Pregunta 3 de 5

1

How else does the middle ear increase amplification?

Selecciona una de las siguientes respuestas posibles:

  • 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

What is the function of the Eustachian tube?

Selecciona una de las siguientes respuestas posibles:

  • Equalize the frequency of most sounds so that they are within the human-hearing spectrum

  • Decrease the intensity of sounds before they reach the inner ear

  • Amplify sounds before they reach the inner ear

  • Equalize pressure build-up in the ear
