Example Input: When you speak, sound waves created by your voice carry energy toward the microphone. Inside the microphone, the diaphragm moves back and forth when the sound waves hit it. The coil, attached to the diaphragm also moves back and forth. The permanent magnet produces a magnetic field that cuts through the coil. How Electret Microphones Work. With the diaphragm and the back plate ready to receive sound waves, they work by letting the incoming sound waves from a source of sound from any direction to change the capacitance between the two conducting plates. March 31, 2015. A carbon mic is a simple device to turn sound waves into an electronic signal. Carbon microphones were used in telephones, radio broadcast systems and many other devices through the 80s. microphone's directional sensitivity, which is how a microphone picks up sound from different directions. These are the three most common polar patterns: CARDIOID These patterns pick up the most sound from in front of the microphone and some from the sides They are less susceptible to feedback in loud environments. SUPERCARDIOID Or you could amplify (boost the size of) the current and then feed it into a loudspeaker, turning the electricity back into much louder sound.

In a microphone, there are almost identical parts but they work in exactly the reverse way. How microphones work How does a microphone turn sound energy into electrical energy? A: A wireless microphone works by using a wireless transmitter, which is incorporated into the microphone or attached to a body pack transmitter. The battery-operated wireless transmitter includes an antenna for broadcasting sounds. Query: how does a microphone work
Example Output: A wireless microphone works by using a wireless transmitter, which is incorporated into the microphone or attached to a body pack transmitter. The battery-operated wireless transmitter includes an antenna for broadcasting sounds.

Example Input: The most popular kind of drug test is the urine test, which can detect marijuana for days or weeks after use. As shown in the following graph, detection times for chronic users typically range from one to three weeks but can extend much longer. In this study by Ellis [04], chronic users were tested at 20 ng/ml and 100 ng/ml, but not at the normal standard of 50 ng/ml. Hair tests are more likely to detect regular than occasional marijuana use. One study found that 85% of daily users tested positive for marijuana, versus 52% of occasional smokers (1-5 times per week). Ingested cannabis was less likely to be detected than smoked marijuana . Advil) will not test positive for marijuana on modern drug screens, but numerous OTC cold remedies may trigger false positive results for amphetamines, primarily on the EMIT test.

Lasix (ferosemide) is one of many stronger diuretics available by prescription. While non-prescription use of Lasix can potentially be hazardous to health if taken over long lengths of time, its use has been popular for more than two decades by those subject to random workplace drug tests on short notice. M metabolite Blood tests, unlike urinalysis, detect the presence illicit drugs, not inactive drug metabolites.

Ingested cannabis was less likely to be detected than smoked marijuana [01]. Query: how long can marijuana residue be detected
Example Output:
The residual levels in cannabis consumers may be detected in chronic smokers for up to 12-24+ hours if more sensitive technology is used.
