What is the definition of diaphragm?
A diaphragm is a thin sheet which separates two volumes or spaces (from Greek for barricade). They are manufactured for a variety of uses; in microphones and earpieces, pumps, and barriers to the passage of sperm for contraception. Many exist in living things, the eardrum being a small but important one. All the above mentioned things would be called a diaphragm. The diaphragm is one particular kind; it is a muscle that is located under the lungs that contracts to let air into the lungs. When the diaphragm "moves down" it causes you to inhale and when your diaphragm relaxes to form a dome shape muscle you exhale. If we didn't have a diaphragm then we wouldn't be able to give birth. The diaphragm also makes us have hiccups! When the regular rhythmic contraction gets disturbed we appear to end up with hiccups.
Are allele frequencies more likely to remain stable in large populations than in small populations?
Yes, allele frequencies are more likely to remain stable in large populations due to the effects of genetic drift being more pronounced in small populations. In small populations, random events can lead to significant changes in allele frequencies, whereas in large populations, genetic drift has less impact and allele frequencies are more likely to remain stable over time.
What body parts start with letter D?
Deltoid - a shoulder muscle. Diaphragm - a muscle that aids in breathing. Dorsal - relating to the back or upper side of an animal. Dorsal fin - the fin located on the back of certain aquatic animals.
What are the organs to the systems belong to digestive?
oral cavity, esophogus, liver, diaphragm, stomach, pancreas, large intestine, rectum, small intestine, gall bladder,
What is The alteration of allelic frequencies by chance processes is known as?
Genetic drift. It refers to the random fluctuation of allele frequencies in a population due to chance events, particularly in small populations. Genetic drift can lead to the loss or fixation of alleles over time.
How do i use a microphone?
First it is very important to chose the right microphone. There are condenser microphones, ribbon microphones, dynamic microphones, and there are electret microphones. There are some different characteristics: omni directional, wide cardioid, cardioid, super cardioid, hyper cardoid and figure-of-eight. There are microphones with small diaphragm diameters and with large diaphragm diameters. There are expensive high quality studio microphones and less ideal very cheap Chinese mics. When you have found the right microphone, then you can start to ask where to put this microphone to which musical instrument or voice.

What is diaphragm gauges?
The diaphragm gauge gives sensitive andreliable indications of small pressure differences.
What is the difference between the velocity operated and pressure operated microphones?
Know your microphones - what is the difference between pressure, pressure gradient, and velocity microphones?David Mellor | November 30, -0001Microphones work on the principle of pressure, pressure gradient, or velocity. If you don't know the difference, then you can't yet call yourself a sound engineer.This is something from the text books. Actually you don't have to know this to be a sound engineer - the proof of that is the 90% of sound engineers that don't know it! Yet a little theory never hurt anyone. And if you know how things work in theory, then you can apply them better in practice.There are two basic types of microphone - omnidirectional and figure-of-eight, which can be made in either dynamic or capacitor forms. Cardioid and hypercardioid microphones are hybrids, combining features of both the omni and figure-of-eight.The omnidirectional microphone works on the pressureprinciple. The diaphragm, which picks up sound vibrations in the air, is completely open at one side, but completely closed at the other.The sound vibration is either pushing the diaphragm against the fixed pressure of the air on the other side, or it is reducing the pressure on the front of the diaphragm allowing the pressure behind to push it out.One of the features of pressure in a gas is that it pushes equally in all directions. "Equally in all directions"? That makes the mic omnidirectional then.[For the sake of completeness, it should be mentioned that there is a tiny hole in the capsule to the rear of the diaphragm. This is so the microphone can compensate for long-term variations in air pressure. The hole is too small to affect its sound characteristics.]The figure-of-eight microphone on the other hand has both sides of the diaphragm fully open to the air. So it doesn't compare the incoming sound pressure with a fixed pressure on the other side of the diaphragm like the omnidirectional microphone. Instead it compares the pressure of the sound wave on one side with the pressure of that same sound wave after it has traveled through to the other side.Yes, it is a tiny difference in pressure, but strong enough to move the diaphragm.The difference in pressure between the front and the back of the diaphragm depends on the angle of incidence of the sound wave. In the extreme, if the sound arrives from the side of the diaphragm, then the pressure will be the same at the front and the rear, therefore the diaphragm will not move and there will be no output.Lastly, the velocity microphone... it doesn't exist! However you will see the term used frequently, particularly in relation to ribbon microphones.A velocity microphone, if it existed, would respond to the actual velocity of the air molecules striking the diaphragm.For this to happen though, the diaphragm would have to be so light that it could respond almost instantaneously, and so thin that there was no pressure difference between the two sides of the diaphragm. In practice, the diaphragm is too heavy to acquire the velocity of the air molecules and it has significant thickness.But a microphone that doesn't make it as a velocity mic, because its diaphragm is too heavy and thick, is still sensitive to pressure gradient. So in practice, these microphones are pressure gradient mics.So now you know it - the difference between pressure, pressure gradient and velocity microphones.
What are the better qualities in a Edirol MP3 player?
The Edirol MP3 player is very small, and has built-in stereo microphones and automatic gain control for audio recording. Plus, you can expand its capacity by adding an SD memory card.
What is the Small Disk under the stage that regulates the amount of light that reaches the specimen?
The small disk under the stage is called the diaphragm. It functions to adjust the amount of light that passes through the specimen on the microscope slide. By adjusting the diaphragm, you can control the intensity and focus of the light on the specimen.
What are the kidneys between?
The kidneys are above the large and small intestine and there is the diaphragm above it
What speaker handles high frequencies?
The small speaker called the 'tweeter'.
Does lady gaga have wireless microphone on her to make her sing better?
If you mean "right this instant", she's not here just now, so I don't know. Wireless microphones do not make you "sing better." Microphones convert sound into electrical signals which can then be processed and/or amplified, but they aren't magic sing-better devices, not even the wireless ones. It is unusual, to say the least, for a pop artist performing in even a small venue to NOT use a microphone of some kind, and wireless ones are generally more convenient than wired ones.
