Detailed explanation-1: -Egophony is increased resonance of voice sounds heard when auscultating the lungs. When spoken voices are auscultated over the chest, a nasal quality is imparted to the sound which resembles the bleating of a goat.
Detailed explanation-2: -Voiced sounds, such as egophony, can provide important information about the presence of a lung abnormality and its location. The basic idea is that normal lungs (filled with air), do not readily transmit sounds, while consolidated lung tissue more readily transmits sounds.
Detailed explanation-3: -The crackle, often called “rale, ‘’ sounds like the rubbing of a lock of hair over the ear. In vivo, this sound is produced by the snapping open of previously collapsed lung structures, either airways or alveoli. The timing of crackles, which invariably occur during inspiration, should be noted.
