Question:
The human ear canal (Fig. 13.3) is typically about 2.4 cm long, is roughly cylindrical, and is closed at one end where it is capped by the eardrum.?
(a) What is the fundamental frequency of the ear canal??
(b) Determine the range of frequencies where the ear is most sensitive (see Fig. 13.4). How does the ear canal?s fundamental frequency compare?

I consider myself to have excellent interpersonal and assessment skills with strong teaching presentation verbal and written communication
I love tutoring. I love doing it. I find it intrinsically satisfying to see the light come on in a student's eyes.
My first math lesson that I taught was when I was 5. My neighbor, still in diapers, kept skipping 4 when counting from 1 to 10. I worked with him until he could get all 10 numbers in a row, and match them up with his fingers.
My students drastically improve under my tutelage, generally seeing a two grade level improvement (F to C, C to A, for example), and all of them get a much clearer understanding!
I am committed to helping my students get the top grades no matter the cost. I will take extra hours with you, repeat myself a thousand times if I have to and guide you to the best of my ability until you understand the concept that I'm teaching you.
