COMD 5070 – 100+ Solved Questions 2025/2026 – Velopharyngeal Function, Nasometry, Speech Aerodynamics, Subglottal Pressure, PTP & Vocal Disorders

This expertly structured exam review for COMD 5070 Exam 3 (2025/2026) features 100+ solved questions centered around velopharyngeal mechanisms, speech aerodynamics, pressure-flow relationships, and instrumentation. The content aligns with advanced coursework in speech science and communication disorders, ideal for graduate-level students preparing for assessments, clinical application, or board exams. Covered domains include: Velopharyngeal function and resistance: oral vs. nasal airflow, leakage patterns, resonance, and disorders affecting port closure Measurement instruments: nasometer (nasalance tracking), pressure transducers, x-ray microbeam, fluoroscopy, EMG, oronasal mask Speech aerodynamics: oral pressure, nasal flow, subglottal pressure (Psub), intraoral pressure (Pio), phonation threshold pressure (PTP) Voice physiology: airflow rates in healthy vs. disordered voices (e.g., vocal fold paralysis, vocal hyperfunction), laminar vs. turbulent airflow Pressure-flow relationships: Ohm’s Law in speech (E=IR), resistance as vocal fold adduction, estimation of subglottal pressure Instrumentation usage: pneumotachograph, esophageal transducers, U-tube manometers Clinical implications: nasal air emission, nasalance scores for speech sounds (/m/, /n/, vowels), aerodynamic changes in vocal pathologies Each Q&A item provides concise, exam-aligned definitions and accurate application of principles for use in both theoretical and clinical settings. Emphasis is placed on both conceptual mastery and instrumental interpretation. Recommended for students in: Graduate Communication Sciences and Disorders (CSD) programs Speech-Language Pathology (SLP) licensure and board preparation Voice science, resonance disorders, and instrumentation courses Clinical settings involving nasometry, aerodynamics, or voice assessment This guide supports learners in mastering the science behind airflow, pressure, and resistance in speech production, with a clear focus on instrumentation and diagnostics.
