Humans can only hear a certain range of sound frequencies. 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...

How our ears hear different frequencies, and how they work with the brain to turn these into sounds which we understand. Biology - Being Human - Learning Points. Sounds are simply movements of air molecules. Our ears are extremely...

Sounds can vary greatly: extremely quiet or deafeningly loud, high and shrill to low and booming. Why are they so different? Physics - Waves - Learning Points. Sound is a vibration passed to and fro along particles forming a wave. It can...

We use a sounding board called a sonometer to investigate how the pitch of sound changes when the length of wire being plucked changes. We change the position of a moveable bridge to change the length of the wire and discover that...
