This classic and authoritative textbook contains material that is not over-simplified and can be used to solve real-world noise control engineering problems. It covers the principles with practical application of current noise control technology.Topics new or revised from the 5th edition include: beating; addition and subtraction of noise levels; combining multi-path noise level reductions; hearing damage assessment and protection; speech intelligibility; noise weighting curves; instrumentation, including MEMS, IEPE and TEDS sensors; noise source types, including transportation noise and equipment noise estimations; outdoor sound propagation, including noise barriers, meteorological effects and sloping ground effects; sound in rooms, muffling devices, including 4-pole analysis, self noise and pressure drop calculations; sound transmission through single, double and triple partitions; vibration measurement and control, finite element analysis; boundary element methods; and statistical energy analysis.Covers all aspects of industrial and environmental noise controlCore advanced undergraduate and graduate textbook; and reference text for acoustic consultants and engineersPractical applications demonstrate the theoretical conceptsA wide range of example problems and solutions that are linked to noise control practice are available for download from www.causalsystems.com.
