In this lecture ´´ Assessment of Hearing ´´ is explained. Section one is about ´´ Initial Examination´´. At the start of this section, Air and Bone Conduction is explored while giving an assessment of hearing. Types of hearing loss are then explained by the demonstrator. The educator then ends the section by giving an overview of initial otoscopic examination.
Section two is about ‘Clinical Tests’’. In this section, the educator talks about the clinical tests for hearing. Firstly, finger friction and watch test is demonstrated, which is followed by the tuning fork test. Rhine test, Weber test and absolute bone conduction test is then explained in the later part of this section. Lastly, schwabach’s test and Gelle’s test are discussed.
Section three is about ‘Audiometric Tests’’. In the first slide of this section, pure tone audiometry is elaborated. The educator then focuses on the speech audiometry and SD score of hearing. The types of Bekesy audiometry and Impedance audiometry is then demonstrated. After that, tympanometry and types of tympanometry is explained, followed by the acoustic reflex.
Section four is about ‘Special Tests’’. In the start of this section, the educator talks about the recruitment and short increment sensitivity index. Threshold tone decay test is then demonstrated. Furthermore, otoacoustic emissions and types of OAEs are explained along with its uses. In the end, central auditory tests are elaborated.
Evoked Response Audiometry
Section five is about ‘Evoked Response Audiometry’’. This section begins by exploring the electrocochleography and auditory brainstem response, along with its uses. The auditory steady state response and its district features are then discussed by the educator in the end of this section.
