In the second part of this two-part interview, Robert Celmer, professor of mechanical engineering in the University of Hartford's College of Engineering, Technology, and Architecture, discusses the finer points of acoustical engineering. He talks about the causes of motor vehicle noise; the elements of sound:amplitude, frequency, and time; what causes some sounds to be pleasant; consonance and dissonance; digital sound encoding and compression; advances in sound reproduction; and acoustical considerations in theater design.
