Phonocephalography: a non-invasive diagnostic technique. Normal vascular sounds.

Area of Science:

• Medical Diagnostics
• Acoustic Engineering
• Neuroscience

Background:

• Tinnitus and intracranial angiology require effective diagnostic tools.
• Non-invasive methods are preferred for patient safety and comfort.
• Phonocephalography offers a novel approach to auditory head-surface sound analysis.

Purpose of the Study:

• To introduce and describe the technique of phonocephalography.
• To present baseline recordings of normal phonocephalography.
• To explore its potential as a diagnostic method.

Main Methods:

• Phonocephalography involves amplifying and recording sounds from the head's surface and cavities.
• Standardized procedures were used for sound acquisition.
• Recordings focused on identifying normal physiological head sounds.

Main Results:

• This article provides a comprehensive set of normal phonocephalography recordings.
• Distinct sound patterns characteristic of normal head acoustics were identified.
• The study establishes reference data for healthy individuals.

Conclusions:

• Phonocephalography is a promising non-invasive diagnostic technique.
• Normal phonocephalography recordings serve as a crucial baseline.
• Further research is warranted to validate its clinical applications in tinnitus and angiology.
