The Analysis of Presbycusis Type and Lesion Location Based on Audiogram Description, Speech Audiometry, and Otoaccoustic Emission

Abstract

Background: This study aims to determine the type of presbycusis and the location of the lesion based on audiogram images, speech audiometry and Otoacoustic Emission.
 Method: This study was an observational study of 36 presbycusis patients (72 ear samples). Pure tone audiometry, speech audiometry and Otoacoustic Emission were examined to determine the most types of presbycusis and the location of the lesion. A cross-sectional descriptive research method was conducted to analyze the dynamics of the correlation between risk factors and effects by using approaching, observing or collecting data at once (point time approach). Each research subject was observed only once, and measurements were performed towards the character status or subject variables during the examination.
 Result: The results showed that presbycusis was primarily obtained in the 60-69 years age group (69.4%). And the most types of presbycusis based on the audiogram were metabolic presbycusis (36.1%). The average hearing range based on the audiogram was at a frequency of 26-40 dB or the degree of mild deafness. Most types of deafness were Sensorineural Hearing Loss (SNHL). In speech audiometry, most NPT and NDT were mild and normal deafness as much as 44.4% in NPT and 56.9% in NDT. Based on the OAE, 72 samples showed the results of the referrals. In addition, regarding the results of the audiogram, speech audiometry and OAE, the location of the lesions of all samples were in the cochlea (100%).
 Conclusion: The most common type of presbycusis based on audiogram images is metabolic presbycusis with a mild hearing loss.
