![]() The increase in the resonance of voice heard while auscultating is called egophony. This phenomenon is called egophony-e or a positive egophony. While listening to the breath/lung sounds with the help of a stethoscope, the person is asked to say the vowel “e.” In a normal and healthy person with a healthy lung, the same “e” sound or “beet” is heard. This leads to the production of a distinctive nasal sound. There is an increase in transmission of high-frequency sounds across the fluid around the lungs in abnormal lung tissue, and the low-frequency sounds are masked. Conditions like lung consolidation and fibrosis lead to egophony. We can hear the increase in the resonance of voice while auscultating which is egophony. Bronchphony can also be due to the solidification of the tissue around the lungs or due to wide bronchi. This positive bronchophony test is associated with lung consolidation when there is an increased density of the lung tissue due to fluid accumulation, i.e., blood or mucus. If we hear this sound is clearly while auscultation, then the bronchophony test is positive. To perform the bronchophony test, the patient utters the word ninety-nine repetitively. It is a sign of an abnormality in the lungs where the sound is transferred through the lungs and bronchi. In a healthy person, bronchophony is absent. In a healthy state, the bronchophony is to be negative, i.e., when the patient says the word 99, the sound should be faint. If the patient is healthy, the result of auscultation will be that we will hear this voice as a muffled sound. The patient is asked to say the word “ninety-nine” in his normal voice to perform the bronchophony test. In the state of health, this sound is masked or very diminished. Bronchophony – Healthyīronchophony is an abnormal condition in which the sound transfers abnormally through the bronchi and lungs. These diminished sounds can occur due to the accumulation of some fluid or air around the lungs. The vesicular diminished lung sounds are less sturdy and full than vesicular sounds. These patients show vesicular diminished breathing or vesicular diminished breath/lung sounds. In old age, breathing becomes more shallow.Ī less volume of air moves through the airway of elderly patients. This is most common in people of old age. These also have less density as compared to the vesicular sounds. It is one of the intermediate lung sounds. ![]() This site is protected by reCAPTCHA and the Google Privacy Policy and Terms of Service apply.As the name indicates, the vesicular diminished lung sounds are of a low pitch than the vesicular sounds.

These secretions can often be cleared with a good strong cough. Things that cause rhonchi include COPD, pneumonia, cystic fibrosis, bronchiectasis, and chronic bronchitis. Rhonchi happens when there are secretions in the larger airways that literally rattle around when you breathe. It’s that rattling, snoring sound that you can often feel inside your lungs. If you have ever had a lower respiratory infection, chances are you’ve experienced rhonchi. Biphasic stridor is heard when there is narrowing cartilage just below the vocal cords. In most cases, stridor can be treated and rather quickly reversed with mediations such as inhaled racemic epinephrine which helps relax and reduce swelling. Inspiratory stridor indicates a blockage of some sort that is above the vocal cords. Expiratory stridor indicates a blockage in the trachea (windpipe). There are three different types of stridor: inspiratory (when you breathe in), expiratory (when you breathe out), and biphasic (when you breathe in and out). It can be heard in all lung fields or just part of the lung, such as the bases. When the airways are severely narrowed, wheezing can be heard when you breathe in as well. This happens when the airways are narrowed due to bronchospasms and/or inflammation. Wheezing is generally a higher-pitched whistling sound that occurs most commonly when you breathe out. While not all people with asthma wheeze, the majority do. ![]() This is the most commonly heard breath sound associated with asthma. Types of lung sounds associated with asthma Wheezing ![]() I wanted to take some time to explore some of the most common abnormal breath and lung sounds in asthma that we can hear with a stethoscope and oftentimes without as well. Words that have become second nature to us sound like complete gibberish to others. You have more than likely heard some of these words used by either your doctor, respiratory therapist, or nurse when describing what your lungs sound like. Medical professionals often use words that the general public doesn’t understand.
