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.

Comes

Comes (/ˈkoʊmiːz/ KOH-meez), plural comites (/ˈkɒmɪtiːz/ KOM-i-teez), is the Latin word for "companion", either individually or as a member of a collective known as comitatus, especially the suite of a magnate, in some cases large and/or formal enough to have a specific name, such as a cohors amicorum. The word comes derives from com- "with" + ire "go."

Ancient Roman religion

Comes was a common epithet or title, added to the name (as Catholicism still does with Jesus and much-venerated saints, such as in Our Lady of Lourdes) for a hero or a divinity, as a way to mark a relationship with another divinity.

On Constantine I's coinage, the emperor is declared comes to Sol Invictus, the "Unconquered Sun" conceived of as a god.

Imperially bestowed court titles and various offices of Comites

Historically more significant, Comes became a secular title given to trusted (ex-)courtiers and others, as a mark of imperial confidence. It developed into a formal rank, deriving from the "Companions" of Alexander the Great, and rather equivalent to the Hellenistic Philos (Basilikos) or the paladin title of a Holy Roman Empire knight and a papal official. Thus the title was retained when one was appointed—often promoted—to a post away from court, often in the field or provincial administration. Next, it seemed logical to link it to specific charges calling for an incumbent of high rank, and even to make it part of the official title.

Canon (music)

In music, a canon is a contrapuntal compositional technique or texture that employs a melody with one or more imitations of the melody played after a given duration (e.g., quarter rest, one measure, etc.). The initial melody is called the leader (or dux), while the imitative melody, which is played in a different voice, is called the follower (or comes). The follower must imitate the leader, either as an exact replication of its rhythms and intervals or some transformation thereof (see "Types of canon", below). Repeating canons in which all voices are musically identical are called rounds—"Row, Row, Row Your Boat" and "Frère Jacques" being widely known examples. An example of a classical strict canon is the Minuet of Haydn's String Quartet in D Minor, Op. 76, No. 2 (White 1976, 66).

Accompanied canon is a canon accompanied by one or more additional independent parts which do not take part in imitating the melody.
