Question

1 Which mechanism of sound conduction is able to detect softer, less intense sounds? Air conduction Bone conduction Defend your answer using your experimental results 2 During a Rinne test readings of 7dB and 27.5 dB were recorded. Note: Decibels are a measure of loudness Which of the two recorded readings most likely indicates bone conduction? 7d8 27.5dB How do you know the indicated answer is accurate? Again refer back to your experiments. 3 If an individual suffered from middle ear deafness, describe what would be observed by the examiner during the administration of the Rinne test. 4 What results did your group obtain when performing the Weber test? What do these results tell you about the subject's hearing? 5 When assessing sound localization, which of the tested location(s) was most accurate? When assessing sound localization, which of the tested location(s) was least accurate? 6 Think about the locations that the subject had the most difficulty localizing. What did these locations have in common with one another? How did this common characteristic contribute to poorer accuracy by the subject?

Explanation / Answer

Q 1 answer is air conduction detect soft sound, less intense sound because in air conduction sound is amplified by 22 times in middle ear so in normal ear air conduction better than bone conduction.

2.

Bone conduction is indicated by low decibel sound which is 7 db, because in bone conduction sound is not amplify and only low reading recorded.

3. In case of middle ear deafness rinne test is negative because in middle ear deafness air conduction is absent and only bone conduction present, & BC is greater than AC.

So rinne test is negative

In normal healthy people rinne test is positive.

4.

In weber test best assessment is -

Weber goes away from sensorineural hearing loss.

And weber goes towards the conductive hearing loss.

5. Most accurate location for sound assessment is at vertex in the midline of face.

And least accurate is any side away from midline.
