it means loss of signal as distance increase July
Acoustic impedance is the measurement that indicates how much sound pressure the vibration of molecules at a given frequency is generated. Attenuation refers to the gradual loss in intensity through a medium, such as light and sound in water.
a=Power lost per unit length/2 x power transmitted
There is no attenuation due to absorption, but attenuation will occur due to divergence (spreading out) of the wave.
Attenuation means the reduction of signal strength during transmission. If one is looking for information about attenuation, it can be found on the Wikipedia website.
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.
Because race car.
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.
longer cable lengths have greater signal attenuation

AA
Attenuation typically occurs in processes involving the weakening or reduction of a signal's strength, intensity, or energy. In communication systems, attenuation can happen in transmission lines, optical fibers, or wireless channels, leading to signal loss or degradation over distance. It is essential to account for attenuation to maintain signal quality and integrity in various applications.
Attenuation is a measure of how much loss a signal experiences when it travels down a communication medium( loss as heat, absorbed by communication medium).It is mesured in decibels Attenuation is a term that refers to any reduction in the strength of a signal, when transmitting over a long dinstance. Attenuation occurs with any type of signal, whether digital or analog. It is also called loss of signals, The extent of attenuation is usually expressed in units called decibels (dBs).
