What Causes High-Pitched Whistling Sound While Breathing
“VO: "You hear a sharp, high-pitched whistling sound every time someone takes a breath! Why does this alarming internal noise happen?" VO: "This abnormal, high-pitched breathing sound is called STRIDOR. It occurs when turbulent airflow passes through a narrowed or partially obstructed airway." VO: "Airflow becomes restricted in the larynx or trachea. This physical response signals that your respiratory pathway is currently lacking optimal space." VO: "Have you ever heard this strange whistling sound during a cold? Drop a 'YES' in the comments and hit SUBSCRIBE!"”
Summary
Stridor is an abnormal, high‑pitched, whistling sound heard primarily during inspiration when turbulent airflow passes through a narrowed upper airway, such as the larynx or trachea. It results from partial obstruction caused by edema, secretions, or other blockages and can be heard during illnesses like a cold. The VO description correctly reflects these medical facts.

It is distinguished from other sounds by its intensity in the neck more so than the chest, timing (inspiratory), and pitch (high). Like wheezes, stridor is produced by airway narrowing, but only in the upper airways.
