Yu (Dewey) Du is a Senior Principal Acoustic Engineer in the Automotive Microphone, Headphone and Sensor team at Harman International – Automotive Audio Division. He developed the interest in audio engineering and hearing science ever since his first industry job out of the graduate school when he was tasked to develop advanced technology solutions for personal hearing protection and communication systems targeting at military applications in extremely loud noise environments. He has over fifteen cumulative years of experience in engineering research and development in the areas of miniature acoustic transducers, MEMS microphones and automotive microphones and sensors.
Yu received his PhD degree in Mechanical Engineering from Virginia Tech in 2003 focusing in sound and vibration control. He has authored over 30 scientific publications on acoustic transducer development, modeling as well as structural vibration, and noise control. Yu also holds multiple U.S. and International Patents related to the design and application of acoustic transducers and devices. He has been an active AES member since 2009.

Dan Field graduated from Southern Illinois University and soon took up with a southern Indiana company that was to become Harman’s automotive sound headquarters. There he developed commercial and music instrument speakers, and a number of automotive innovations, including Ford-JBL sound systems.
He later held senior technical positions at RCA during the early days of HDTV, and with Klipsch during their strong growth years. Dan returned to Harman for another 12 years in 2002 to help the company re-establish strong ties with GM, Ford, and Chrysler, introducing along the way many new premium audio systems.
He recently retired from a senior technical position with Panasonic Automotive Systems, America where he was charged with mentoring young talented engineers, and benchmarking and developing still more premium audio systems
Dan is a past board member and standards chair of ALMA, and has been an AES member since 1977.
Dr. Samira Mohamady is an acoustics expert with more than 10 years of profound industrial and academic experiences in the field of acoustic and vibro-acoustics simulation and analysis, Active Noise Control (ANC), audio signal processing and validation. She has significantly been involved in various projects and pre-development
projects at the Ingenieurgesellschaft Auto und Verkehr (IAV) in Munich, Germany and is a Scrum Master of projects with an interdisciplinary team structure. She has received her doctoral degree from Institute for Technical Acoustics (ITA) at the RWTH Aachen University, in this time she has investigated the influence of uncertainties on Transfer Path Analysis (TPA) and sound design in closed environments with consideration of deviation of psychoacoustic parameters, which can be or rather been used as a guideline for the purpose of TPA. She has also been an active member and organizer of Young Acousticians Network (YAN) of European Acoustics Association (E.A.A.) and has organized YAN event at the DAGA 2016 in Aachen, Germany.
