In Memoriam: Professor Herbert Voigt
The Scientist Who Helped the World to Hear
1949 - 2018
Introduction
The world of science is built by brilliant minds, but truly transformative impact is created by those who blend deep scientific insight with a profound commitment to human connection.
Professor Herbert Frederick Voigt III was one of these rare individuals—a visionary biomedical engineer whose pioneering work on the auditory system helped unravel the mysteries of human hearing, while his global leadership shaped the very landscape of medical and biological engineering. His sudden passing on January 25, 2018, left a void in the scientific community, but his legacy continues to resonate through the countless lives he touched, the students he mentored, and the groundbreaking research he contributed to his field 3 7 .
A Life of Leadership and Global Impact
Herbert Voigt's distinguished career was characterized by relentless curiosity and an extraordinary capacity for leadership across numerous prestigious organizations. With a BE in Electrical Engineering from the City College of New York (1974) and a Ph.D. in Biomedical Engineering from Johns Hopkins University (1980), Voigt possessed the foundational expertise that would propel him to the forefront of his field 7 . His professional home was Boston University, where he served as a Professor of Biomedical Engineering and an Associate Research Professor of Otolaryngology, passionately dedicating himself to both education and innovative research 3 .

Decoding the Mysteries of Hearing
At the heart of Voigt's scientific work was his fascination with the auditory system—specifically, the complex neural circuitry of the cochlear nucleus 3 7 . This region of the brainstem serves as the first major processing center for auditory information coming from the ear, and understanding its intricate wiring is crucial to comprehending how we perceive and interpret sounds.
Voigt co-authored the "Auditory System" chapter in the prestigious "Biomedical Engineering Handbook," which has become a foundational resource in the field 6 . His contribution provided a comprehensive overview of the system, from the peripheral auditory system that captures sound waves to the central auditory system that processes this information in the brain 6 . The chapter also addressed various auditory pathologies, connecting fundamental research to clinical applications that could improve human health 6 .
His research approached hearing not merely as a mechanical process but as a sophisticated neurocomputational challenge. He investigated how the brain distinguishes between different sound frequencies, locates sound sources in space, and separates meaningful signals from background noise—functions that are essential for human communication but often prove challenging for individuals with hearing impairments.

Inside a Pioneering Auditory Experiment
Methodology: Mapping the Neural Pathways
One of Voigt's most significant research contributions was his experimental work mapping the neural circuitry within the cochlear nucleus. The methodology his team employed represents a classic yet sophisticated approach in neurophysiology:
Experimental Process
- Animal Preparation: Anesthesia administration and stereotaxic positioning
- Surgical Exposure: Craniotomy to access the cochlear nucleus
- Acoustic Stimulation: Precisely calibrated sound delivery
- Neural Recording: Extracellular recordings with microelectrodes
- Data Analysis: Response pattern characterization
Results: Neural Response Patterns
| Cell Type | Response Pattern | Function |
|---|---|---|
| Primary Cells | Sustained firing | Transmission of sound timing |
| Chopper Cells | Regular, periodic firing | Sound pattern analysis |
| Pauser/Buildup Cells | Delayed response | Complex feature processing |
The experimental results demonstrated that the cochlear nucleus is not merely a passive relay station but an active processing center where specific neural circuits extract distinct features from auditory stimuli 6 . This foundational work has profound implications for developing better cochlear implants and other neural prostheses that can more naturally replicate the brain's own sound processing mechanisms.
