Frequency is related to

The unit of volume is 

 

The unit of frequency is

A louder sound has a higher 

Drag the terms to the right place

hertz

decibel

pitch

amplitude

De amplitude is de hoogte van de trilling en zegt iets over hoe hard het geluid is (geluidssterkte). Dit wordt gemeten in decibel. 

De trillingstijd is de tijd van één trilling, hoe groter de trillingstijd, hoe kleiner de frequentie. 

Frequentie geeft informatie over de toonhoogte (hoe groter, hoe hoger) en wordt gemeten in Hertz. 

The higher the frequency, the                    the pitch

The higher the frequency, the                    the wavelength

Fill in the right term

higher

lower

longer

shorter

1. cochlea
2. nerves
3. inner ear
4. middle ear

Which part of the ear funnels sound waves?

1. Cilia
2. Ear Canal
3. Cochlea

What is wrong with the sound effects in Star Wars?

1. The noises are not loud enough
2. There is no medium in space
3. The speed of sound through space is too large
4. The frequency of the effects is to high

Which part of the ear transforms the sound wave into impulses that are send to the brain?

1. Hammer
2. Hair cells
3. Anvil
4. Ear drum

Which part of the ear is helping you to keep your balance?

1. Ossicles
2. Eustachian tube
3. Semicircular canals
4. Ear drum

You hear a sound. In what order will the sound wave travel through your the different parts of your ear?

auditory/ear canal

auricle

eardrum

ossicles

cochlea

Put in the right order

sound is picked up by the auricle

air in the auditory canal vibrates

the eardrum vibrates

ossicles vibrate

vibrations are past on to the cochlea

fluid in the cochlea vibrates

sensory cells are being stimulated

impulses are made

the auditory nerve brings impulses to the brain
