Sound

In physics, sound is a vibration that propagates as a typically audible mechanical wave of pressure and displacement, through a medium such as air or water. In physiology and psychology, sound is the reception of such waves and their perception by the brain.

Acoustics

Acoustics is the interdisciplinary science that deals with the study of mechanical waves in gases, liquids, and solids including vibration, sound, ultrasound, and infrasound. A scientist who works in the field of acoustics is an acoustician, while someone working in the field of acoustical engineering may be called an acoustical engineer. An audio engineer, on the other hand is concerned with the recording, manipulation, mixing, and reproduction of sound.

Applications of acoustics are found in almost all aspects of modern society, subdisciplines include aeroacoustics, audio signal processing, architectural acoustics, bioacoustics, electro-acoustics, environmental noise, musical acoustics, noise control, psychoacoustics, speech, ultrasound, underwater acoustics, and vibration.

Urethral sounding

Sounding or urethral sounding is the medical use of probes called sounds to increase the inner diameter of the urethra and to locate obstructions in it. Sounds are also used to stretch the urethra in order to receive genital piercing.

Urethral sounding and urethral play are also used to refer to this practice in a sexual context.

Urethral play can involve the introduction of either soft or rigid items into the meatus of the penis (as well as farther in). Objects such as sounds are usually only inserted about halfway into the glans and can usually be easily retrieved. Other toys and items, such as catheters, may be introduced deeper; in some cases even into the bladder. Some items may even be allowed to curl several times or expand within the bladder. This action in the male may be directly or indirectly associated with stimulation of the prostate gland and some types of bladder control.

Risks

If not conducted carefully, sounding carries a risk of irritation, tearing of the urethra, or of urinary tract infection. Infections may become serious if they progress to the bladder or kidneys, and should be referred to a doctor.

Sound (nautical)

In nautical terms, the word sound is used to describe the process of determining the depth of water in a tank or under a ship. Tanks are sounded to determine if they are full (for cargo tanks) or empty (to determine if a ship has been holed) and for other reasons. Soundings may also be taken of the water around a ship if it is in shallow water to aid in navigation.

Methods

Tanks may be sounded manually or with electronic or mechanical automated equipment. Manual sounding is undertaken with a sounding line- a rope with a weight on the end. Per the Code of Federal Regulations, most steel vessels with integral tanks are required to have sounding tubes and reinforcing plates under the tubes which the weight strikes when it reaches the bottom of the tank. Sounding tubes are steel pipes which lead upwards from the ships' tanks to a place on deck.

Electronic and mechanical automated sounding may be undertaken with a variety of equipment including float level sensors, capacitance sensors, sonar, etc.

Insider

An insider is a member of any group of people of limited number and generally restricted access. The term is used in the context of secret, privileged, hidden or otherwise esoteric information or knowledge: an insider is a "member of the gang" hence knows things outsiders don't, including insider jargon.

In our complicated and information-rich world, the concept of insider knowledge is popular and pervasive, as a source of direct and useful guidance. In a given situation, an insider is contrasted with an outside expert: the expert can provide an in-depth theoretical analysis that should lead to a practical opinion, while an insider has firsthand, material knowledge. Insider information may be thought of as more accurate and valuable than expert opinion.

Roles

There are many popular cultural roles ascribed to the insider.

In criminal and social justice, whistle-blowing and leaks are seen as (often heroic) efforts of individual insiders to right wrongs by making secret information public, usually in David and Goliath situations (e.g. by revealing transgressions of governments, large corporations or other powerful organizations). When whistle-blowers are cultivated by outside forces, they are known as informants and informers.

Insider (album)

Insider is the second album of the Manchester alternative rock band Amplifier. It was released in 2006 by the German-based label SPV on 29 September in Germany and Austria then in the rest of Europe on 2 October.

Stargate SG-1 (season 10)

The final season of the series concluded after 20 episodes on March 13, 2007 on British Sky One, which overtook the Sci-Fi Channel in mid-season. The series was developed by Brad Wright and Jonathan Glassner. Brad Wright, Robert C. Cooper, Joseph Mallozzi, and Paul Mullie served as executive producers. Season ten regular cast members include Ben Browder, Amanda Tapping, Christopher Judge, Beau Bridges, Claudia Black, and Michael Shanks.

The season (and the Ori arc of the show) is continued with direct-to-DVD film Stargate: The Ark of Truth.

Reception

Will O'Brien of TV Squad thought "Company of Thieves" was, for the most part, a good one, despite a disappointing performance by Rudolf Martin. Jason Van Horn of IGN, however, was less than impressed, suggesting that the episode just wasn't interesting – that the Lucian Alliance was an enemy no one cares about and that Paul Emerson wasn't enough of a character within the show for his death to have had any meaningful impact.
