Pure tone audiometry (PTA)
Enhancing Hearing Assessments with Advanced TechnologyPure Tone Audiometry (PTA) is a fundamental hearing test used in Speech and Hearing Clinics to evaluate an individual’s hearing sensitivity across different frequencies. It helps in diagnosing the type and degree of hearing loss, facilitating appropriate intervention and treatment plans. PTA is essential for both adults and children.

The Pure tone audiometry (PTA) Process
Pure Tone Audiometry (PTA) is a vital tool in Speech and Hearing Clinics for diagnosing and monitoring hearing loss. Its comprehensive approach, objective results, and clinical applications make it indispensable for effective hearing assessment and management. By providing detailed insights into an individual's hearing profile, PTA facilitates timely and appropriate interventions, enhancing the overall quality of life for those with hearing impairments.
The patient is seated in a soundproof booth to eliminate background noise that could interfere with the test. They are provided with headphones or insert earphones for air conduction testing and a bone conduction oscillator for bone conduction testing.
Procedure: The audiologist presents a series of pure tones at various frequencies (typically ranging from 250 Hz to 8,000 Hz) through the headphones or insert earphones. The patient indicates when they hear each tone by raising their hand, pressing a button.
Threshold Determination: The softest sound the patient can hear at each frequency, known as the hearing threshold, is recorded. This is done for each ear separately.
