Objectives/hypothesis: To obtain actual status of age-related hearing loss in a general unscreened population of older Dutch adults and to investigate whether the prevalence or degree has changed over time.
Study Design: To investigate the prevalence and degree of hearing loss, we conducted a large prospective cohort study of older adults between February 2011 and July 2015.
Methods: Pure-tone air- and bone-conduction thresholds were measured for 4,743 participants.
Article Synopsis
- The study examined the use of the Dysphonia Severity Index (DSI) and the Voice Handicap Index (VHI) in assessing voice disorder treatments among 171 patients.
- Both indexes showed significant improvements post-intervention, especially in patients receiving voice therapy or surgery, indicating their effectiveness in evaluating treatment outcomes.
- The DSI provides an objective measure of voice quality, while the VHI reflects the patient's perceived voice handicap, making them complementary tools in clinical practice.
Objective: The purpose of this study was to investigate the interobserver variability and the test-retest variability of the Dysphonia Severity Index (DSI), a multiparametric instrument to assess voice quality.
Methods: The DSI was measured in 30 nonsmoking volunteers without voice complaints or voice disorders by two speech pathologists. The subjects were measured on 3 different days, with an interval of 1 week.
The purpose of this study was to investigate the usefulness of the Dysphonia Severity Index (DSI) as an objective multiparametric measurement in assessing dysphonia. The DSI was compared with the score on Grade of the GRBAS scale. Investigated was also whether the DSI is related to severity of dysphonia, which was represented by different diagnosis groups.

Objective measurements such as the dysphonia severity index (DSI), using four parameters (highest frequency, lowest intensity, maximum phonation time and jitter), appear to correlate well with perceptual evaluation. The aim of this study was to investigate the influence, if any, of age and gender on the DSI.
