Abnormal transmission of sound through the bronchus occurs when certain areas of the lungs are consolidated or solidified. It is important to distinguish normal respiratory sounds from abnormal ones for example crackles, wheezes, and pleural. De 2025 a positive bronchophony test occurs when a patients spoken words are heard more clearly and loudly through the stethoscope during chest auscultation. Asymmetrical chest expansion, diminished breath sounds, egophony, bronchophony, and tactile fremitus can be used in combination to accurately diagnose pneumonia and pleural effusion. Bronchophony may be caused by a solidification of lung tissue around the bronchii, which may indicate lung cancer, or by fluid in the alveoli, which may indicate pneumonia.
