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 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.
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.
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.
In medicine, sounds are instruments for probing and dilating passages within the body, the best-known examples of which are urethral sounds and uterine sounds. Some people enjoy using them for urethral play.
Urethral sounds are designed to be inserted into the male or female urethra, for the purpose of stretching or unblocking a stricture. There are a number of different types of urethral sounds:
These sounds or dilators are intended for probing a woman's uterus through the cervix, to measure the length and direction of the cervical canal and uterus, to determine the level of dilation, or to induce further dilation.

Fargo may also refer to:
Fargo was a brand of truck originally produced in 1913 by the Fargo Motor Car Company. Dropped in 1922, the name was reintroduced for a line of trucks manufactured by the Chrysler Corporation after purchasing Fargo Motors in 1928. Later, Chrysler absorbed Dodge and started producing its truck line. Over time, Fargo trucks became rebadged Dodges, similar to the parallel sale by General Motors of its GMC and Chevrolet truck lines, with Fargo being the GMC equalivent.
The first Fargo trucks were built in Chicago by the Fargo Motor Car Company from 1913 until 1922. In 1928 Chrysler bought the business and created their own line of Fargo trucks. Shortly after its creation, Chrysler also bought the Dodge Brothers Company, adding Dodge and Graham Brothers badged trucks to its product line.
From then on, Fargo trucks were almost identical to Dodge models, save for trim and name, and were sold by Chrysler-Plymouth dealers.
U.S. sales were discontinued in the 1930s, but the name Fargo was used until 1972 for Canada, and lived longer for other countries around the world under the Chrysler Corporation's badge engineering marketing approach. Most of the Fargo trucks and bus chassis sold in Argentina,Finland, Australia, India, and other countries in Europe and Asia were made in Chrysler's Kew (UK) plant. Most were sold also under the Dodge, Commer or DeSoto names.
Fargo (previously, the Great Northern Depot and the Burlington Northern Depot) is a train station in Fargo, North Dakota, United States. It is served by Amtrak's Empire Builder and North Coast Hiawatha trains. It is the only railway station in use in the Fargo-Moorhead area and is the third busiest in North Dakota. The platform, tracks, and station are currently all owned by BNSF Railway. The station is currently located in the former BNSF freight house. The former main station building is now home to Great Northern Bicycle Co.
Fargo Station was originally built by the Great Northern Railway in 1920.
At the time of the station's construction, Fargo was served by both the Great Northern Railroad and the Northern Pacific. The station was served by Great Northern trains, while Northern Pacific operated its own station along Fargo's Main Avenue.
In 1970, the two railway companies merged to form the Burlington Northern. Freight trains used the Northern Pacific tracks, while passenger trains used the Great Northern tracks. All passenger service in Fargo began using the Great Northern depot. From 1971, passenger service was operated by Amtrak.
