Whisper Test Overview
The whisper test is a simple, accurate bedside screening tool for detecting hearing loss, performed by standing 2 feet behind the patient and whispering specific words or phrases while the patient occludes the non-tested ear, with failure to repeat at least 50% of whispered content indicating likely hearing impairment requiring formal audiometry. 1
How to Perform the Test
Setup and Positioning
- Stand 2 feet (approximately 60 cm) behind the patient to prevent lip reading
- Have the patient occlude the non-tested ear by placing their finger in the ear canal and moving it in a circular motion to create masking noise
- Test each ear separately
Whispered Content Selection
The examiner should whisper specific words or phrases. Research demonstrates that certain phrases show superior accuracy:
- Single words: "shoe" or "window" (AUC = 0.917-0.918) 2
- Short phrases: "it looks like it's going to rain" or "the bus is late" (AUC = 0.900-0.911) 2
Critical Technical Consideration - Examiner Experience Matters
Experienced whisperers produce whispers 8-10 dB more intense than inexperienced examiners, which significantly affects test accuracy 3. This means:
- Experienced examiners detect hearing loss at 40 dB HL threshold with 63% sensitivity and 93% specificity
- Inexperienced examiners should use a lower threshold (29 dB HL) but achieve 80% sensitivity with only 52% specificity 3
Common pitfall: Inconsistent whisper intensity is the primary source of test variability. Consider voice measurement training for inexperienced practitioners to standardize technique 3.
Interpreting Results
Positive Test (Abnormal)
Patient fails to correctly repeat at least 50% of the whispered words/phrases 4
- This indicates likely hearing impairment requiring formal pure-tone audiometry
- Positive likelihood ratio: 3.0-5.1 1
Negative Test (Normal)
Patient correctly repeats the majority of whispered content
- Negative likelihood ratio: 0.03-0.52 (excellent for ruling out hearing loss) 1
Test Accuracy
Adult Populations
- Sensitivity: 90-100% for detecting hearing loss 4
- Specificity: 70-87% 4
- Comparable accuracy to more complex screening methods like questionnaires (HHIE-S) or handheld audiometers 1
Pediatric Populations
- Sensitivity: 80-96% (notably lower than adults)
- Specificity: 90-98% 4
Important caveat: The whisper test shows some concern for lower sensitivity in children and overall reproducibility issues, particularly in primary care settings where examiner experience varies 4.
Clinical Context and Next Steps
When Positive
Refer for comprehensive audiometric evaluation including:
- Pure-tone audiometry (air and bone conduction)
- Speech audiometry
- Tympanometry
- Acoustic reflex testing 5
Pure-tone audiometry remains the gold standard and is essential to determine severity, type (sensorineural vs. conductive), and ear-specific characteristics of hearing loss 5.
Advantages Over Other Screening Methods
- No equipment required (unlike handheld audiometers)
- Quick to perform (under 2 minutes)
- Nearly equivalent accuracy to more resource-intensive methods 1
- Low cost with minimal training requirements 1
Key Limitation
Access to audiometry confirmation may be limited - 56.6% of US counties lack audiologists, disproportionately affecting older and lower-income adults 5. In such settings, the whisper test becomes even more valuable as an initial screening tool to prioritize referrals.
