Sound
- Waves
- Particle Waves
- Particles are forced together
or pushed apart
- This is a longitudinal wave
- This is a longitudinal wave
- Particles are forced together
or pushed apart
- Sound can be translated into
transverse waves using an
oscilloscope
- The larger the amplitude, the louder the volume
- The larger the wavelength, the lower the pitch
- Hertz (Hz) is a frequency measure. It is the
amount of waves in a second
- Therefore it can tell us the pitch - the larger
the Hz, the higher the pitch
- Therefore it can tell us the pitch - the larger
the Hz, the higher the pitch
- The larger the amplitude, the louder the volume
- Particle Waves
- The Ear
- The ear has three sections:
- Outer Ear
- The inner ear collects sound which
vibrates the eardrum
- Sound is collected by the
Pinna (cartilage)
- This magnifies 3x-4x
- Sound is collected by the
Pinna (cartilage)
- The inner ear collects sound which
vibrates the eardrum
- Middle ear
- Sound travels along three bones
- This amplifies the sound 22x
- This amplifies the sound 22x
- It is filled with air
- It is joined to the back
of the throat
- This is to relieve pressure
- Both sides of the eardrum must
have similar air pressure levels
- Both sides of the eardrum must
have similar air pressure levels
- This is to relieve pressure
- Sound travels along three bones
- Inner ear
- This is made up of two main structures
- Cochlea
- This detects sound
- The ossicles create waves in the fluid
- Sensors detect the waves and send nerve impulses to the brain
- Sensors detect the waves and send nerve impulses to the brain
- The ossicles create waves in the fluid
- This detects sound
- 3 Semi-circular canals
- These are placed in each plane of movement
- X - Across
- Y - Up
- Z - Along
- X - Across
- These are placed in each plane of movement
- Cochlea
- Fluid filled
- This is made up of two main structures
- Outer Ear
- The ear has three sections:
- Properties
- Sound is not part of the
electromagnetic spectrum
- It travels as a particle wave
- Therefore, it requires the
vibration of particles and objects
- Sound does not travel in space or a vacuum
- Sound does not travel in space or a vacuum
- Therefore, it requires the
vibration of particles and objects
- Sound is not part of the
electromagnetic spectrum
