Made Just for You: Comparing Idiographic and Standardized Measurement of Distress

Review question / Objective: The prevalence of anxiety disorders among Chinese college students during the COVID-19 epidemic. Eligibility criteria: The inclusion criteria for eligible studies are: (a) The prevalence of anxiety symptoms is reported in the article (b) The subjects of the study are Chinese college students, including overseas Chinese students (c) Anxiety symptoms are measured with standardized measurement tools (d) All studies It was carried out during the COVID-19 epidemic. We excluded the participants from non-Chinese college students, a mixed study that did not separately report the results of a group of college students, and a study that did not use standardized test tools for anxiety.

This study was designed to standardize the measurement of visual speech comprehension in order to facilitate the evaluation of a patient’s communication handicap, his basic capacity for lipreading and the benefit received through lipreading training as a clinical tool. To this end, a silent color film of four minutes' duration was used to obtain a standardized measurement of the lipreading ability of 1108 hearing-impaired subjects. The film depicts an everyday situation in which two persons, while having coffee together, speak nine sentences of varying difficulty. Item analysis reveals good consistency, and the score obtained by the individual patient corresponds well with the clinical evaluation of his lipreading ability.

Reverberation Chambers

Noise is a growing concern in the built environment. Sound absorbers are a viable option for noise treatment. However, the characterization of their absorption coefficient in standardized measurement chambers still show challenges for high accuracy as required in practice. In recent years, experimental analysis has shown that assumptions of diffuse sound fields made in well-known reverberation chambers are unfulfilled. Specifically, that sound intensities in chamber-based measurement methods are presumed to be isotropic or diffuse. Diffusion equation models have shown dramatic changes in energy flow in the presence of highly absorptive materials under test. This has been attributed to well-documented inconsistencies reported from reverberation chamber measurements across different laboratories. This work will demonstrate that the diffusion equation model is proving to be a computationally efficient and viable method for predicting sound energy flows, garnering an increasing amount of interest from the acoustical community.
