What is the difference between directivity index and directivity factor in relation to sound and vibrations?
you dont know..neither I do
How do you obtain the directivity curve of the microphone?
Go in always the same distance with a loudspeaker and a pure tone arround the microphone and measure the microphone's output. You get a damping curve which is the directivity curve.
What is the advantage of parabolic reflective antennae?
parabolic reflector having highest directivity.
What are the features of microwave communication?
high directivity high beam width low power transmitter is needed
What is the Application of measurement of directivity and sensitivity using microphone?
The Application of: Directivity- Microphones are made differently. Some microphones pick up sounds only from directly in front of them. Other microphones are pick up sounds well from all directions. The directivity shows all the various sides and angles from which a microphone can pick up sounds. Sensitivity- The sensitivity of a microphone is the gain at which the microphone can pick up sounds. Microphones with high sensitivity can pick up sounds with high gain.
What are directivity and radar cross srction?
Radar cross section is a measure of the electromagnetic energy intercepted and reradiated at the same frequency
What is the advantage of microwave frequency over low frequency?
larger bandwidth beter directivity lower power requirement less fading effect
How is sound projected?
The directivity (narrowness) of all wave producing sources depends on the size of the source, compared to the wavelengths it generates. Audible sound has wavelengths ranging from a few inches to several feet, and because these wavelengths are comparable to the size of most loudspeakers, sound generally propagates omnidirectionally. Only by creating a sound source much larger than the wavelengths it produces can a narrow beam be created. In the past, loudspeaker manufacturers have created large speaker panels or used reflective domes to provide some directivity but, due to the sound's large wavelengths, the directivity of these devices is still extremely weak.
What is the formula to calculate directivity?
there is no specific formula to calculate direct cost but direct cost are all those costs which are directly related to production of goods and separately identifiable.
What has the author Eleazer Bromberg written?
Eleazer Bromberg has written: 'Mathematical theory of the influence of a dome on the directivity pattern of sound beams, Part 4' -- subject(s): Accessible book
