QUESTIONS REGARDING THE AUDITORY SYSTEM:
Different instruments sound different playing the same note because. O They don't sound different if they're playing the same note They are playing at different amplitudes The same note is at different frequencies from different instruments The sounds differ in complexity QUESTION 2 Corey is putting together his own fireworks and wants to make the loudest possible bang. Despite the fact that Corey is an idiot, what is the loudest sound he could make? 200+ dB O 194 dB O 94 dB 20 kHz QUESTION 3 Auditory information arrives at primary auditory cortex directly from. Medial geniculate nucleus Cochlear nuclei The medial lemniscus OAuditory nerve QUESTION 4 The auditory nerve enters the head at the level of... O Cerebral cortex Brain stem O Thalamus Cervical spine QUESTION 5 Jillian has come up with a great idea for a ringtone. Since her teachers are all middle-aged, she is going to use a pure tone that they can't hear. What frequency should she use? O 500 Hz O5,000 Hz O 15,000 Hz O25,000 HzExplanation / Answer
Answer 1 - Different instruments sound different playing the same note because the same note is at different frequencies from different instruments.
Answer2 - answer will be 194 dB. It is the oldest sound in decibels which a man can produce. Any sound above 85 dB is considered as noisy.
Answer3- answer will be medial geniculate nucleus. Primary auditory cortex directly receives auditory information from medial geniculate nucleus. Auditory pathway includes, cochlear nucleus, trapezoid body, superior olivary complex, lateral leminiscus, inferior colliculi, medical geniculate nucleus, primary auditory cortex.
Answer4- the auditory nerve enters the brain at the level of brain stem, in superior olivary complex which is located in pons. Pons is part of the brain stem.
Answer 5- Answer will be 25000 Hz because the hearing range of human ear is 20 to 20000 Hz. This means that human ear can not heard sound with frequency less than 20Hz and more than 20000 Hz.
