The phrase "attenuation rate" is correct and usable in written English.
It can be used in contexts related to physics, telecommunications, or signal processing, where it refers to the reduction in strength of a signal as it travels through a medium.
Example: "The attenuation rate of the fiber optic cable affects the quality of the transmitted data over long distances."
Alternatives: "signal loss rate" or "diminution rate".
The distance, where the amplitude is zero, is estimated to be about 800 km from their attenuation rate if we assume that the amplitude is linearly attenuated.
The results showed that the attenuation rate of BDE-99 increased with nitrate concentrations.
Favourable comparisons are made between the predicted and measured axial attenuation rate and phase speed.
The attenuation rate surpasses 5 dB/m at certain frequency bands.
EXPERIMENTAL results1 show that the attenuation rate of extremely-low frequency radio waves decreases with decreasing-frequency in the range from a few kc/s to about 70 c/s, below which it appears to increase again.
When coincidence occurs, the axial modal attenuation rate drops sharply, allowing the exact determination of the coincidence frequency by locating the local minimum of the modal spatial attenuation rate with increasing frequency.
Maximum water level attenuation rates are, again, significantly slower (e.g. P90high maximum water levels attenuate at a rate of 1 m per 16.75 km, P85high maximum water levels attenuate at a rate of 1 m per 64 km) than rates shown by Leonard et al.30 in Samoa (maximum water levels attenuate at a rate of 1 m per 0.4 km).
Similar to runup attenuation rates, site specificity appears to be significant and detailed attention must be paid to geomorphology when considering transferring attenuation rates between sites.
For both seasons, attenuation rates across S. pacifica were the highest and were greater than published attenuation rates across similar (Spartina alterniflora) salt marshes for the comparable depths.
For example, a field study in a large salt marsh along the Western Scheldt estuary in The Netherlands measured surge attenuation rates from 5 cm/km to 70cm/km300.
The gradients or attenuation rates for each scenario however, show a linear correlation to wave height parameters at the 100 depth contour (e.g. for Hmax, R2 = 0.95), indicating that overall runup attenuation rates may be predicted well, however runup values are more erratic.
