Controlling Ventilation Noises


Book Description







A Practical Guide to Noise and Vibration Control for HVAC Systems


Book Description

This major revision of the previously published 1991 version provides information for engineers, architects, contractors and other building industry professionals who have little or no experience with acoustical terms or concepts. Presents practical design guidelines to help minimize the possibility of excessive HVAC system noise and vibration in and around buildings, and by suggesting investigation methods to help solve existing noise and vibration problems. ASHRAE Research Project 526.




Prediction and Control of Noise and Vibration from Ventilation Systems


Book Description

This book addresses the prediction and control of noise and vibration in ventilation systems and their psychoacoustic effects on people. The content is based on the authors’ research and lecture material on building acoustics and provides insights into the development of prediction methods and control of noise and vibration from ventilation systems, and an assessment of their psychological effects on people. The basic principles and methods for prediction and control of noise and vibration from ventilation systems are discussed, including the latest developments on flow-generated noise prediction, assessment methods for the performance of vibration isolation, noise control using periodic Helmholtz Resonators, and holistic psychoacoustic assessment of noise from ventilation systems. The insightful book on noise and vibration in ventilation systems Extends into prediction, control, and psychoacoustic assessment methods The book suits graduate students and engineers in acoustics and noise and vibration control, as well as in building services engineering and across the built environment.




Quieting


Book Description







Quieting: A Practical Guide to Noise Control


Book Description

This guide offers practical solutions for ordinary noise problems that a person is likely to meet. The book describes the ways in which sounds are generated, travel to the listener, and affect his hearing and well-being. Recommendations are given for controlling noise at the source and along its path of travel, and for protecting the listener. This guide instructs the reader by way of "Warning Sings" on how to determine whether he is being subjected in his environment to prolonged noise exposures that may prove hazardous to his hearing.Remedies are given for noise problems that a person is likely to find in his home, at work and at school, while traveling, and in the growth and development of his community. The remedies include noise prevention techniques and selection of quiet alternatives to existing noise sources. General principles for selecting quiet appliances are given. Ways of searching for the sources of noise and for determining the paths over which they travel to the listener are described. A detailed index is given for individual ways of looking for inherently quiet homes and travel accomodations are described.In a final chapter, there are suggestions for enlisting community help where large external sources of noise must be quieted, such as those arisseing from public utilities and public transportation.
