Speech audiometry threshold; with speech recognition
CPT4 code
Name of the Procedure:
Speech Audiometry Threshold with Speech Recognition; also known as Speech Audiometry Test (SAT) or Speech Reception Threshold (SRT) Test.
Summary
In layman's terms, a Speech Audiometry Threshold Test with Speech Recognition measures an individual's ability to hear and understand speech. It involves listening to spoken words at different volumes and identifying them correctly.
Purpose
The test addresses hearing impairments and helps to determine the clarity and volume at which a person can understand speech. The goals are to diagnose hearing loss, assess the effectiveness of hearing aids, and guide treatment plans.
Indications
The procedure is typically indicated for:
- Individuals experiencing difficulty understanding speech.
- Patients with a known or suspected hearing impairment.
- Those who are being fitted for hearing aids.
- Part of a comprehensive audiological evaluation.
Preparation
- No special preparation is generally needed.
- Patients may be advised to avoid loud noises for 24 hours before the test.
- Inform the audiologist of any ear infections or ear-related issues.
Procedure Description
- The patient sits in a soundproof room and wears headphones.
- The audiologist presents words or sentences through the headphones at varying volumes.
- The patient repeats the words or sentences they hear.
- This process helps determine the softest level at which the patient can understand speech (Speech Reception Threshold) and the ability to recognize and repeat back words correctly (Speech Recognition Score).
- Tools used include audiometers and calibrated speech recordings or live voice.
Duration
The procedure typically takes about 30 to 60 minutes.
Setting
The test is performed in an audiology clinic or a specialized hearing center.
Personnel
The healthcare professionals involved include an audiologist and possibly an audiology technician.
Risks and Complications
There are minimal risks associated with this non-invasive procedure. Rarely, patients might experience:
- Mild discomfort from the headphones.
- Temporary fatigue or frustration during testing.
Benefits
- Accurate determination of hearing ability and speech understanding.
- Helps in tailoring hearing aids or other auditory therapies.
- Immediate results are often provided post-test.
Recovery
- No recovery time is needed.
- Patients can resume normal activities immediately after the test.
- Follow-up appointments may be scheduled based on the results.
Alternatives
- Pure-tone audiometry: measures hearing sensitivity using tones.
- Tympanometry: assesses the middle ear function.
- Otoacoustic emissions (OAEs): tests inner ear response.
Patient Experience
During the procedure, patients will hear varying levels of speech and are required to listen attentively and repeat what they hear. This is generally not painful, and breaks can be taken if the patient feels fatigued. Comfort measures include properly fitted headphones and a calm, quiet testing environment.
