Wheezing

Wheezes are adventitious lung sounds that can be best described as "musical," produced by airflow through the central and lower airways. 8 Wheezes have sinusoidal acoustics, over a wide frequency range, typically 100 to 1000 Hz. The duration is prolonged, typically longer than 80 ms. Wheezes differ from the other two main adventitial lung sounds: rhonchi and crackles (rales). Rhonchi are a series of damped sinusoidal sounds, of lower frequency (<300 Hz) and prolonged duration (>100 ms). Crackles are a series of intermittent individual sounds, typically of less than 20 ms duration.
