Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this descriptive study is to collect the wideband immittance data in Thai normal hearing and conductive hearing loss adults. The main questions it aims to answer are:

1. What is normative data of wideband acoustic immittance in Thai normal hearing adults
2. What is the wideband acoustic immittance data in Thai conductive hearing loss who have type A, AS and Ad tympanogram Participants will examine hearing tests consequently

* pure tone audiometry
* Tympanometry with ipsilateral acoustic reflex
* Wideband acoustic immittance
