Abstract:

Early in the authors careers working with Paul Veneklasen at the Western Electro-Acoustic Laboratory, the authors were involved with programs dealing with speech communication in high-noise fields and the development of a new ear plug, possibly to replace the venerable V51-R ear defender that was developed by Paul Veneklasen, Vern O. Knudsen, and others during World War II. His later interests were involved with the perception of lateral reflections in rooms, which Knudsen called ``envelopment,'' primarily through research in his patented Auditorium Synthesis demonstration room. Highlights of this work are recounted including the novel forehead, ear, and tooth microphones.
