Discover the sounds we can't hear and why they can be useful. Physics - Waves - Learning Points. The frequency of sound waves determines whether we can hear them. High-frequency waves, ultrasound, are used by animals and in medicine. Infrasound, low frequency waves, is used by homing pigeons to navigate. The range of sounds humans detects vary slightly from person to person. A Twig Context Film. Reinforce and extend the learning required by the curriculum. Twig’s context films show abstract concepts in action in the real world.\n
