Hearing Assessment Methods: Pure-Tone Audiometry

Pure-tone audiometry is a fundamental method for assessing an individual's hearing ability. It is widely utilized in the field of otorhinolaryngology (ENT) to diagnose various hearing impairments.

What is Pure-Tone Audiometry?

Pure-tone audiometry evaluates a person's hearing sensitivity across different frequencies using standardized tones. The test determines the softest sounds a person can hear at specific frequencies, measured in decibels (dB).

Procedure of Pure-Tone Audiometry

• The patient wears headphones or ear inserts.
• Pure tones of varying frequencies and intensities are played.
• The patient indicates when they hear a tone.
• Results are plotted on an audiogram to determine hearing thresholds.

Importance in ENT Diagnostics

Pure-tone audiometry is crucial for detecting conditions such as conductive and sensorineural hearing loss. It assists in developing appropriate treatment plans, including hearing aids or surgical interventions.

Limitations and Considerations

While highly effective, the test relies on patient cooperation and may not be suitable for infants or individuals with cognitive impairments.
