A parabolic microphone uses a parabolic parabolic microphone kit plans reflector to collect and focus sound waves onto a microphone receiver, how to make a parabolic microphone in much the same way that a parabolic antenna (e.g. satellite dish) does with radio waves. Typical parabolic microphone plans uses of this microphone, which has unusually focused parabolic microphone professional version front sensitivity and can pick up sounds from many meters away, include nature recording, eavesdropping, law enforcement, and even espionage.
Parabolic parabolic microphone wiring diagram microphones do it yourself parabolic microphone are generally not used for standard recording applications, because they homemade parabolic microphone plans tend to have poor low-frequency response as a side effect of their design. This is a direct result of the physical laws that govern sound waves. Parabolas parabolic microphone toy building a parabolic microphone only focus diy parabolic make your own parabolic microphone microphone waves with a wavelength much smaller than the diameter of the parabola. Since sound waves travel at 300 m/s through parabolic microphone military the ultra cardioid parabolic microphone air parabolic microphone (speed of sound), to get hi-fidelity sound (down to 20 Hz, the lower limit of human hearing) would require a parabola with a diameter greater than 300 m/s / 20 Hz = 15 meters in diameter. Most parabolic microphones sacrifice fidelity to get a more manageable size.

Electronics Topics
The field of electronics is the study and use of systems that operate by controlling the flow of electrons or other electrically charged particles in devices such as thermionic valves and semiconductors. The design and construction of electronic circuits to solve practical problems is part of the fields of electronic engineering, and the hardware design side of computer engineering. The study of new semiconductor devices and their technology is sometimes considered as a branch of physics.
