Abstract:
OBJECTIVE:Audiometric configuration distribution of hearing loss was analyzed for public policy efforts of hearing loss prevention and rehabilitation.
METHOD:According to the archived records of the Clinical Audiology Center of Beijing Tongren Hospital, Capital Medical University, audiometric configuration distribution was analyzed by different type,degree of hearing loss and age factor.
RESULT:1. Overall audiometric configuration distribution: the percentages of "sloping", "rising", "flat", "U-shaped", and other type of audiometric configuration distributions are 52.8%, 7.6%, 15.4%, 13.2% and 11.0%, respectively. No difference was found between male and female in the audiometric configuration distribution; 2. Audiometric configuration distribution by type of hearing loss: sloping hearing loss dominants sensorineural and mixed hearing loss; 3. Audiometric configuration distribution by degree of hearing loss: sloping hearing loss dominants mild, moderate and severe hearing loss, U-shaped hearing loss dominants profound hearing loss; 4. Audiometric configuration distribution by age: for age group 5 to 7, the highest prevalence of audiometric configuration is "sloping", followed by "flat", "U-shaped", other type and "rising"; with the age increasing, the percentage of sloping hearing loss increased dramatically.
CONCLUSION:Audiometric configuration distribution shows obvious characteristic of on the type, degree of hearing loss and age factor. "sloping" hearing loss dominates the audiometric configuration.
