Chatter is a signals intelligence term, referring to the volume (quantity) of intercepted communications. Intelligence officials, not having better metrics, monitor the volume of communication, to or from suspected parties such as terrorists or spies, to determine whether there is cause for alarm. They refer to the electronic communication as ...
Preload can still be approximated by the inexpensive echocardiographic measurement end-diastolic volume or EDV. Preload increases with exercise (slightly), increasing blood volume (as in edema, excessive blood transfusion (overtransfusion), polycythemia) and neuroendocrine activity (sympathetic tone). An arteriovenous fistula can increase ...
Low pressure baroreceptors are primarily involved in the regulation of the blood volume. Low pressure baroreceptors have both circulatory and renal effects, which produce changes in hormone secretion. Stimulation of these receptors causes the atria to release atrial natriuretic peptide. This hormone acts on the kidneys to increase sodium ...
However, there is increasing evidence that CVP, whether as an absolute value or in terms of changes in response to fluid, does not correlate with ventricular volume (i.e. preload) or volume-responsiveness, and so should not be used to guide intravenous fluid therapy. [2] [3] Nevertheless, CVP monitoring is a useful tool to guide hemodynamic ...
Using monitor speakers instead of in-ear monitors typically results in an increase of stage volume, which can lead to more feedback issues and progressive hearing damage for the performers in front of them. [13] The clarity of the mix for the performer on stage is also typically compromised as they hear more extraneous noise from around them.

The MediaMate included magnetic shielding so that they could be placed near a CRT computer monitor without causing the monitor's image to distort. They had dual inputs and two sources (such as a CD player and a computer game) to be played simultaneously, with a dial to adjust the relative level of the two sources.
