaping MSI’s future as VP for Strategy & Growth.Guest Bradley Hope, U.S. Business Development Manager at MSI-DFAT, holds a wealth of experience in acoustic and vibration test engineering and enterprise-level customer relationship management, within the global aerospace industry. Trained under the guidance of vibro-acoustic specialists at Siemens Digital Industries Software, coupled with his passion for business and intrapreneurship, Bradley brings deep commercial expertise to the MSI-DFAT team. Having collaborated closely with clients on a range of complex projects across PLM, CAD, CAE Simulation, and Test Engineering, he possesses a strong understanding of the unique requirements and consistent evolution of the space, aircraft and defense industries. Bradley is enthusiastic about supporting the customer-partners of the Maryland Sound International-Direct Field Acoustic Test (MSI-DFAT) company in its Direct Field Acoustic Noise testing campaigns.Episode Links:MSI-DFAT | Direct Field Acoustic TestingMSI-DFAT on Instagram“NASA’s Successful Quantifying of Comedy Timing” by Penn Jillette and TellerEpisode 279 TranscriptConnect with the community on the Signal To Noise Facebook Group and Discord Server.
