Abstract:

Paul Veneklasen's interest in acoustics was wide ranging. Research and development in electroacoustics occupied his endeavors in the early years. This paper will present a survey of his work. Topics to be presented include development of a series of condenser microphones and loud- speaker systems at the Altec Lansing Corporation, and development of instrumentation to measure the sound pressure level using Western Electric 640 AA condenser microphone. Projects of a more unusual nature included the development of a Fabric Acoustimeter or ``Fuzz Feeler'' to measure by acoustic means the ``handle'' of a fabric development of the tooth and forehead microphones for detecting and transmitting voice signals in very high-level noise enviroments and research and development of the electronic stethoscope. This instrument extended the frequency range of heart sound analysis. Paul's interest and pioneering work in auditorium acoustics led to contributions to the development of instrumentation for use in acoustical scale modeling research.
