What is a good value for dB attenuation?
A good value for dB attenuation depends on the specific application. In general, higher dB attenuation values indicate better noise reduction or signal loss. For example, a dB attenuation value of 20-30 dB is commonly seen in noise-canceling headphones, while 40-60 dB attenuation is typical for industrial ear protection.
How does noise attenuation technology work to reduce unwanted sounds in a given environment?
Noise attenuation technology works by using materials or devices to absorb, block, or cancel out unwanted sounds in a specific environment. This can be achieved through the use of sound-absorbing materials, soundproofing barriers, or active noise-cancelling technology that emits sound waves to counteract and reduce incoming noise.
What is the actually meaning of attenuation according of ultra sound?
Attenuation in ultrasound refers to the weakening of the ultrasound beam as it travels through tissue. This weakening is due to factors like absorption, scattering, and reflection of the sound waves by tissues. Attenuation is important in determining image quality and depth of penetration in ultrasound imaging.
What are the differences between low attenuation and high attenuation in terms of signal strength in a communication system?
Low attenuation refers to a situation where the signal strength remains strong over long distances, resulting in minimal loss of signal quality. High attenuation, on the other hand, indicates a significant decrease in signal strength over distance, leading to potential loss of signal quality.
What is the difference between crosstalk and attenuation?
well both attenuation and crosstalk are used extensively in communications especially in data communications. the difference between the two is how they both affect signal or intelligence run across a media from a point of origin to a destination. attenuation is the degradation of the signal due to various reasons such as noise introduction, lossy media, distance, and the like. crosstalk however is the interference of signal to an adjacent one whereby affecting the signal's essence. usually cause by radiation of electromagnetic induction run through a media usually copper. usually a high frequency transmitted over a wired media causes crosstalks to adjacent ones if proper shielding is neglected, however attenuation may also occur if the signal is projected towards a lossy media over a long distance and with the presence of noise. both are always introduce in a communication environment but have their differences where one degrades while the other affects signal. A UTP network cable consists of four 'pairs' of wires. The two wires in each pair are twisted around eachother to help provide immunity to interference. If we consider a signal being sent down one pair in isolation, then the attenuation of the cable is the degree to which the signal gets reduced in magnitude as it travels down the cable and comes out the other end. As mentioned, this causes degradation of the signal because as you get less and less signal then the noise, interference etc also present on the cable becomes more significant and can corrupt the data. Crosstalk is the extent to which a signal sent down one pair of the cable also appears on another pair. The cross-coupling occurs by electromagnetic induction, and the 'unwanted' signal due to the crosstalk also contributes to the noise on the pair that competes with the wanted signal. The twisting of the pairs aims to reduce the induction, lowering both the crosstalk between the pairs within the cable and interference induced from outside. What determines the attenuation is a little more complex, but basically it's to do with how the construction of the cable matches the frequency being used. The higher the data rate (anf hence frequency of the signal) the 'better' the cable has to be and the tigher the manufacturing tolerances

What is the difference between noise of computer and noise of television?
a noise of a computer is lower than atelivision
Explain the difference between music and noise?
Music can be coined as structured, organized noise.
What is the difference between voice and noise?
the difference between voice and noise is the voice is somebody speaking and it is smooth and mellow and noise means loud and mad if you think say noise in your head when you say noise you just no what it means loud big and it could mean danger as well.
What is the difference between attenuation and insertion loss?
In CATV system, insertion loss define as loss in directional coupler or TAP connector. typically 1 dBuv, while attenuation is generally describe as loss in transmission (splitter).

What is the difference between RG11 and RG213 cable?
RG-11/U is 75ohm and is usually triple/quad shielded and typically has a maximum attenuation of 3.65. RG-213/U is common form amateur radion and is 50 ohms and is single shielded with about a 5.95 attenuation.
