This chapter documents the collateral impacts of immigration detention on centre visitors in Australia. It notes that many visitors derive benefits from their visitation relationships, but also highlights the traumatizing dimensions of the visitation experience. Visiting immigration detention, this chapter shows, involves witnessing trauma.

A method for extending reverberation time of Dattorro's reverberator
2015 12th International Conference on Fuzzy Systems and Knowledge Discovery (FSKD), 2015Based on the introduction of the digital reverberation algorithm, we use the integrated impulse response method, and the method of compressing and extending the reverberation model impulse response to solve two existing problems of the Dattorro's plate reverberator in the practical application.

Electromagnetic Reverberation Chambers
2011Dedicated to a complete presentation on all aspects of reverberation chambers, this book provides the physical principles behind these test systems in a very progressive manner. The detailed panorama of parameters governing the operation of electromagnetic reverberation chambers details various applications such as radiated immunity, emissivity and ...

"Colorless" artificial reverberation [PDF]
IRE Transactions on Audio, 1960 An artificial reverberator is described which has a flat amplitude-frequency response and therefore does not alter the spectral balance or “color” of the reverberated sound. Neither does the reverberator add any extraneous hollow, reedy, or metallic qualities or flutter echoes of its own. The number of echoes per second increases with time according to

Masking of Surface Reverberation by Volume Reverberation
The Journal of the Acoustical Society of America, 1966Measurements of the backscattering of 4-kcps sound from the surface of the sea at a grazing angle of 5° and a wind speed ranging from less than 5 ft (knots) to greater than 35 kt were made off Bermuda. It was assumed that surface backscattering is wind-speed-dependent; volume backscattering, on the other hand, was assumed not to be wind-speed-dependent

Earthquakes and their attendant phenomena rank among the most terrifying natural disasters faced by mankind. Out of a clear blue sky—or worse, a jet-black one—comes shaking strong enough to hurl furniture across the room, human bodies out of bed, and entire houses off their foundations.

Perception of reverberation length in rooms with reverberation enhancement systems
The Journal of the Acoustical Society of AmericaThis study examined the perception of reverberation length in rooms equipped with a reverberation enhancement system (RES). In the past, many acousticians have studied the correlation between subjective reverberation ratings and objective criteria in concert halls; the effect of RES on these ratings has not been thoroughly investigated.

International Symposium on Electromagnetic Compatibility - EMC EUROPE, 2012
One of the main statistical models for fields in reverberation chambers is the so-called 'plane wave integral representation' model of David Hill. However, despite being widely known and used, this model (as stated by D. Hill himself) lacks a rigorous demonstration, especially when extending it to e.g.

The apparatus used to measure ocean reverberation at 24 kc consists essentially of a sound projector which sends a signal of adjustable duration into the water; a hydrophone which translates the backward scattered sound into electrical voltage; an amplifier which increases this voltage; a cathode-ray oscillograph which converts voltage fluctuations ...

The problems associated with acoustic reverberation in the ocean continue to be of prime importance in the use of active sonar. Even though a great amount of effort has been devoted to these problems, they are still not well understood and experimental evidence remains the prime source for an evaluation of the state-of-knowledge, in this field.
