Sound at the Extremes
Why do men have lower voices than women? What is the worst sound in the world? Can a whale kill a fish using only a bubble?
Join us as we journey from one extreme to the other, from high sounds to low sounds, loud to quiet, nice to nasty!
Test yourself! Are you the loudest audience member, the highest, or maybe you have the sexiest voice?
Using interactive demonstrations and live sound experiments we investigate all the amazing properties of sound and what we might be using it for in the future.

Learning Objectives
Key stage 3
After watching the show Key Stage 3 pupils should:
- Understand that vibrations cause sounds and that sound travels as a wave
- Understand that the frequency of the wave determines the sound's pitch, and the amplitude its volume.
- Recognise that animals, including humans, use sounds of different pitches to communicate, in mating rituals and as effective predators.
Key stage 4
After watching the show Key Stage 4 pupils should:
- Know what ultrasound and infrasound are and describe some of their effects.
- Describe how a sonic boom is produced
AS and A level
After watching the show AS and A level pupils should:
- Understand that resonance gives more energy to vibrations
- Understand that a note is generated when the matter vibrating is of a fixed length and the note or notes produced have a frequency related to this length.
