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? 7dB27.5d8 How do you know the indicated answer is accurate? Again refer back to your experiments Bone conduet ion sound is not ampliSy and only low readling ccorelec If an individual suffered from middle ear deafness, describe what would be observed by the examiner during the administration of the Rinne test 3 4 What results did your group obtain when performing the Weber test? What do these results tell you about the subject's hearing? When assessing sound localization, which of the tested locationís) was most accurate? When assessing sound localization, which of the tested locationís) was least accurate? k 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? 161 Eileen Bush William Perrotti Inquiry-Based Exercises in Human Anatomy& Physiology (Part 1)Explanation / Answer
1.air conduction
Rinne test compared perception of sound transmitted by air to those by bone conduction
3.rinne test result foe middle ear deafness patient is
Because its sensorineural loss air conduction is heard longer than bone conduction but may not be twice as long.
4.webers test
Normal hearing wi produce equal sound in both ears.
Conductive loss will cause the sound to be heard best in abnormal ear.
Sensorineural loss will cause sound to be heard best in normal ear.
5. Directly in front more accurate
Behind heads least accurate.
6. Auditory centres in brain specially turnes to each cue
Intensity and timing difference between two ears. Brain use both cues to localise sound sources.
There is cone of confusion seen in poor sound localization
