Fiber-optic sensors based on phase shift measurements are one of the most sensitive sensors at all. In general they are capable to measure various phenomena, for example displacement, rotation, temperature, acoustic pressure, liquid flow and level, strain etc. In our paper we have used interferometer configuration based on the Mach-Zehnder principle with polarization maintaining components and narrowband DFB laser operating at a wavelength of 1550 nm. In this configuration it is important to isolate the reference arm against measured phenomena and on the other hand to increase the sensitivity of the measuring arm to maximize phase shift induced by the measured phenomenon. The paper describes various measurement arrangements of measuring and reference arm and their influence on the measurement sensitivity. The obtained frequency ranges are evaluated for all mentioned combinations.

Purpose The purpose of this document is threefold: (a) review the uses of the terms “vocal fatigue,” “vocal effort,” “vocal load,” and “vocal loading” (as found in the literature) in order to track the occurrence and the related evolution of research; (b) present a “linguistically modeled” definition of the same from the review of literature on the terms; and (c) propose conceptualized definitions of the concepts. Method A comprehensive literature search was conducted using PubMed/MEDLINE, Embase, Cochrane Central Register of Controlled Trials, and Scientific Electronic Library Online. Four terms (“vocal fatigue,” “vocal effort,” “vocal load,” and “vocal loading”), as well as possible variants, were included in the search, and their usages were compiled into conceptual definitions. Finally, a focus group of eight experts in the field (current authors) worked together to make conceptual connections and proposed consensus definitions. Results The occurrence and frequency of “vocal load,” “vocal loading,” “vocal effort,” and “vocal fatigue” in the literature are presented, and summary definitions are developed. The results indicate that these terms appear to be often interchanged with blurred distinctions. Therefore, the focus group proposes the use of two new terms, “vocal demand” and “vocal demand response,” in place of the terms “vocal load” and “vocal loading.” We also propose standardized definitions for all four concepts. Conclusion Through a comprehensive literature search, the terms “vocal fatigue,” “vocal effort,” “vocal load,” and “vocal loading” were explored, new terms were proposed, and standardized definitions were presented. Future work should refine these proposed definitions as research continues to address vocal health concerns.
