It could be different surface scattering, but another possibility is sub-bottom scattering which the PI has .

Artificial reverberation. Artificial reverberation is widely used to improve the sound of recordings, but has a wide range of other musical applications [DJ85, pp]. Reverberation in real, natural spaces arises from a complicated pattern of sound reflections off the walls and other objects that define the space. Reverberation likes.

The papers in this volume are grouped into 8 sections, usually in the same order as presented at the corresponding session of the Symposium: Section 1 - Scattering Mechanisms Section 2 - High Frequency Measurements and Mechanisms Section 3 - Reverberation Modelling Section 4 - ARSRP Mid-Atlantic Ridge Experiment Section 5 - Low Frequency.

The Atlantic Ocean is the second largest of the world's oceans, with an area of aboutsquare kilometers (41, square miles). It covers approximately 20 percent of Earth's surface and about 29 percent of its water surface area. It separates the "Old World" from the "New World".The Atlantic Ocean occupies an elongated, S-shaped basin extending longitudinally between Europe and Basin countries: List of countries, ports.

Measurements of the levels of bottom scattering strength have been made at a frequency of 2 kHz for grazing angles between 5° and 40° in the NE Atlantic and Mediterranean and lie in the range from −16 to −35 dB.

The scattering strength was observed to rise with grazing angle from 5° to 30° and fall again from 30° to 40°. A simple model was fitted to the data which explained the peak Cited by: 6.

Shallow water bottom reverberation results collected with a hull-mounted sonar exhibit coherence effects that manifest themselves as reverberation patterns in time—analogous to the well-known Lloyd mirror effect that appears in transmission loss as a function of range for shallow sources or receivers.

Acoustics - Acoustics - Reverberation time: Although architectural acoustics has been an integral part of the design of structures for at least 2, years, the subject was only placed on a firm scientific basis at the beginning of the 20th century by Wallace Sabine.

Sabine pointed out that the most important quantity in determining the acoustic suitability of a room for a particular use is.

Continental shelves in the Atlantic are wide off Newfoundland, southern-most South America, and north-eastern Europe. In the western Atlantic carbonate platforms dominate large areas, for example the Blake Plateau and Bermuda Atlantic is surrounded by passive margins except at a few locations where active margins form deep trenches: the Puerto Rico Trench (8, m or 27, ft maximum.

Beamformed RL data are categorized to facilitate studies emphasizing physical mechanisms of 1) bottom reverberation; 2) sea surface impact; and 3) biological impact. This paper is an overview of RL over the entire sea trial, intending to summarize major observations and provide both a road map and suitable data sets for follow-up efforts on.

We consider the results of instrumental investigations of specific features of reverberation in the Black Sea and obtain qualitative dependences of the duration of volume reverberation on the parameters of the Black-Sea underwater sound channel, (width, drop of the sound velocity, and dimensions of the inhomogeneities of stratification).

We also analyse the behaviour of the intensity of Author: M. Divizinyuk. The book conveys the pride that the people (and governments!) associated with these vessels had for their ships. As the author states, the Blue Riband was never a formal competition. As a consequence, there never was an official history kept about it.

However, this book does an excellent job of filling that void/5(9). Reverberation Time (RT) is the number of seconds it takes for the reverberant sound energy to die down to one millionth (or 60dB) of its original value from the instant that the sound signal ceases.
