92571 Filtered speech test

Name of the Procedure:

Filtered Speech Test

Summary

The Filtered Speech Test is a hearing evaluation method that assesses how well a person can understand speech when some portions of the sound are removed or "filtered out."

Purpose

The Filtered Speech Test addresses hearing and auditory processing disorders. It helps in identifying difficulties in understanding speech, especially in noisy environments. The goal is to diagnose specific hearing issues and guide appropriate treatment plans.

Indications

• Persistent difficulty understanding speech, particularly in environments with background noise
• Suspected auditory processing disorder (APD)
• Specific populations, such as those with a history of middle ear infections or learning disabilities

Preparation

• No special preparation or fasting is required.
• The patient may be asked to complete a brief medical and auditory history questionnaire.
• Basic hearing tests may be conducted prior to the Filtered Speech Test.

Procedure Description

1. The patient is seated comfortably in a soundproof room.
2. Headphones are placed over the patient's ears.
3. The patient listens to a series of spoken words or sentences presented with portions of the signal removed or distorted.
4. The patient is asked to repeat what they hear.
5. The audiologist records the responses and analyzes the results.

Tools and Equipment:

• Audiometer
• Headphones
• Soundproof booth

Anesthesia/Sedation:

• None required

Duration

The procedure typically takes about 30-45 minutes.

Setting

The test is usually performed in an outpatient clinic or an audiology test center.

Personnel

• Audiologist or trained hearing specialist
• Audiology technician (if necessary)

Risks and Complications

• The procedure is non-invasive and carries minimal risk.
• Potential discomfort from wearing headphones for an extended period.

Benefits

• Accurate diagnosis of specific hearing and auditory processing issues.
• Tailored treatment strategies for improved communication abilities.
• Results are typically available immediately after the test.

Recovery

• No recovery time is needed; the patient can return to normal activities immediately.
• Further audiology consultations may be scheduled based on test results.

Alternatives

• Standard hearing tests (audiometry)
• Speech-in-noise tests
• Central auditory processing tests

Pros of Alternatives:

• May provide a broader assessment of hearing capabilities.
• Less specialized, more widely available tests.

Cons of Alternatives:

• May not identify specific auditory processing issues as effectively as the Filtered Speech Test.

Patient Experience

• The patient may feel brief frustration if they find the filtered speech challenging to understand.
• Minimal discomfort from wearing headphones.
• Comfort measures include breaks during the test if needed. Pain is not usually associated with this procedure.
