Questão 3 de 5

1

How else does the middle ear increase amplification?

Selecione uma das seguintes:

  • The middle ear muscles vibrate helping sounds reverberate

  • 17:1 ratio of oval window to tympanic membrane leading to increased intenisity

  • The opening and closing of the Eustachian tube intensifies vibrations

  • The external auditory meatus is funnel shaped increasing amplitude further down
