Summary
The RBH scale demonstrates high interrater reliability for assessing hoarseness in running speech, making it a suitable clinical tool for voice quality evaluation.
Area of Science:
- Speech and Hearing Sciences
- Clinical Linguistics
Context:
- Auditory perceptual assessment is crucial for evaluating dysphonic voices in clinical settings.
- The GRBAS scale and its analogues are commonly used for voice quality assessment.
- Interrater reliability (IRR) is a critical factor for the clinical applicability of voice assessment tools.
Purpose:
- To investigate the interrater reliability (IRR) of the four-point RBH (roughness, breathiness, hoarseness) scale for perceptual voice quality assessment.
- To determine the suitability of the RBH scale for clinical application in evaluating hoarseness in running speech.
Summary:
- A study involving 78 patients reading a standard text evaluated by 19 speech and voice therapy students.
- The RBH scale was used to assess roughness, breathiness, and hoarseness.
- Reliability analysis revealed a high IRR with Cronbach's alpha of 0.94, indicating no single rater's contribution could be removed without reducing reliability.
Impact:
- The findings indicate that perceptual assessment of hoarseness in running speech using the RBH scale is highly reliable.
- The RBH scale is deemed suitable for clinical purposes and should be considered as a valuable outcome measure in voice therapy.

01:31Hearing
When we hear a sound, our nervous system is detecting sound waves—pressure waves of mechanical energy traveling through a medium. The frequency of the wave is perceived as pitch, while the amplitude is perceived as loudness.
01:17Pulse amplitude and quality
Pulse amplitude is a crucial indicator of cardiac health because it provides valuable insights into the strength of left ventricular contractions and the overall uniformity of blood circulation within the vasculature. The strength of the pulse is directly related to the force with which the heart contracts and the volume of blood being pumped.
A weak or absent pulse may indicate reduced cardiac output or poor left ventricular contraction, which can be signs of cardiovascular dysfunction or...

01:29Assessment of Ventilation II: Respiratory Depth and Rhythm
Respiratory Depth
Respiratory depth measures the volume of air inhaled or exhaled during a breath. It can vary from shallow to deep and typically remains consistent when a person is at rest or asleep. Occasionally, individuals will automatically inhale deeply, known as sighing, which inflates the lungs with more air than normal breathing.
To assess respiratory depth, observe the degree of chest excursion or movement:

01:28Physical Assessment of the Respiratory Tract IV: Auscultation
Auscultation is a crucial component of the physical assessment of the respiratory tract. It offers valuable insights into airflow through the bronchial tree and potential lung obstructions. This process involves careful listening to breath, voice, and adventitious sounds, which can reveal a wealth of information about a patient's respiratory health.
Breath Sounds
Breath sounds are categorized into vesicular, bronchovesicular, and bronchial.

01:17Auditory Perception
The auditory system is essential for sound perception, utilizing various critical structures. When sound waves enter the outer ear, they travel through the ear canal and cause the eardrum to vibrate. These vibrations are then transmitted to the middle ear, where three tiny bones – the malleus, incus, and stapes – amplify the sound. This amplification is crucial, as it ensures that the sound vibrations are strong enough to be conveyed to the inner ear. These vibrations then reach the cochlea, a...
01:25Assessment of the Cardiovascular System IV: Auscultation
Cardiac auscultation is a clinical skill used to assess heart function and detect abnormalities. It involves listening to heart sounds at specific anatomical locations through a stethoscope.
Normal Heart Sounds
S1 (First Heart Sound)-
S1 is made by the closure of the mitral and tricuspid valves (atrioventricular valves), marking the beginning of systole.
S2 (Second Heart Sound)-
S2 is made by the closure of the aortic and pulmonic valves (semilunar valves), marking the end of the systole.
