1. Comparison of Relative Loudness Judgment in Children using Listening Devices with Typically Developing Children
Abstract Introduction Loudness perception is considered important for the perception of emotions, relative distance and stress patterns. However, certain digital hearing devices worn by those with hearing impairment may affect their loudness perception. This could happen in devices that have compression circuits to make loud sounds soft and soft sounds loud

2. Comportamento territorial, vocalização e biologia reprodutiva de Allobates olfersioides (Anura: Aromobatidae)
RESUMO Em anfíbios a territorialidade, o cortejo elaborado e outras formas de comportamento, parecem estar mais associados a espécies que exibem o padrão de reprodução prolongado. A vocalização é um importante aspecto biológico relacionado à reprodução e ao comportamento social dos anuros. Este é o primeiro estudo com comportamento e vocalizaç�

3. Sonographic patterns of Peyronie's disease in patients with absence of palpable plaques
ABSTRACT Purpose Non-palpable isolated septal plaques of the penis are likely present in a significant number of patients affected by erectile dysfunction (ED) and penile pain without deformity or curvature. The aim of this study was to evaluate the ultrasound (US) patterns observed in patients investigated for ED or penile pain without curvature. Material

4. Simultaneous prestack seismic inversion in a carbonate reservoir
Abstract We applied a method of Simultaneous Prestack Seismic Inversion (SPSI) in a hydrocarbon field located in the Campos Basin, Brazil. The goal was to study the application of this method to Albian carbonate rocks of the Quissamã Formation. Based on what is found in nearby fields, this Formation potentially contains hydrocarbon accumulations that can be

5. 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

6. Geminate attrition across three generations of Farsi-English Bilinguals living in Canada: An Acoustic Study
Abstract The main goal of this study was to determine whether the geminate-singleton consonant length contrast attrites across three different generations of Farsi-English-speaking bilinguals living in Canada. The secondary aim of the study was to shed light on the role of universal phonetic factors on the process of geminate-singleton length contrast attrit

7. Pattern Identification on the Nonlinear Radial Motion of an Oscillating Spherical Bubble Using Neural Networks
Abstract The main goal of this article is to study the oscillatory motion of a spherical gas bubble immersed in a Newtonian liquid subjected to a harmonic pressure excitation. We use the classical Rayleigh-Plesset equation to study the radial motion of the bubble undergoing a forcing acoustic pressure field. The second order nonlinear ordinary differential e

8. Cortical activity in tinnitus patients and its modification by phonostimulation
OBJECTIVE: The goal of this study was to observe spontaneous cortical activity and cortical activity modulated by tinnitus-matched sound in tinnitus patients and healthy subjects with no otoneurologic symptoms. METHOD: Data were prospectively collected from 50 tinnitus patients and 25 healthy subjects. Cortical activity was recorded in all subjects with e

9. Mechanical spectroscopy study of the Cu36Zr59Al5 and Cu54Zr40Al6 amorphous alloys
A mechanical spectroscopy study of Cu-Zr-Al bulk metallic glasses, was performed with two types of equipment: a Kê-type inverted torsion pendulum and an acoustic elastometer, working in the frequency ranges of Hz and kHz, respectively, with a heating rate of 1 K/min. The analysis of the anelastic relaxation shows similar spectra for both types of equipment

10. Acoustic analyses of diadochokinesis in fluent and stuttering children
OBJECTIVES: The purpose of the study was to acoustically compare the performance of children who do and do not stutter on diadochokinesis tasks in terms of syllable duration, syllable periods, and peak intensity. METHODS: In this case-control study, acoustical analyses were performed on 26 children who stutter and 20 agedmatched normally fluent children (bot

11. Padrões de emissão acústica em moscas-das-frutas do gênero Anastrepha (Diptera: Tephritidae) e suas implicações no isolamento reprodutivo pré-copulatório / Acoustic emission patterns in fruit flies of genus Anastrepha (Diptera: Tephritidae) and precopulatory reproductive isolation
Três tipos de sons de cortejo foram descritos para machos de tefritídeos: de chamada, na ausência de fêmeas; de aproximação, na proximidade de fêmeas; e de pré-cópula, após a monta das fêmeas pelos machos. Nas espécies do gênero Anastrepha em que foram registrados sons de acasalamento, somente dois tipos estão presentes: de chamada e de précó

12. Padrão visual da dinâmica vocal como instrumento para o diagnóstico da disfagia em pacientes com alterações neurológicas / Vocal Dynamic Visual Patterns (VDVP) for swallowing dysfunctions analysis in patients with neurological diseases
Swallowing dysfunction (dysphagia) is very common in individuals with neurological impairment. Most studies examining the presence of coughing after swallowing, and/or disorders of phonation such as hoarseness have shown that a variety of voice and laryngeal disorders can be positively related to penetration or aspiration. Although, acoustic analysis has bee
