The purpose of the present study was to examine the effect of acute Whole Body Vibration (WBV) on static and dynamic balance in physical education students. A total of 30 healthy physical education students participated in this study. The participants were divided into two groups as the Control Group (n = 15) and the Whole Body Vibration group (n…

When a stethoscope is placed on the chest over the heart, sounds coming from the heart can be directly heard. These sound vibrations can be captured through a microphone and the electrical signals from the transducer can be processed and plotted in a phonocardiogram. Students can easily use a microphone and smartphone to capture and analyse…

Purpose: School-teachers have become a benchmark population for the study of occupational voice use. A decade of vibration-dose studies on the teacher population allows a comparison to be made between specific dose measures for eventual assessment of damage risk. Method: Vibration dosimetry is reformulated with the inclusion of collision stress.…

Purpose: This study explored the effect of whole-body vibration (WBV) using accelerations of 2.56 "g" to 7.68 "g" on lower-body detraining. Methods: All participants (N = 20) were trained using a lower-body resistance-training program for 30 min twice per week from Week 0 to Week 6. At the end of the program, they were randomly…

Purpose: The aim of the present study was to qualitatively and quantitatively characterize vocal fold vibrations in sulcus vocalis by high-speed digital imaging (HSDI) and to clarify the correlations between HSDI-derived parameters and traditional vocal parameters. Method: HSDI was performed in 20 vocally healthy subjects (8 men and 12 women) and…

Sound is typically thought of something that is heard. Can it be seen or felt? Most students experience the noises that surround them in everyday life, but few stop to think about what sound is, how it travels, and the biological challenges associated with perceiving sound. Since students are already familiar with everyday sounds, inquiry-based…

Wave physics phenomena can be observed in everyday life and represent a fundamental prerequisite to many domains of classical and modern physics. Lots of studies demonstrate that novices have to face important learning difficulties in approaching this topic. The study of string vibrations' modes allows an educational introduction to basic…

Purpose: Vocal fold asymmetry creates irregular entrainments and modulations in voice, which may lead to rough perceptual quality. The presence of asymmetry can also cause mid-phonation bifurcations where a small change in the phonatory system causes a drastic change in vibration pattern, resulting in transitions in and out of rough voice. This…

This study considers the performance of tone pronunciation and morpheme intelligibility by L2 Polish Mandarin learners. A mixed-effects ordinal regression model and Tukey's HSD multiple test were used to examine the start-point, end-point, of syllables as a means of assessing their intelligibility by L2 Polish learners regarding the tones with the…

Two stay two stray cooperative model (TS-TS) has been applied to know the activity and progress of student learning outcomes in Yapis Manokwari Senior High School. The type of research used is quantitative with quasi-experimental method. Time series design research was used, in this case, the group used for research cannot be selected at random.…

Although acoustics examples and demonstrations can be an effective tool for engaging students in introductory physics classes and outreach, teaching principles of sound and vibration to the deaf and hard of hearing needs to be approached carefully. The deaf and hard of hearing have less intuition with sound but are no strangers to some of the…

A physical model has been designed to help students visualize concepts involved when solving infrared spectra. The physical model uses balls and springs to incorporate the harmonic oscillator model and Hooke's law to study dynamic vibrations within diatomic molecules. Various concepts are addressed with the model to abstract principles about how…

Infrared (IR) spectroscopy is a vibrational spectroscopic technique useful in chemical, pharmaceutical, and forensic sciences. It is essential to identify chemicals for reasons spanning from scientific research and academic practices to quality control in companies. However, in some university degrees, graduate students do not get the proficiency…

Purpose: The purpose of this study was to determine the vocal fold structural and vibratory symmetries that are important to vocal function and voice quality in a simulated paramedian vocal fold paralysis. Method: A computational kinematic speech production model was used to simulate an exemplar "voice" on the basis of asymmetric…

The development of communication, perception, sound, and rhythm (DCPSR) is a learning subject that provides stimulation, and intervention for the appreciation of sound which is done intentionally or unintentionally so that the remnants of hearing and the feeling of vibration possessed by students with hearing impairment can be used as well as…
