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:

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.

Bat (goddess)

Bat was a cow goddess in Egyptian mythology depicted as a human face with cow ears and horns. By the time of the Middle Kingdom, her identity and attributes were subsumed within the goddess Hathor.

Worship

The worship of Bat dates to earliest times and may have its origins in Late Paleolithic cattle herding. Bat was the chief goddess of Seshesh, otherwise known as Hu or Diospolis Parva, the 7th nome of Upper Egypt.

Name

The epithet Bat may be linked to the word ba with the feminine suffix 't'. A person's ba roughly equates to his or her personality or emanation and is often translated as 'soul'.

Depictions in ancient Egyptian culture

Although it was rare for Bat to be clearly depicted in painting or sculpture, some notable artifacts (like the upper portions of the Narmer Palette) include depictions of the goddess in bovine form. In other instances she was pictured as a celestial bovine creature surrounded by stars or as a human woman. More commonly, Bat was depicted on amulets, with a human face, but with bovine features, such as the ears of a cow and the inward-curving horns of the type of cattle first herded by the Egyptians.

Bata (god)

Bata from Saka is an Egyptian bull-god of the New Kingdom, who represents together with Anubis the 17th Upper Egyptian Nome.

History

Until the middle of the Eighteenth Dynasty Bata was represented as a ram and later as a bull. Bata is probably identical with the death god Bt of the Egyptian Old Kingdom, known from the Saqqara necropolis, for instance from the Mastaba of Ti. Bata is not mentioned in the Pyramid Texts and Coffin Texts.

In literature

Bata is the name of the protagonist in the Tale of Two Brothers, a copy of which survives on the New Kingdom Papyrus D’Orbiney, where he is the brother of Anubis. He is also mentioned in the Ptolemaic Papyrus Jumilhac.
