The continuous amplification of messages must be energized from time to time.
If not, the messages attenuate, i.e. weaken or even cease.
Attenuation coefficients are used to quantify different media according to how strongly the transmitted ultrasound amplitude decreases as a function of frequency. The attenuation coefficient () can be used to determine total attenuation in dB in the medium using the following formula:
As this equation shows, besides the medium length and attenuation coefficient, attenuation is also linearly dependent on the frequency of the incident ultrasound beam. Attenuation coefficients vary widely for different media.
The nature of relationship is prone to permeability, relationships; to be impermeable must be fortified by an uncompromising commitment, i.e. sustainable power source(s).
Here Energy and Persistence are critical as well, here, i should say that Quality and Understanding are also necessary for amplification and impermeability.
A consideration that is important to my argument is the Beer-Lambert law.
The following from the above website is important to generally understanding what I mean by Amplification/Attenuation and Permeability/Impermeability:
The law states that there is a logarithmic dependence between the transmission (or transmissivity), T, of light through a substance and the product of the
