| 內容簡介 | This technical book helps the design engineer and acoustician to understand the noise development of machines and systems in a comprehensible way, based on an acoustic weak point analysis. It is essential to distinguish between airborne and structure-borne sound radiation. This knowledge enables the designer to develop targeted primary and secondary noise reduction measures. Selected application examples from practice support the user in developing his own ideas for the implementation of product-related noise reduction. The content - Physical principles of the generation, transmission and radiation of machine noise - Mechanisms of noise generation - Measurement techniques - Various noise reduction options for primary and secondary measures - Field-tested application examples The target groups - Engineers, plant designers and acousticians involved in primary, secondary and design noise abatement. - Students of mechanical engineering, process engineering and technical physics at technical colleges, universities and universities of applied sciences. The author Professor Dr.-Ing. Gh. Reza Sinambari taught, among other things, the subjects of sound and vibration protection, emission technology acoustics and construction acoustics at the FH Bingen. He was managing director of the company IBS, Ingenieurbüro für Schall- und Schwingungstechnik GmbH, Frankenthal, for approx. 27 years, where he currently works as a consultant. This book is a translation of an original German edition. The translation was done with the help of artificial intelligence (machine translation by the service DeepL.com) A subsequent human revision was done primarily in terms of content, so that the book will read stylistically differently from a conventional translation. |
