During his scientific career, Dr. D’Antonio published widely and was a member of the internationally renowned Laboratory for the Structure of Matter, headed by Nobel Laureate Dr. Jerome Karle. As a musician and recording engineer, Dr. D’Antonio maintained a separate concurrent career in the music industry.  In 1974, he developed a widely-used design for modern recording studios at Underground Sound, Largo, Maryland, utilizing a temporal and spatial reflection-free zone and reflection phase grating diffusors.  Dr. D’Antonio Founded RPG Diffusor Systems, Inc., in 1983 to develop and test novel surfaces to expand the acoustical palette. After more than three decades of successful innovation and operation, he sold RPG in 2017. The company was relocated and restructured as RPG Acoustical Systems, LLC. Dr. D’Antonio is currently Director of Research at the new company and Director of the new Acoustical Research Center. To return to his initial musical interest in critical listening room design, he joined the staff of REDI Acoustics, LLC, as Director of Research.

He pioneered the sound diffusion industry and has significantly expanded the acoustical palette by creating and implementing a wide range of novel number-theoretic, fractal, and optimized diffusing and absorbing surfaces, for which he holds many trademarks and patents. He has lectured extensively, published numerous scientific articles in peer review technical journals, acoustical and architectural magazines and is the co-author of the reference textbook Acoustic Absorbers and Diffusers: Theory, Design and Application, 3rdEdition published by CRC Press (August 2016). He has also contributed several chapters to the Master Handbook of Acoustics, 6thEdition published by McGraw Hill Professional 2015 and a book that reflects the life, work, and legacy of one of the greatest acousticians of the 20th century entitled Acoustics, Information, and Communication: Memorial Volume in Honor of Manfred R. Schroeder, published by Springer and edited by Ning Xiang and Gerhard M. Sessler (2015). A complete list of Dr. D’Antonio’s publications can be found on Google Scholar. 

He served as Chairman of the AES Subcommittee on Acoustics Working Group SC-04-02, which published AES-4id-2001 for diffusion coefficient standardization; is a member of the ISO/TC 43/SC 2/WG25 Working Group, which published ISO standard 17497-1:2004 for scattering coefficient standardization and ISO 17497-2 for diffusion coefficient standardization. Dr. D’Antonio has also served as adjunct professor of acoustics at the Cleveland Institute of Music, since 1991.  He is a Fellow of the Acoustical Society of America and the Audio Engineering Society and a 2012 Inductee into the music industry’s TECnology Hall of Fame.  Currently, Dr. D’Antonio is also President/Founder of the Chesapeake Acoustic Research Institute, LLC (CARI), founded in 2007, and Director of Research at RPG Acoustical Systems, LLC and REDI Acoustics, LLC

Rinaldi Petrolli was born in 1994 in Porto Alegre, the capital of the southernmost state in Brazil, Rio Grande do Sul. In 2019, he received a B.S. degree in Acoustic Engineering from the Federal University of Santa Maria. Since a young age, he has been a music lover with a great passion for musical instruments and the intricacies of their inner workings. He started to learn to play the guitar at age nine, and the love for instruments and music led him to a luthier apprenticeship for two years at age fifteen, working with his music teacher in instrument repair and maintenance. How sound works and why it changes from instrument to instrument was always a source of significant curiosity to him, which led him to the path of studying acoustical engineering to further expand his knowledge about sound.

While at university, he studied subjects such as room acoustics, digital signal processing, electroacoustics, environmental acoustics, psychoacoustics, building acoustics, acoustic measurements, computer programming, and many more. In parallel to that, he developed programming skills in MATLAB and Python by implementing measurement and post-processing routines used to perform all experiments throughout his studies. His undergraduate thesis researched a low-cost method for modeling tube amplifiers, which was successfully done with Machine Learning and Long Short-Term Memory neural networks, enabling real-time emulation through a Python interface. He is also a collaborator for PyTTa – Python in Technical Acoustics, an open-source library that allows the user to make and evaluate acoustic measurements within a Python framework. 

In 2018, he joined WSDG first as an intern and then as an engineer, collaborating in research, development and different aspects of acoustical analysis and simulation, mainly focused on numerical methods. After meeting Peter D’Antonio while working with WSDG, Rinaldi joined REDI Acoustics, LLC to continue research and development, focusing on Python implementations of boundary element method applications for low-frequency analysis and optimization and performance evaluation of acoustic devices. Along with that, he also performs acoustic analysis using advanced techniques,  diffusive devices placement and modulation in small rooms, and several comparisons between acoustic predictions and real-world measurements.

Thiago was born in 1996 in Araçatuba, a small city in the countryside of São Paulo state, Brazil. In 2014 he started attending an Acoustic Engineering course at the Federal University of Santa Maria, Brazil, and he is going to receive his B.S. degree by October 2020. Since he was 10 years old, Thiago started attending drums classes and playing at church, which he does until today. His love for music and his facilities with math calculations led him to join both things and attend the acoustic engineering course.

While at university, he studied subjects such as room acoustics, digital signal processing, electroacoustics, environmental acoustics, psychoacoustics, building acoustics, acoustic measurements, computer programming, and many more. His undergraduate thesis is about wind turbines, where he built a simple prototype and measured it, based on the IEC 61400-11 Standard. Also, he made measurements using the beamforming technic, to find noise points in the prototype.  

In January 2020 Thiago started his internship at WSDG and in June he joined the REDI Acoustics team, helping with NIRO simulations and reports, as well as helping the WSDG Highland office team with advanced models and Sabine and Eyring calculations. 

 Artur Zorzo was born in 1994 in Brasília, Brazil. In 2012, in an effort to make better recordings of his band, he completed a professional audio course and instantly fell in love with acoustics after a lecture on the subject. In 2018, he received a B.S in Acoustic Engineering from the Federal University of Santa Maria.

He published several papers while in university. Most of them in the areas of real-time audio signal processing and acoustic measurements. For his undergraduate thesis, he researched and developed an active noise control system for headphones using real-time adaptive digital filters. In 2018, for his internship, he worked on the geometrical and acoustical optimization of ambisonic microphones. 

From 2019 to the beginning of 2021 he worked at Devialet as a signal processing R&D engineer in the development of signal processing algorithms for active noise-canceling earbuds. A patent was filed based on his works on the Ear Active Matching (EAM) algorithm. The EAM system automatically tunes the signal of the music to the shape of an individual’s inner ear. In parallel to that, he worked on the acoustic implementation of MEMS microphones on the products.
