Tribute to An Industry Pioneer: Gunnar Rasmussen (1925-2024)

The founder of GRAS Sound & Vibration, the renowned acoustical engineer Gunnar Rasmussen, passed away on April 17, 2024. Gunnar Rasmussen founded GRAS in 1994, at the age of 67, after leaving Brüel & Kjær, where he worked since his graduation. Starting out as a small family business, run by Gunnar Rasmussen and his wife Hanna Hertz, the Danish measurement microphones specialist quickly grew into a respected manufacturer, lead by his extraordinary vision and guiding principles. His lifework improved our understanding of sound, acoustics and the human hearing.

HEAD acoustics introduced a new and much improved design for its artificial heads paving the way for new era of communication and audio quality measurements. The new generation of artificial heads ensures a new level of realism, precision and flexibility when coupled with HEAD acoustics modular concept approach, meeting the most diverse of applications in the field of acoustic measurement technology.

The world of communication and entertainment is evolving and consumer expectations for audio quality continue to increase, and with it the requirements for improved test equipment that can accurately predict the perception of human hearing and speech. A head and torso simulator (HATS) is an objective measurement instrument with built-in, human-like ear and mouth simulators that provides a realistic reproduction of the acoustic properties of an average adult human.

Dr. Jan Rennies-Hochmuth has been awarded a grant from the “Klaus Tschira Boost Fund” for his research on personalized hearing systems for improved speech communication at the Hearing, Speech and Audio Technology Division (HSA) of the Fraunhofer Institute for Digital Media Technology IDMT in Oldenburg. Rennies-Hochmuth’s research work aims to understand better how speech is perceived in complex listening conditions and above all how information is combined across both ears.

HEAD acoustics announced open enrollment for their new series of complimentary educational voice quality web based seminars. These one hour sessions are designed to provide short but focused information on voice quality topics that are normally not taught in college level classes. Anyone interested in learning more about the fundamentals of voice quality testing is invited to attend.
