Acoustic rhinometry
Acoustic rhinometry is a rapid, non-invasive otolaryngology test that measures nasal cavity cross-sectional area and volume from reflected sound pulses, used to assess nasal obstruction, including in children.
Electroglottography
Electroglottography (EGG) is a noninvasive, low-cost technique that measures changes in the contact area of the vibrating vocal folds using electrodes on the neck, used in voice clinics, phonetics, and singing pedagogy.
Otoscopes
Otoscopes (auriscopes) are hand-held instruments with a light, ear speculum, and magnifying lens for examining the ear canal and tympanic membrane; first integrated by Bruton in 1862, class I FDA-exempt, with pneumatic and digital telemedicine variants.
Otoscopy
Otoscopy is a clinical examination using an otoscope, combining light, speculum, and magnifying lens, to inspect the ear canal and tympanic membrane and diagnose ear conditions.
Pneumatic otoscopy
Pneumatic otoscopy is a diagnostic examination in which a pneumatic otoscope puffs air against the eardrum to judge its movement, directly testing for middle ear effusion.
Rhinomanometry
Rhinomanometry is a diagnostic technique measuring nasal airflow and pressure simultaneously to quantify nasal airway resistance in Pa/cm³/s, most often by active anterior rhinomanometry.
Speech audiometry
Speech audiometry is a clinical hearing test measuring how well a listener detects and understands speech rather than pure tones, using the speech recognition threshold and word recognition score.
