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 (medical instrument)

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

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:

Bakes sounds, also known as rosebud or bullet sounds, have a long thin metal rod with a bulbous bud on the end.

Dittel sounds have a flat end and a rounded end.

Henk sounds have a more pronounced curve at the ends, as well as a metal rib on each end.

Pratt sounds are longer urethral dilators (double ended ones are usually almost a foot long) with rounded and slightly bent ends.

Van Buren sounds have a very pronounced tips and applicators

Uterine 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.

Ang (surname)

Ang is a Hokkien and Teochew romanization of the Chinese surnames Wang (汪, Wāng) and Hong (洪, Hóng).

Distribution

In mainland China and Taiwan, names are recorded in Chinese characters and officially romanized using Hanyu Pinyin.

However, Ang was the 12th-most-common surname among Chinese Singaporeans in the year 2000. In Southeast Asia, most of the Ang descendents have settled in Singapore and Penang. Their ancestors came from mainland China, mostly from Fujian, and some of their history could be traced up to four generations. A significant number of Ang descendents could be found in the Philippines. In the United States, it is much less common: the surname ranked 18,359th in 1990 and 11,317th in the year 2000.

ANGPT2

Angiopoietin-2 is a protein that in humans is encoded by the ANGPT2 gene.

Naturally occurring antagonist for both ANGPT1 and TIE2; expressed only at the sites of vascular remodeling; similar to angiopoietin-1

Interactions
