A mechanism study of sound wave-trapping barriers.
The performance of a sound barrier is usually degraded if a large reflecting surface is placed on the source side. A wave-trapping barrier (WTB), with its inner surface covered by wedge-shaped structures, has been proposed to confine waves within the area between the barrier and the reflecting surface, and thus improve the performance. In this paper, the deterioration in performance of a conven...

This paper was initially presented at the CEDA Dredging Days in November 2015 and was included in the conference proceedings. It is reprinted here in an adapted version with permission. Underwater sound from anthropogenic sources and its potential adverse effects on the marine environment is a topic of much global interest. In recent years, there is recognition that sound from some shipping and...

متن کاملData Dredging
Suppose there is a given data set and there are a huge number of hypotheses [1] about this data set [2]. If the data is totally random, then say all the hypotheses are actually false. However, owing to the sheer number of hypotheses on a limited data set, it is possible to see some very highly correlated [3] data that are statistically significant [4]. In such cases, data dredging is said to ha...
