Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

The method of formation of the combined masking signals for the systems of protection of speech information from the leakage on acoustic channels is validated. The combined masking signals include "white" noise in the range of frequencies from 125 to 6500 Hz and signals of outburst character (speech-like signals). Ratios between the specified types of signals are picked out from the language of the speech signal demanding protection.
