Noise refers to unwanted random signals that can distort or interfere with the transmission of a desired signal. Attenuation, on the other hand, is a reduction in the strength of a signal as it travels through a medium, such as a cable or fiber optic line. Attenuation can result from factors like distance, obstacles, or the characteristics of the medium itself.

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.
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 is the opposite of attenuation?
The opposite of attenuation is amplification. Amplification involves increasing the strength or intensity of a signal, sound, or electrical current, while attenuation involves decreasing it.
What is the difference between crosstalk and attenuation?
Crosstalk is the unwanted interference or signal coupling between adjacent communication channels, resulting in signal distortion or loss. Attenuation is the reduction in signal strength as it travels through a medium, such as a cable or air, leading to a decrease in signal amplitude over distance. Essentially, crosstalk involves interference between signals, while attenuation involves the weakening of a signal.
What is the difference between white noise and gaussian noise?
White noise is a type of signal that has a flat power spectral density across all frequencies, meaning that all frequencies have equal power. Gaussian noise refers to noise with a normal distribution in the time domain. While white noise has uniform power across all frequencies, Gaussian noise has a distribution of values that follows the Gaussian (bell-shaped) curve.
Difference between attenuation constant and phase constant?

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).

Difference between voice and noise?
It is really a personal impression. Does a rapper makes noise or is he singing with his voice?
What is difference between voice sound noise?

In an amp What is better high or low signal to noise ratio?
Signal to noise ratio is the difference between the noise floor and the reference level.
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.
