Karmel Sonix Ltd has developed the Personal WheezoMeter a hand-held pulmonary sounds analyzer that utilizes contact sensors to acquire, amplify, filter, record and quantify the presence of wheezing. When used to monitor conditions such as asthma, this device should be used under the direction of a physician or licensed healthcare professional. The device is intended for use with pediatric and adult patients in both home and clinical settings.
The purpose of the study is to determine whether Wz% and change in Wz% correlate with symptoms and change in symptoms at least as well as FEV1 and change in FEV1.0. Additional information to be obtained from the study will be to determine whether there is a symptom threshold at which a patient seeks rescue medications and if so, to determine the value of Wz% and FEV1.0 at this point (Wz%, FEV1.0 thresholds). The study will also provide information on the within patient and whole group correlations between Wz% and FEV.

Late-acquired sounds, such as /r/ are difficult to learn and many children experience persistent errors on these sounds. The purpose of the present study is to determine whether treating t...
The purpose of this study is to better understand the sensitivity of listeners to the fast changes in frequency or amplitude of sounds that occur in speech. The investigators are studying ...
A French physician René Laënnec invented the stethoscope for auscultation of heart and lung sounds in 1816 (1) and, more than 200 years later, the auscultation of respiratory sounds still provides e...
The objective assessment of cough frequency is essential for evaluation of cough and antitussive therapies. Nonetheless, available algorithms for automatic detection of cough sound have limited sensit...
Lung auscultation is helpful in the diagnosis of lung and heart diseases; however, the diagnostic value of lung sounds may be questioned due to interobserver variation. This situation may also impair ...
To investigate the characteristics of speech perception, we evaluated the differences in mismatch negativity (MMN) between vowel change and frequency change. Additionally, we examined the effects of g...
In everyday life, we process mixtures of a variety of sounds. This processing involves the segregation of auditory input and the attentive selection of the stream that is most relevant to current goal...
Noises, normal and abnormal, heard on auscultation over any part of the RESPIRATORY TRACT.
The sounds heard over the cardiac region produced by the functioning of the heart. There are four distinct sounds: the first occurs at the beginning of SYSTOLE and is heard as a "lubb" sound; the second is produced by the closing of the AORTIC VALVE and PULMONARY VALVE and is heard as a "dupp" sound; the third is produced by vibrations of the ventricular walls when suddenly distended by the rush of blood from the HEART ATRIA; and the fourth is produced by atrial contraction and ventricular filling.
Congenital vascular malformation in which the AORTA arch and its branches encircle the TRACHEA and ESOPHAGUS. Signs and symptoms include DYSPNEA; RESPIRATORY SOUNDS, especially with eating, DYSPHAGIA, persistent cough, and GASTROESOPHAGEAL REFLUX or may be asymptomatic. Two most common types are double aortic arch and right aortic arch. It may be associated with other anomalies (e.g., DIGEORGE SYNDROME).
A mutant strain of TRANSMISSIBLE GASTROENTERITIS VIRUS causing mild or subclinical respiratory infections in young SWINE. It may also play a role in post-weaning porcine respiratory disease complex, especially when combined with other respiratory agents.
Respiratory system manifestations of diseases of the respiratory tract or of other organs.

Asthma is caused by inflammation of small tubes, called bronchi, which carry air in and out of the lungs. If you have asthma, the bronchi will be inflamed and more sensitive than normal. When you come into contact with something that irritates your...
