摘要
随着舰艇隐身技术的发展,由舱室空气噪声引起水下噪声变得越来越重要。本文从经典的声波透射理论出发,建立了一种较简单的空气噪声传递产生水下噪声的工程估算方法,其中壳板的声压透射系数采用混响声场中各种角度无规入射的平均透射系数。通过与实船测试结果进行比较,基本上验证了此方法的实用性。
As the improvement of the naval ships stealth,the underwater noise induced by the airborne transmission become more important. A simple engineering estimation method derived from classical sound transmission theory was established.The transmission of the hull is described by the average transmission coefficient of random incident sound in a reverberant acoustic field. The method was basically validated by the comparison with the experimental results of a naval ship.
