Cost Effectiveness of Alternative Noise Reduction Methods for Construction of Family Housing.

摘要

The objective of this work was to obtain the cost/benefit relationships associated with new, quieter construction equipment and/or construction process modification. A workable cost/benefit model was developed for this purpose, but a significantly larger data base must be acquired to apply this model. This initial work effort concentrated on one type of construction-multifamily housing construction. Significant findings included: (1) Construction site boundary noise can be significantly reduced by a number of currently available techniques; (2) the use of two quieter machines of lower capacity in lieu of one standard machine not only costs more but is of questionable noise control value, since the total noise exposure is sometimes greater from two machines than from one larger machine; (3) cost/benefit relationships for estimating purposes can be provided only after a significantly larger data base is obtained.
