![]() ![]() The fidelity of a column can be no better than that of the individual speakers. The advantage of a column is its simplicity and being visually unobtrusive. Their intended application is for announcements and background music. Often seen in churches, shopping centres, travel terminals, gymnasiums etc. The majority of traditional column systems consist of a vertical row of small speakers. A natural horizontal line source of sound energy is a motor way or a beach. In reality, large line array systems approach this on a limited scale. Sound energy only decreases by 1/2 per double the distance (-3dB/2D). In theory an infinite vertical line source of sound energy can only disperse horizontally. Sound energy dispersing from a point source decreases by 1/4 per double the distance. The explanation below is basic and will be expanded in greater detail when the other chapters in this education site are completed. To understand how sound disperses from a system requires us to think of Frequency as its wavelength. It is often generalised as 344 meters per second or 1ft / milli-second. ![]() Velocity of sound is dependant on temperature, atmospheric pressure and humidity. This reduces intelligibility and limits the overall high frequency energy. Wavelength distances between adjacent boxes and speaker stacks generate intense lobe and comb filter distortion, throughout the music spectrum. Inter-modulation compounds as the power increases (inter-cluttering within the music). Speaker systems set up in clusters for high power cause compromises that restrict fidelity and linear dynamic power handling (sound quality changing in reference to power). (b) 2 15in speakers, four 8in speakers and hi-frequency horn. Each cabinet can be compacted with variations of. This enables practical economic management. The numbers of cabinets is varied to suit the application. Large Clusters For large auditoriums, speaker cabinets are stacked in convex clusters, or vertical lines above the audience. Grouping many speakers together to achieve power is always a compromise that reduces fidelity, regardless of the arrangement the speaker are grouped in, or marketing hype. Theoretically, sound from a single point gives better fidelity. A group of 4in speakers do not sound like a 15in speaker.ī. Also a section of violins do not sound like a cello. Increasing the size of a speaker or musical instrument does not necessarily make it louder, but shifts its efficiency lower in the musical range. Natural frequency of the air-filled tube.A. To see the effect of helium on voice quality, calculate the ratio of the nth natural frequency of the helium-filled tube to the $nth$ The quality of the voice depends on the harmonic frequencies generated by the tube larger frequencies lead to higher-pitched voices. To see why this occurs, assume for simplicity that the voice is generated by the vocal cords vibrating above a gas-filled cylindrical tube that is open only at one end. Helium, however, has the effect of giving the voice a high-pitched quality, like that of Donald Duck’s voice. This danger is for divers to breathe a mixture containing only helium and oxygen. Divers working in underwater chambers at great depths must deal with the danger of nitrogen narcosis (the “bends”), in which nitrogen dissolves into the blood at toxic levels. ![]()

NOTE: The Real Numbers did not have a name before Imaginary Numbers were thought of. Meanwhile, try this to get your feet wet: "What's that last bit, complex number and bi" you ask?! The term "imaginary number" now means simply a complex number with a real part equal to 0, that is, a number of the form bi. ![]() The name "imaginary number" was coined in the 17th century as a derogatory term, as such numbers were regarded by some as fictitious or useless. They have some properties that are different from than the numbers you have been working with up to now - and that is it. Well, it is the same with imaginary numbers. It seemed weird at the time, but now you are comfortable with them. Remember when you first started learning fractions, you encountered some different rules for adding, like the common denominator thing, as well as some other differences than the whole numbers you were used to. They are just extensions of the real numbers, just like rational numbers (fractions) are an extension of the integers. Don't let the term "imaginary" get in your way - there is nothing imaginary about them. ![]() ![]() ![]() Then, when you add an element to the timeline you can select a theme from the properties panel to apply the preset fonts and colours to it. This lets you define the colours and fonts to be used for elements such as text and speech-bubbles. User-defined theming is another new feature. And if you need even more pre-designed intros, outros, backgrounds and music clips you can buy access to 600,000 additional royalty-free assets for $199 a year. Some additional assets are provided with this release. The Library now has its own dedicated panel (show at the left) and it it includes various assets such as the animated background that is being previewed here. I got around this problem by selecting portions of the old Library, exporting those to a Library zip file and then importing them. It also failed when I explicitly exported the 9.1 Library and then attempted to import it. I found that the Library importer failed with my Camtasia 9.1 Library. For example, you can now have multiple named libraries, you can manage assets by moving selected elements from one named library to another, you can enter text to search for an asset and you can automatically import libraries from Camtasia 9.1. In Camtasia 2018 it’s been given its own panel with a few extra capabilities. In Camtasia 9, the Library shared a tabbed panel with the Media clip panel. The Library is a panel where you can store reusable assets – video and audio clips, backgrounds, animated objects, intros and outros and so forth. One of the big changes, according to Techsmith, is the improved Library. You need to look more closely to spot the differences… At first sight, nothing much seems to have changed.

AmnioSense detected 98 per cent of leaks caused by urine and harmless vaginal discharges and 67 per cent of cases where there was a leak of amniotic fluid. The results could be read for up to 12 hours, which is important in a real-world setting as a woman could carry out the test at home, and still have time to get to her midwife or healthcare provider and show them the result while it was still reliable.Ī further study involving 339 women attending hospital with unexplained vaginal wetness found that AmnioSense correctly detected 154 of the 161 cases where a leak of amniotic fluid was confirmed.Ī UK study looked at 157 women attending the antenatal unit at St Thomas’ Hospital in London with a suspected leak of amniotic fluid. Samples of amniotic fluid taken from 50 women, between 16 and 23 weeks gestation, who were undergoing checks for foetal abnormalities showed that in all cases the AmnioSense test gave a positive response to the presence of amniotic fluid. Several studies have confirmed the accuracy, sensitivity and ease of use of Amniosense. AmnioSense provides reassurance and an early warning for pregnant women. Unlike a speculum examination, AmnioSense allows for constant monitoring and ensures small, difficult to diagnose ruptures, such as hind leaks, are detected. Crucially, AmnioSense can detect as little as 100 microliters of amniotic fluid - the equivalent of two drops. The strip changes colour from yellow to blue or green when it comes into contact with any fluid which has a pH of more than 6.5, as is the case with amniotic fluid. It is a thin pantyliner filled with a central polymer-embedded strip which can be worn for up to 12 hours to ensure continuous monitoring. New test offers prompt and accurate diagnosis of amniotic leaksĪmnioSense, is a new evidence-based diagnostic test which has been proven to be as accurate as hospital-based examinations (Ferning test, sterile speculum examination and pH test). However current testing methods do not always detect small ruptures and hind leaks, which is of concern for all maternity and midwifery professionals, as any leak of amniotic fluid increases the risk of a serious neonatal infection (1 per cent compared to 0.5 per cent for women with intact membranes) and early onset of labour, in that 60 per cent of affected women will go into labour within 24 hours. In around 50 per cent of cases, the wetness is urine and the patient may be reassured and return home. It is not standard NHS practice to use acidity or Ferning tests to confirm any pooling is amniotic fluid. Unless there is an obvious rupture of the membranes, a speculum examination will be performed to determine if there is any pooling of amniotic fluid. This requires medical attention as there is a risk of both infection and the early onset of labour. ![]() However, dampness may indicate a premature rupture of the membranes (PROM). In most cases it is harmless, resulting from urinary incontinence or changes to the vaginal mucus. ![]() Around 20 per cent of pregnant women report to hospital or birth units reporting the sensation of wetness.
