Tactile fremitus, known by many other names including pectoral fremitus, tactile vocal fremitus, or just vocal fremitus, is a vibration felt on the patient's chest during low frequency vocalization. [ 6 ] : 409 Commonly, the patient is asked to repeat a phrase while the examiner feels for vibrations by placing a hand over the patient's chest or ...
In UK bronchophony is often called "vocal resonance" and is similar to "tactile vocal fremitus" (TVF); the difference being that in TVF the sensor is the edge of the hand. All three - whispering pectoriloquy, TVF and vocal resonance - fulfill the same purpose, to distinguish between consolidation and pleural effusion, both of which cause ...
A lack of normal breath sounds or the presence of crackles can indicate fluid consolidation. Increased vibration of the chest when speaking, known as tactile fremitus, and increased volume of whispered speech during auscultation can also indicate the presence of fluid. [14] Several tests can identify the cause of CAP.
A pleural effusion is accumulation of excessive fluid in the pleural space, the potential space that surrounds each lung.Under normal conditions, pleural fluid is secreted by the parietal pleural capillaries at a rate of 0.6 millilitre per kilogram weight per hour, and is cleared by lymphatic absorption leaving behind only 5–15 millilitres of fluid, which helps to maintain a functional ...

Egophony (British English, aegophony) is an increased resonance of voice sounds [1] heard when auscultating the lungs, often caused by lung consolidation and fibrosis.It is due to enhanced transmission of high-frequency sound across fluid, such as in abnormal lung tissue, with lower frequencies filtered out.
