The phrase "alpha ratio" is correct and usable in written English.
It can be used in contexts related to finance, investment analysis, or performance measurement, typically referring to a risk-adjusted return metric.
Example: "The fund manager reported an impressive alpha ratio, indicating that the fund outperformed its benchmark after adjusting for risk."
Alternatives: "excess return" or "risk-adjusted return".
band spectrum 0 1, 0 5, and 1 5 kHz Alpha ratio (in dB), Hammarberg index (in dB) Others Equivalent sound level (in dB) Frequency with maximum amplitude in modulation spectrum of F 0 and loudness.
The alpha ratio is defined as the ratio of the energy below 1 kHz and between 1 and 5 kHz, the Hammarberg index is defined as the ratio of the highest energy peak in the 0 2 kHz region to that of the highest peak in the 2 5 kHz region [22].

Call parameters measured were call length; dominant frequency; dominant frequency of the first, second, and third part of the call; mean, minimum, maximum, and standard deviation of the harmonicity:noise ratio; formant candidates 1 5; formant dispersal; alpha ratio 1000 and 2000; and first to third peak frequency of amplitude modulation.

The QEEG results revealed increased alpha 2/alpha 1 ratio among patients with hippocampal atrophy.
Open image in new window Fig. 2 Distribution of hippocampal atrophy and alpha 2/alpha 1 ratio among the study groups.
Significant relationship was found between alpha 2/alpha 1 ratio and hippocampal atrophy among DM with MCI group in comparison to other groups (P < 0.001) (Fig. 2).
