sound (redirected from discontinuous sounds)

sound (sound)

1. a pressure wave propagating through an elastic medium; waves with a frequency of 20–20,000 Hz cause the sensation of hearing.

2. the effect produced on the organ of hearing by vibrations of the air or other medium.

3. a noise, normal or abnormal, heard within the body.

4. an instrument to be introduced into a cavity to detect a foreign body or to dilate a stricture.

adventitious sounds  abnormal auscultatory sounds heard over the lung, such as rales, rhonchi, or abnormal resonance.

aortic second sound  the audible vibrations related to the closure of the aortic valve; symbol A2.

auscultatory sounds  those heard on auscultation, such as breath sounds, heart sounds, and adventitious sounds.

breath sounds  respiratory s's; sounds heard on auscultation over the respiratory tract; bronchial and ventricular ones are heard normally at certain places, whereas a cavernous one indicates a lung cavity.

continuous sounds  adventitious sounds lasting longer than 0.2 sec, such as wheezes and rhonchi.

discontinuous sounds  adventitious sounds lasting less than 0.2 sec and coming in a series; the most common are rales.

ejection sounds  high-pitched clicking sounds heard just after the first heart sound, at maximal opening of the semilunar valves; seen in patients with valvular abnormalities or dilatations of aortic or pulmonary arteries.

friction sound  see under rub.

heart sounds  sounds heard over the cardiac region, produced by the functioning of the heart. The first, at the beginning of ventricular systole, is dull, firm, and prolonged, and heard as a “lubb” sound; the second, produced mainly by closure of the semilunar valves, is shorter and sharper than the first and is heard as a “dupp” sound; the third is usually audible only in youth; and the fourth is normally inaudible.

hippocratic sounds  succussion s's.

Korotkoff sounds  sounds heard during auscultatory determination of blood pressure.

percussion sound  any sound obtained by percussion.

pulmonic second sound  the audible vibrations related to the closure of the pulmonary valve; symbol P2.

respiratory sounds  breath s's.

succussion sounds  splashing sounds heard on succussion over a distended stomach or in hydropneumothorax.

to-and-fro sound  see under murmur.

urethral sound  a long, slender instrument for exploring and dilating the urethra.

valvular ejection sound  an ejection sound resulting from abnormality of one or both semilunar valves.

vascular ejection sound  an ejection sound resulting from abnormality of the pulmonary artery or aorta without abnormality of either semilunar valve.

voice sounds  auscultatory sounds heard over the lungs or airways when the patient speaks; increased resonance indicates consolidation or effusion.

white sound  that produced by a mixture of all frequencies of mechanical vibration perceptible as sound.

2. Transmitted vibrations of any frequency.

3. A distinctive noise.

v.

To auscultate.

---

sound ² (sound)

adj.

1. Free from defect, decay, or damage; in good condition.

2. Free from disease or injury.

---

sound ³ (sound)

n.

An instrument used to examine or explore body cavities, as for foreign bodies or other abnormalities, or to dilate strictures in them.

v.

To probe a body cavity with a sound.

sound

Etymology: L, sub, under, unde, wave

an emission detected by an instrument used to locate the opening of a cavity or canal, to test the patency of a canal, to ascertain the depth of a cavity, or to reveal the contents of a canal or cavity. A sound is used to determine the depth of the uterus, to detect stones in the bladder, and, less commonly, to assist in correctly inserting a urinary catheter in the urethra through the urinary meatus.

sound

1. percept resulting from stimulation of the ear by mechanical radiant energy, the frequency depending on the species.

2. a slender instrument to be introduced into body passages or cavities, especially for the dilatation of strictures or detection of foreign bodies.

3. a noise, normal or abnormal, emanating from within the body.

4. strong, in good condition and without significant defects, e.g. said of wool which has sufficient tensile strength to resist the rigors of processing; said also of teeth as sound mouth.

ejection s's

high-pitched clicking sounds heard very shortly after the first heart sound, attributed to sudden distention of a dilated pulmonary artery or aorta or to forceful opening of the pulmonic or aortic cusps.

friction sound

one produced by rubbing of two surfaces.

heart s's

the sounds produced by the functioning of the heart. See heart sounds.

Korotkoff's s's

those heard during auscultatory blood pressure determination.

percussion sound

any sound obtained by percussion.

respiratory sound

any sound heard on ausculation over the respiratory tract.

succussion s's

splashing sounds heard on succussion over a distended stomach or in hydropneumothorax.

to-and-fro sound

a peculiar friction sound or murmur heard in pericarditis and pleurisy.

urethral sound

a long, slender instrument for exploring and dilating the urethra.

sound waves

sound, the stimulus for hearing, consists of patterns of pressure waves generated in and passed through the air.

white sound

that produced by a mixture of all frequencies of mechanical vibration perceptible as sound.

Patient discussion about discontinuous sounds.

Q. Atkins diet? Is it good as it sounds? I'm 17..about 5'2 145 lbs.. I need to lose as much weight as possible in 3 weeks ..Anyone know what kind of results i can expect on atkins?

A. the atkins is a fad diet. because the atkins is high in protein it suppresses your appetite and you won't feel hungry so you'll eat less while still being full. as ideal as that sounds it doesn't work for long term weight loss. it is proven that once you begin to eat normally again the weight will come back on and possibly even more. carb free diets are the worst because you crave carbs like crazy and once you finally let yourself eat some you'll most likely binge. i've seen it happen to so many people. then once they start, they continue to
binge and before you know it the weight is back. it's not a healthy diet, trust me

Q. In the meanwhile can someone give any hints if this sounds like diabetes or is a natural occurrence? My husband and I are diabetic. My daughter is pregnant and has been fine so far. My daughter says that fluids are good for her and she drinks a lot of water. She also keeps snacking on a bag of toffees. Every day I see the same ritual. She says she is always hungry. She has a craving to eat anything that is sweet. I suspect that there is something wrong her. In the meanwhile can someone give any hints if this sounds like diabetes or is a natural occurrence?

A. One thing I learned from my doctor is that the body will attempt to eliminate high blood sugar by making you urinate more frequently. This is what makes you thirsty when your blood glucose is high, making you want to drink more and more. It causes the dry mouth in the morning when you wake up. This is what I was experiencing with my diabetic condition before I was diagnosed. I am an insulin resistsnt (type II) diabetic.

Thirst is just one symptom.

Getting an A1c test will determine if there is diabetes. You have to see a doctor for that and the results are usually irrefutable.

Eating sugar candy will raise the blood glucose level. This would be dangerous for a diabetic.

Tell the tohe doctor and get her tested or evaluated and then you will know the real medical condition. All any of us can do on a forum like this is share experiences and info we learn. Nothing anyone suggests can substitute for what a doctor can easily determine for something like this with a blood test.

Q. what causes the sound of cracking noises in the head all the time it was said i had acute sinusitis but honestly i think it is more . I don't know why i have cracking noises in my head . I am very concerned about this also my neck is always stiff feeling and aching all the time. . My eyes are very tired and i see blue spots and they hurt behind the eye very badly . I have headaches very often

A. wow...that really sounds serious...i have chronic sinusitis and i can tell you i had horrible headaches but nothing like you describe now. i would strongly consider going to a hospital and checking it out...
tell us what was the result!
