Created page with "==Key Stage 4== ===Meaning=== Infrasound is sound below a frequency of 20Hz. ===About Infrasound=== : Infrasound is any sound which is too low pitched..."

New page

==Key Stage 4==
===Meaning===
[[Infrasound]] is [[sound]] below a [[frequency]] of 20Hz.

===About Infrasound===
: [[Infrasound]] is any [[sound]] which is too low [[pitch]]ed to [[hear]]. Since the lowest [[frequency]] a [[human]] can hear 20Hz, then [[infrasound]] is any [[sound]] below that.
: [[Human]]s cannot [[hear]] [[frequency|frequencies]] below 20Hz because their [[Ear Drum|ear drums]] are too small.
: Large [[animal]]s such as [[whale]]s and [[elephant]]s can [[hear]] [[infrasound]] because their [[Ear Drum|ear drum]]s are larger than [[human]] [[Ear Drum|ear drum]]s.
