ad·ven·ti·tious lung sounds

(ad'vĕn-tish'ŭs lŭng sowndz)
Breath sounds that are not normally heard or are heard in an inappropriate place that fall into one of two categories: (1) continuous: musical sounds with a persistent pitch (e.g., wheezes, rhonchi); (2) discontinuous: nonmusical, intermittent, crackling, or bubbling sounds (rales).

adventitious lung sounds

Crackles and wheezes superimposed on the normal breath sounds; indicative of respiratory disease. Most adventitious lung sounds can be divided into continuous (wheezing) and discontinuous (crackles) according to acoustical characteristics.

The proportion of patients with audible adventitious lung sounds was significantly higher among those hospitalized for [greater than or equal to] 21 days and among those who did not survive (Table 1).
Ultrasonography was most helpful in the definitive diagnosis of superficial lung abscesses where the anechoic areas containing multiple hyperechoic dots bordered distally by a broad hyperechoic capsule were readily detected but generated no adventitious lung sounds. Daily treatment with procaine penicillin for 30 days was successful in all six sheep identified with pleural/superficial lung abscesses measuring 2-8 cm in diameter; only one of two sheep with more extensive lesions recovered.
Other difficulties include a lack of standardization in the terms used to identify adventitious lung sounds (Wilkins, Hodgkin, & Lopez, 2004) and the challenge for health care providers in recognizing and interpreting heart sounds (Wilkins et al.).
