1. PHYSIOLOGY and METHODS of EXAMINATION of the ACOUSTIC ANALYZERS

6. The sound-perceiving part - the sound transforms into nerve impulse

13. Mixed hearing loss

17. Rinne’s test.

18. Rinne’s test – the comparison between air and bone conduction Air > Bone Air < Bone Positive - Normal Perceiving hearing loss Negative - Conductive hearing loss

19. Weber’s test.

20. Weber’s test Normal hearing Normal hearing

21. Weber’s test - lateralized to the health side Normal hearing Perceiving type of hearing loss

22. Weber’s test - lateralized to the sick side Normal hearing Conductive type of hearing loss

23. Schwabach's test.

24. Schwabach's test. Perceiving type of hearing loss Conductive type of hearing loss elongated shortened

25. The difference between two types of hearing loss Shortened Schwabach’s test Elongated Lateralization to the healthy ear Weber’s test Lateralization to the sick ear Positive Rinne’s test Negative Sensori-neural hearing loss Test Conductive hearing loss

27. Pure-tone audiometry
