What makes hearing different from all other senses?

IT IS THE ONLY ONE THAT IS MECHANICAL, BASED ON PHYSICAL MOVEMENT

What do the ossicles do?

PIVOT IN SUCH A WAY TO AMPLIFY SOUND VIBRATIONS GOING FROM AIR TO FLUID

Decibels are a "relative measurement." What does this mean?

SOUND INTENSITY IS COMPARED TO ANOTHER SOUND TO GET AN ACCURATE MEASUREMENT

What is the "decibel scale?"

TO MEASURE SOUND INTENSITY (AMPLITUDE)

Why is it difficult for sound vibrations to travel from the outer and middle ear TO the INNER ear?

BECAUSE SOUND MUST TRANSFER FROM AIR TO THE FLUID INSIDE THE COCHLEA

What do the "hair cells" do inside the cochlea?

CONVERT SOUND VIBRATIONS INTO ELECTRICAL SIGNALS

Why is NIHL permanent?

BECAUSE IT DESTROYS HAIR CELLS IN THE COCHLEA, WHICH DON'T GROW BACK

Questions 25

Answers

1
Which part of the ear vibrates first?
OSSICLES
THE PINNA
EAR CANAL
TYMPANIC MEMBRANE
2
How is the human ear like a microphone?
ALL OF THESE
THEY BOTH CONVERT SOUND INTO ELECTRICAL SIGNALS
THEY BOTH COLLECT SOUND
THEY BOTH HAVE A DIAPHRAGM THAT VIBRATES
3
What has the widest range of all the human senses?
HEARING
TASTE
SMELL
SIGHT
4
What makes hearing different from all other senses?
IT'S THE STRONGEST OF ALL SENSES
IT IS THE ONE THAT DEVELOPS FIRST
IT IS THE ONLY ONE THAT IS MECHANICAL, BASED ON PHYSICAL MOVEMENT
ALL OF THESE
5
What do the ossicles do?
KEEP THE COCHLEA IN PLACE SO IT CAN FUNCTION
PIVOT IN SUCH A WAY TO AMPLIFY SOUND VIBRATIONS GOING FROM AIR TO FLUID
HOLD THE PARTS OF THE EAR TOGETHER
ALL OF THESE
6
Decibels are a "relative measurement." What does this mean?
SOUND INTENSITY IS COMPARED TO ANOTHER SOUND TO GET AN ACCURATE MEASUREMENT
YOU'RE PROBABLY MORE QUIET THAN YOUR RELATIVE
YOU ARE AS LOUD AS YOUR RELATIVES
EVERYTHING IS RELATIVE
7
Sometimes, class discussions are 100,000 times as loud as the TOH. How many decibels is this?
50 dB
5 dB
500 dB
100 dB
8
What is the "decibel scale?"
TO MEASURE SOUND FREQUENCY
NONE OF THESE
TO MEASURE SOUND INTENSITY (AMPLITUDE)
BOTH OF THESE
9
How does PLAYING a musical instrument affect the brain?
GIVES THE BRAIN A FULL WORKOUT
ENGAGES ALL AREAS AT ONCE
ACTIVATES THE CORPUS CALLOSUM
ALL OF THESE
10
How do logarithms help develop the decibel scale?
THEY USE THE EXPONENTS OF HUGE NUMBERS RATHER THAN THE NUMBERS THEMSELVES
THEY TAKE THE HUGE RANGE OF SOUND LEVELS AND NARROW IT DOWN
ALL OF THESE
THEY MULTIPLY THE EXPONENTS BY TEN TO GET DECIBELS
11
Which part of the ear is shaped like a snail shell?
AUDITORY NERVE
COCHLEA
SEMI-CIRCULAR CANALS
OSSICLES
12
What is NIHL?
NOISE INTENSITY HARM LEVEL
NONE OF THESE
NOISE INDUCED HEARING LOSS
NEW INTENSE HEARING LESSONS
13
How does music help with Alzheimer's patients and those who have had brain damge?
USES MUSIC TO ACCESS LOST MEMORIES
CAN HELP WITH NEUROGENESIS
ALL OF THESE
USES MUSIC AND LYRICS TO HELP RESTORE SPEECH
14
Once sound is converted to an electrical signal, what carries it to the brain?
EUSTACHIAN TUBE
AUDITORY NERVE
TYMPANIC MEMBRANE
COCHLEA
15
What were Alexander Graham Bell's engineers working on when they invented the decibel scale?
RADIOS
WIFI
LOUDSPEAKERS AND MICROPHONES
THE INTERNET
16
Which of these is NOT a harmful effect of noise pollution?
CHILDREN GETTING POOR GRADES IN SCHOOL
HIGH BLOOD PRESSURE
ACNE
HEART DISEASE
17
The decibel scale compares every sound to the TOH. What is this?
THE QUIETEST SOUND YOU CAN HEAR
THRESHOLD OF HUMAN HEARING
ALL OF THESE
A SOUND OF ZERO DECIBELS
18
How does LISTENING to music affect the brain?
ACTIVATES MULTIPLE AREAS
ACTIVATES LEFT HEMISPHERE ONLY
ACTIVATES RIGHT HEMISPHERE ONLY
ACTIVATES FRONTAL LOBE ONLY
19
Why is it difficult for sound vibrations to travel from the outer and middle ear TO the INNER ear?
BECAUSE SOUND IS BLOCKED BY THE OSSICLES
BECAUSE THE COCHLEA IS MADE OF BONE
ALL OF THESE
BECAUSE SOUND MUST TRANSFER FROM AIR TO THE FLUID INSIDE THE COCHLEA
20
Which of the following is NOT one of the auditory ossicles?
Stapes
Malleus
Incus
Cochlea
21
What do the "hair cells" do inside the cochlea?
PROTECT OUR EARS FROM COLD TEMPERATURES
PROTECT OUR EARS FROM LOUD SOUNDS
KEEP OUR EARS CLEAN
CONVERT SOUND VIBRATIONS INTO ELECTRICAL SIGNALS
22
How do the different areas along the spiral of the cochlea respond to sound?
EACH AREA RESONATES WITH A DIFFERENT FREQUENCY
HIGH FREQUENCIES ARE PICKED UP NEAR THE ENTRANCE
ALL OF THESE
LOW FREQUENCIES ARE PICKED UP NEAR THE CENTER
23
What kind of math helped develop the decibel scale?
LOGARITHMS
EXPONENTIAL FUNCTIONS
QUADRATIC FUNCTIONS
TRIGONOMETRY
24
Music can help with NEUROGENSIS. What is this?
FASTER CONNECTIONS INSIDE THE BRAIN
NEW GROWTH OF BRAIN CELLS
ACTIVATION OF ALL AREAS OF THE BRAIN
MAKING MUSIC SKILLS STRONGER
25
Why is NIHL permanent?
IT CAUSES BRAIN DAMAGE
IT BREAKS THE SMALL BONES KNOWN AS THE OSSICLES
BECAUSE IT DESTROYS HAIR CELLS IN THE COCHLEA, WHICH DON'T GROW BACK
IT WILL RUPTURE YOUR EARDRUM, PERMANENTLY
