1. Distortion Product Otoacoustic Emissions (DPOAEs) In Tinnitus Patients
Abstract Introduction Tinnitus is the perception of sound in the absence of external sound stimulation. There is a general agreement that it is a direct consequence of irreversible and permanent cochlear damage. Objectives The present work is designed to study the distortion product otoacoustic emissions (DPOAEs) in tinnitus patients with normal hearing in

2. Effectiveness of galvanic vestibular evoked myogenic potential for evaluation of Meniere’s disease
Abstract Objectives: Although the cause of Meniere’s disease (MD) is not fully understood, endolymphatic hydrops is widely believed to be responsible for MD. Previous studies have used Air-Conducted Sound (ACS)-induced Vestibular Evoked Myogenic Potentials (VEMPs) to evaluate otolithic function in patients with MD. However, the use of Galvanic Vestibular

5. Open legacy soil survey data in Brazil: geospatial data quality and how to improve it
ABSTRACT: Spatial soil data applications require sound geospatial data including coordinates and a coordinate reference system. However, when it comes to legacy soil data we frequently find them to be missing or incorrect. This paper assesses the quality of the geospatial data of legacy soil observations in Brazil, and evaluates geospatial data sources (surv

7. Savitzky-Golay Filter for Denoising Lung Sound
ABSTRACT For computerized analysis of respiratory sounds to be effective, the acquired signal must be free from all the interfering elements. Different forms of noise which can degrade the quality of lung sounds are recording artifacts, power line/Radio Frequency (RF) interferences, ambient acoustic interferences, heart sound interference etc. Such interfere

8. Does Body Mass Index Interfere in the Formation of Speech Formants?
Abstract Introduction Studies in the fields of voice and speech have increasingly focused on the vocal tract and the importance of its structural integrity, and changes in the anatomy and configuration of the vocal tract determine the variations in phonatory and acoustic measurements, especially in the formation of the formants (Fs). Recent studies have re

11. Qualidade de vida de familiares de crianças portadoras da Síndrome de Down: perspectiva de mães
Parental expectations on an unborn child rise towards the ideal of a child in the enjoyment of good physical and mental health, which ensures its continuity. At its birth a child with Down syndrome (DS) these expectations can vanish, initiating adaptive experiences, which in some cases may be dysfunctional. This research aims to understand quality of life (Q

12. Avaliação dos ruidos articulares como diagnóstico complementar de desordens temporomandibulares / Assessment of temporomandibular joint sounds as a complementary diagnosis in temporomandibular disorders
The joint noise is commonly recognized as a sign of an articular derangement, and its analysis is part of the data set collected in many systems of classification and diagnosis, both in research and clinical activities. Despite this importance, there is some difficulty in interpreting the sounds due to the natural variability of the phenomenon, subjectivism
