Sound and Vibration Studies
Environmental sound and vibration can originate either from internal mechanical equipments or from a variety of outside sources such as transformers, vehicles, cooling towers, fans, motor-driven equipment, and a host of industrial machinery and processes. In addition to disturbing people, sound and vibration also can adversely impact certain types of processing equipment. For example, while humans can detect floor vibration exceeding a Root Mean Square (RMS) velocity of approximately 125 microns per second, certain equipment exhibits vibration-related malfunction if floor vibration exceeds 6.25 microns per second. Moreover, noise transmission is affected by three major environmental influences: distance, atmospheric conditions, and terrain/vegetation. When existing environmental sound and vibration adversely influence the success of a project, Cliff Sroka Sound and Vibration perform Environmental Sound and Vibration studies to evaluate the impact of these factors prior to construction. A complete Environmental Sound and Vibration Study contain the following three elements. When a comprehensive study is not required, we will perform any of the elements of a complete Environmental Sound and Vibration Study individually.
Noise Prediction Study
Traffic noise calculations account for traffic flow patterns, speed limits, terrain, distance from the road, and the car/truck ratio. Equipment noise is either measured or estimated, based on known sources for a specific type of equipment. Cliff Sroka Sound and Vibration predicts sound levels from environmental sources, such as outdoor equipment and traffic. We then evaluate the predicted sound levels for compatibility with the proposed use and for compliance with all existing land use restrictions and federal, state and local regulations. Where required, we also make recommendations for noise attenuation.
Ambient Noise Study
To establish the ambient noise levels for a proposed project, Cliff Sroka Sound and Vibration measures and assesses the existing noise levels, comparing them with applicable land use restrictions and federal, state, and local noise regulations. Based on these analyses, Cliff Sroka Sound and Vibration predicts how ambient conditions will affect the proposed project. We also recommend methods for reducing noise levels to comply with all pertinent regulations.
Excessive noise can seriously diminish the quality of life in neighbourhoods and communities. Cliff Sroka Sound and Vibration measures, analyzes, and compares the impact of emitted sound against applicable state and local regulations. Where violations occur, we recommend strategies for limiting noise emissions. Cliff Sroka Sound and Vibration also perform follow-up studies to ensure the desired results are attained.
