Stridor (from Latin 'creaking/grating noise') is an extra-thoracic high-pitched breath sound resulting from turbulent air flow in the larynx or lower in the bronchial tree. It is different from a stertor, which is a noise originating in the pharynx. Stridor is a physical sign which is caused by a narrowed or obstructed airway.
The current mainstay of treatment is therapy-based. Specialist breathing techniques, most commonly termed biphasic breathing techniques or EILOBI are recommended to reduce turbulent inspiratory airflow and thus reduce chance of laryngeal closure. [18] Direct laryngeal visualisation during exercise to deliver biofeedback has been employed with ...

A wheeze is a clinical symptom of a continuous, coarse, whistling sound produced in the respiratory airways during breathing. [1] For wheezes to occur, part of the respiratory tree must be narrowed or obstructed (for example narrowing of the lower respiratory tract in an asthmatic attack), or airflow velocity within the respiratory tree must be heightened.
Stertor (from Latin stertere 'to snore') is a term first used in 1804 [2] to describe a noisy breathing sound, such as snoring. [3] [4] It is caused by partial obstruction of the upper airways, at the level of the nasopharynx or oropharynx.
Biphasic (or diphasic, bifurcated, or bimodal) sleep refers to two periods, while polyphasic usually means more than two. [1] Segmented sleep and divided sleep may refer to polyphasic or biphasic sleep, but may also refer to interrupted sleep , where the sleep has one or several shorter periods of wakefulness, as was the norm for night sleep in ...
Psychophysiology measures exist in multiple domains; reports, electrophysiological studies, studies in neurochemistry, neuroimaging and behavioral methods. [5] Evaluative reports involve participant introspection and self-ratings of internal psychological states or physiological sensations, such as self-report of arousal levels on the self-assessment manikin, [6] or measures of interoceptive ...
Psychoacoustics is the branch of psychophysics involving the scientific study of the perception of sound by the human auditory system.It is the branch of science studying the psychological responses associated with sound including noise, speech, and music.
