Abstract : The study on Shipboard Noise Criteria is primarily concerned with the contractual viability of single-number metric standards for shipboard equipment and spaces. As an initial step toward providing transition guidelines from octave band to dBA standards, Andrulis Research Corporation (ARC) has devised a methodology based on statistical considerations for the classification of equipment and of spaces in terms of single-number metrics. Implementation of the ARC scheme should not only clarify the feasibility of classifying frequency-dependent equipment and spaces in terms of single-number metrics, and of predetermining layout designs and noise control procedures, but also the practicability of the currently proposed dBA levels.
