| acceptable daily intake | <pharmacology> This is an estimate of the amount of a substance in food that can be ingested daily over a lifetime by humans without appreciable health risk. The concept of the acceptable daily intake has been developed principally by who and FAO and is relevant to chemicals such as additives to foods, residues of pesticides and veterinary drugs in foods. Acceptable daily intakes are derived from laboratory toxicity data, and from human experiences of such chemicals when this is available, and incorporate a safety factor. The acceptable daily intake is thus an estimate of the amount of a substance in food that can be ingested over a lifetime by humans without significant risk to health (for contaminants in food and drinking water, tolerable intakes - daily or weekly - are used). See: tolerable daily intake. (15 Jan 1998) |

| acceptable risk | <statistics> This relates to the potential for suffering disease or injury that will be tolerated by an individual, group, or society in exchange for the benefits of using a substance or process that will cause such disease or injury. Acceptability of risk depends on scientific data, social, economic, and political factors, and on the perceived benefits arising from a chemical or process that creates the risk in question.

| hearing loss, noise-induced | Hearing loss from exposure to noise. The loss is often in the frequency range 4000-6000 hertz. (12 Dec 1998) |
| signal-to-noise ratio | <microscopy> Also sometimes used as an abbreviation for serial number, can be somewhat confusing in the case of electronic equipment. (05 Aug 1998) |
| structured noise | In radiology, the signals from anatomic structures which interfere with the detection of significant pathology. (05 Mar 2000) |
| noise | 1. Sound of any kind. "The heavens turn about in a most rapid motion without noise to us perceived." (Bacon) Noise is either a sound of too short a duration to be determined, like the report of a cannon; or else it is a confused mixture of many discordant sounds, like the rolling of thunder or the noise of the waves. Nevertheless, the difference between sound and noise is by no means precise. 2. Especially, loud, confused, or senseless sound; clamor; din. 3. Loud or continuous talk; general talk or discussion; rumor; report. "The noise goes." "What noise have we had about transplantation of diseases and transfusion of blood!" (T. Baker) "Soerates lived in Athens during the great plague which has made so much noise in all ages." (Spectator) 4. Music, in general; a concert; also, a company of musicians; a band. "The king has his noise of gypsies." (B. Jonson) Synonym: Cry, outcry, clamor, din, clatter, uproar. Origin: F. Noise noisy strife, quarrel, brawl, fr. L. Nausea seasickness, sickness, disgust. See Nausea. Source: Websters Dictionary (01 Mar 1998) |
| noise-induced deafness | A type of sensorineural deafness caused by prolonged exposure to loud sounds, e.g., jet engines. (05 Mar 2000) |
| noise, occupational | Noise present in occupational, industrial, and factory situations. (12 Dec 1998) |
| noise, transportation | Noise associated with transportation, particularly aircraft and automobiles. (12 Dec 1998) |
| optical noise | <microscopy> Image defects that become especially conspicuous when the image is enhanced. In video microscopy, includes hot spots, mottle, uneven illumination, etc. (05 Aug 1998) |
| ACE level | <investigation> This is a blood test which measures the concentration of angiotensin-converting enzyme (ACE) in the bloodstream. Elevations in angiotensin-converting enzyme are seen sarcoidosis, histoplasmosis, alcoholic cirrhosis, asbestosis, berylliosis, diabetes, Hodgkin's disease, hyperthyroidism, amyloidosis, primary biliary cirrhosis, idiopathic pulmonary fibrosis, pulmonary embolism, scleroderma, silicosis, tuberculosis, Gaucher's disease and leprosy. The normal values are 18 to 67 U/ml over 20 years of age (people under 20 have higher levels). (15 Jan 1998) |
| acoustic reference level | The biological reference level for sound measurements. When the term decibel is used to indicate the noise level, a reference quantity is implied; this reference value is usually expressed as a sound pressure of 20 micronewtons per square meter. The reference level is referred to as 0 decibels, the baseline of the scale of noise level's; this baseline is considered the weakest sound that can be heard by a person with very good hearing in an extremely quiet location. Other equivalent reference level's still being used include 0.0002 microbar and 0.0002 dyne per square centimeter. (05 Mar 2000) |
| background level | The average amount of a substance present in the environment. Originally referring to naturally occurring phenomena. Used in toxic substance monitoring. (05 Dec 1998) |
| blood porphyrin level | A test which is used to measure red blood cell porphyrin levels. Porphyrins are pigments found in both animal and plant life. This test is useful in evaluating any number of porphyrin disorders (involving the various porphyrins) of red blood cells. Increased levels of coproporphyrins can indicate congenital erythropoietic porphyria or sideroblastic anaemia. Increased protoporphyrins may be seen in infection, thalassaemia, sideroblastic anaemia, iron deficient anaemia, increased erythropoiesis and lead poisoning. Increased uroporphyrins may indicate congenital erythropoietic porphyria or erythropoietic protoporphyria. (27 Sep 1997) |
| carbon dioxide blood level | A measure of the bicarbonate level in the blood based on a venipuncture specimen. The serum carbon dioxide is one of the normally reported values in the electrolytes profile. Lower levels of carbon dioxide indicate an acidosis. The normal level is 20 to 29 mEq/L. Lower than normal levels can indicate diabetic ketoacidosis, lactic acidosis, alcoholic ketoacidosis, kidney disease, renal failure, diarrhoea, Addison's disease, ethylene glycol poisoning or methanol poisoning. Greater than normal levels can be seen with excessive vomiting, hyperaldosteronism and Cushing's syndrome. (27 Sep 1997) |
