Examination Methods
1. Age-Specific Assessment Techniques
- Newborns (0-1 month):
- Automated ABR screening
- OAE screening
- Startle reflex observation
- Infants (1-6 months):
- Behavioral observation audiometry

- OAE testing
- Toddlers (6-24 months):
- Visual reinforcement audiometry
- Conditioned play audiometry
- Tympanometry
- Preschool (2-5 years):
- Play audiometry
- Speech discrimination testing
- Pure tone screening
2. Otoscopic Examination
- External Ear Assessment:
- Pinna position and appearance
- External canal patency
- Cerumen presence
- Signs of infection
- Tympanic Membrane Evaluation:
- Color and transparency
- Light reflex
- Landmark identification
- Mobility (with pneumatic otoscopy)
3. Objective Tests
- Tympanometry:
- Middle ear pressure
- Tympanic membrane compliance
- Ear canal volume
- Type classification (A, B, C)
- OAE Testing:
- DPOAE measurements
- TEOAE screening
- Response analysis
4. Behavioral Tests
- Sound Localization:
- Lateral sound awareness
- Vertical plane localization
- Distance perception
- Speech Testing:
- Age-appropriate word recognition
- Speech discrimination
- Language development assessment
Clinical Protocol
- Pre-examination Steps:
- Equipment calibration check
