How is hearing measured during a physical examination? Comprehensive analysis of hearing testing methods and processes
Hearing health is an important part of human health, and regular hearing tests can help detect hearing problems early. This article will introduce in detail the common methods, processes and precautions for hearing testing during physical examinations, and attach recent hot topic data across the Internet for reference.
1. Recent hot topic data (last 10 days)
| Ranking | hot topics | Search volume (10,000) |
|---|---|---|
| 1 | Early signs of hearing loss | 45.6 |
| 2 | Effect of headphones on hearing | 38.2 |
| 3 | Physical examination hearing test items | 32.7 |
| 4 | Newborn hearing screening | 28.9 |
| 5 | The relationship between tinnitus and hearing | 25.4 |
2. Physical examination and hearing test methods
1.Pure Tone Audiometry (PTA)
The most basic hearing test method is to play sounds of different frequencies through headphones, and the tester will respond to pressing buttons after hearing them.
| frequency range | Test strength | Applicable people |
|---|---|---|
| 250-8000Hz | 0-120dB | adults and children |
2.Acoustic impedance test
A test to evaluate middle ear function and determine the condition of the middle ear by measuring the reflection of sound by the tympanic membrane.
| test items | normal value range | abnormal meaning |
|---|---|---|
| Tympanogram | Type A curve | Middle ear lesions |
| stapedius reflex | 70-100dB | auditory nerve problems |
3.speech audiometry
Test the ability to recognize language in a noisy environment, which is closer to real life scenarios.
| Test content | Scoring criteria | clinical application |
|---|---|---|
| Monosyllable word recognition | ≥90% normal | Hearing aid effectiveness evaluation |
| Statement recognition | ≥80% normal | central deafness screening |
3. Physical examination and hearing test process
1.preparation stage
• Avoid noise exposure for 24 hours
• Keep ear canals clean
• Remove equipment such as hearing aids
2.Testing process
| steps | time | Things to note |
|---|---|---|
| Consultation | 5 minutes | Provide hearing history |
| Otoscopy | 3 minutes | Troubleshoot ear canal blockage |
| pure tone audiometry | 15 minutes | stay focused |
| Acoustic impedance | 5 minutes | stay still |
3.Interpretation of results
There are four types of audiograms:
• Type A: normal hearing (≤25dB)
• Type B: Mild deafness (26-40dB)
• Type C: Moderate deafness (41-70dB)
• Type D: Severe deafness (≥71dB)
4. Hearing protection tips
1. Avoid using headphones for a long time, and the volume should not exceed 60%
2. Stay away from high-intensity noise environments
3. Get regular hearing checks
4. Maintain a healthy lifestyle
Conclusion:Hearing testing is an important item in physical examination. Scientific testing methods can accurately evaluate hearing status. It is recommended to have a hearing check-up once a year, especially for people who have been exposed to noisy environments for a long time or have symptoms of hearing loss. Recent data shows that public attention to hearing health continues to rise, indicating that more and more people are beginning to pay attention to this health indicator.
