Resonance

(noun)

The amplication of vibration by the structures of the upper respiratory tract, which can also influence the quality or tone of the sound.

Examples of Resonance in the following topics:

  • Medical Imaging

    • A magnetic resonance imaging instrument (MRI), or "nuclear magnetic resonance (NMR) imaging" scanner as it was originally known, uses powerful magnets to polarize and excite hydrogen nuclei (single proton) in water molecules in human tissue, producing a detectable signal which is spatially encoded, resulting in images of the body scanner .
    • This is the "resonance" part of MRI.

  • Structures Used in Voice Production

    • The three basic mechanisms of voice production are air supply, vibration, and resonance.
    • Sound is produced by a combination of different structures of the respiratory system working together to create and resonate a sound.
    • Resonance: The structures of the upper respiratory tract—particularly the soft palate of the mouth, the nasopharynx, and the paranasal sinuses—resonate and amplify the vibration of the vocal folds, making the sound louder and changing its tone.

  • General Features and Functions of the Skull

    • They contribute to resonance of the voice and assist in the warming and moistening of air inhaled via the nose.

  • Paranasal Sinuses

  • Cleft Palate and Lip

    • Because of the gap, air leaks into the nasal cavity resulting in a hypernasal voice resonance and nasal emissions while talking.

  • Spinal Cord Compression

    • Diagnosis is by x-rays, but preferably magnetic resonance imaging (MRI) of the whole spine.

  • Brain Tumors

    • Brain metastasis in the right cerebral hemisphere from lung cancer shown on T1-weighted magnetic resonance imaging with intravenous contrast.

  • Nose and Paranasal Sinuses

    • Other possible sinus functions include giving resonance to the voice, supporting the structure of the skull and facial bones, heating and humidifying inhaled air, and protecting the face from injury.

  • Association Areas

    • Well-known techniques are EEG (electroencephalography), which records the brain's electrical activity, and fMRI (functional magnetic resonance imaging) , which tells us more about brain functions.

  • Structure of a Nerve

    • This increase in fluid can be visualized using magnetic resonance neurography to diagnose nerve damage.
