The Future of Computing: Optical Computers, Bio Digital Twins & The Evolution of AI - Kazu Gomi

Send us Fan Mail [https://www.buzzsprout.com/2401252/fan_mail/new] What happens when you give the world’s leading scientists the freedom to research whatever they want? You get NTT Research, a global powerhouse operating at the edge of what’s possible in physics, medicine, and AI. In this episode of the SCL Podcast, filmed inside the MD Acoustics anechoic chamber in Gilbert, Arizona, we sit down with Kazu Gomi, CEO of NTT Research. Kazu pulls back the curtain on how a company with over 300,000 employees is tackling the massive energy crisis facing modern data centers and why the future of computing might not be silicon, but light. IN THIS EPISODE, WE DISCUSS: * The Energy Crisis of AI: Why GPUs require so much power and how NTT is aiming to reduce energy requirements by 1/10th or even 1/100th through optical computing. * The Bio Digital Twin: A revolutionary look at how digital "twins" of the human heart are being used to predict disease and automate medical treatments like "autonomous driving" for drug infusions. * Can AI Feel? New research into the "granularity" of AI emotions and how modern models are beginning to understand feelings with the sophistication of an adult human. * Attribute-Based Cryptography: Moving beyond "all or nothing" security to create files where different keys unlock specific pages or sections. * Leadership & The "Strong Core": Kazu shares his journey from electrical engineer to CEO and his advice for young professionals on perfecting their "major" to reach the next level. CHAPTERS: * 00:00 – Intro: The Anechoic Chamber  * 06:27 – The Scale of NTT: 300,000 Employees & Underwater Cables  * 10:47 – A Unique Approach to R&D  * 13:04 – Optical Computing vs. The Power Crisis  * 22:50 – Heart Health & Bio Digital Twins  * 29:22 – Next-Gen Cryptography  * 33:18 – AI’s Understanding of Human Feelings  * 41:03 – Career Advice: Finding Your Strong Core

Raising the Bar: The New Acoustical Standards Badging Program with Jeff Fullerton & Matthew Golden

Send us Fan Mail [https://www.buzzsprout.com/2401252/fan_mail/new] In this episode of the Sound Cave Labs Podcast, recorded inside MD Acoustics’ anechoic chamber, we sit down with two respected voices shaping the future of acoustical standards: Jeff Fullerton (Stantec) and Matthew Golden (Intertek). Jeff and Matt bring decades of experience in architectural acoustics, product development, vibration control, and standards committee leadership. Together, they unpack one of the biggest steps forward in the industry—the launch of the INCE Technical Badge Program, a new credential designed to improve measurement quality, unify testing practices, and help practitioners demonstrate real mastery of the standards they use every day. We explore why interpreting ASTM and ANSI standards can be so challenging, how inconsistencies develop, and what it actually takes to write and update these documents. Jeff and Matt also share stories from years of field work and committee involvement, illustrating why hands-on measurement skill is just as important as deep technical knowledge. From airborne and impact testing to outdoor measurement protocols, this conversation highlights the need for clearer, more consistent training—especially as measurement demands increase and testing becomes more central to legal disputes, design decisions, and environmental compliance. Whether you're an acoustical consultant, testing lab, manufacturer, or emerging professional looking to sharpen your skills, this episode offers valuable insight into where the industry is heading and how this new badging program can elevate both practice and accountability across the field.

From decoding speech to fighting deepfakes, Dr. Visar Berisha bridges the worlds of science, entrepreneurship, and innovation.

Send us Fan Mail [https://www.buzzsprout.com/2401252/fan_mail/new] From decoding speech to fighting deepfakes, Dr. Visar Berisha bridges the worlds of science, entrepreneurship, and innovation. In this episode of the Sound Cave Labs Podcast, Visar shares how a college speech processing project led him to pursue a PhD in speech acoustics, research at MIT Lincoln Labs, and a career spanning academia, startups, and entrepreneurship. As co-founder of Aural Analytics, he pioneered the use of speech as a biomarker for neurological conditions like Parkinson’s, ALS, Alzheimer’s, and depression, securing SBIR and NIH funding before exiting through acquisition in 2020. We also dive into his current role as Associate Dean of Research Commercialization at ASU, where he helps faculty and students translate research into real-world impact. Visar discusses the challenges of bridging academia and entrepreneurship, the importance of identifying problems people care about, and his recent witness sensing research to combat AI-generated deepfakes with radar-based verification. Packed with insights on STEM careers, innovation, and ethical AI, this episode shows how curiosity and persistence can turn academic research into groundbreaking real-world solutions. 🔗 Learn more about Visar’s work: https://visarberisha.github.io/  🔗 Follow Sound Cave Labs: https://soundcavelabs.com/

From pulling wire to leading a global AV company, Jeremy Elsesser’s story is one of growth, resilience, and vision.

Send us Fan Mail [https://www.buzzsprout.com/2401252/fan_mail/new] In this episode of the Sound Cave Labs Podcast, Jeremy shares how he went from working as a commercial electrician and network engineer to joining Level 3 Audiovisual in its early days — helping grow the firm from fewer than 10 employees to more than 120 worldwide. Now CEO, he reflects on leadership lessons, implementing EOS for organizational structure, and navigating recessions and global expansion. We discuss the AV/IT convergence, why AV lacks formal training programs, and how trade groups like AVIXA are shaping the industry. Jeremy also explains how COVID-19 accelerated AV adoption, why user interface design matters as much as engineering, and what the future holds with AI, software-defined solutions, and cybersecurity risks. Whether you’re a student, engineer, or business leader, Jeremy’s story offers insights into leadership, mentorship, and the evolving role of technology in how we connect and collaborate. 🔗 Learn more about Level 3 Audiovisual: https://level3av.com/ 🔗 Follow Sound Cave Labs: https://soundcavelabs.com/
