Final answer:

Sibilant and sonorous rhonchi are breath sounds caused by airway narrowing, while crackles result from different causes.


Explanation:

Sibilant rhonchi and sonorous rhonchi are abnormal breath sounds caused by narrowing of the airways. Sibilant rhonchi are high-pitched wheezing sounds that occur when there is partial obstruction in the smaller airways, while sonorous rhonchi are low-pitched snoring or rattling sounds that happen in larger airways due to mucus accumulation or narrowing.

Course crackles and fine crackles, on the other hand, are caused by abnormal air movement through fluid in the airways or tiny airways popping open during inhalation, respectively, and are not directly related to narrowing of the airways.
