Lady Cecily's Sound Box
A Victorian Music Hall Melodrama on Sound and Waves
When Lady Cecily Ruddle dies, her favourite granddaughter, Emily, inherits a box of curious gadgets. Might they be of interest to Thomas Edison or Marconi? They certainly are of interest to Emily's scheming twin sister, Elizabeth. The tale involves mistaken identities, murderous shenanigans and explores the principles of Sound technology with all the fun and gusto of the Victorian Music Hall!	Scientific Content	Back to Shows
	Key Stage 1 • The children are shown that sounds are created as the result of vibrations • Frequency is explained as the number of vibrations each second and is related to how we hear sounds (demonstrated with the use of a signal generator) • How sound travels through air is illustrated and its speed compared to that of light is shown with particular reference to thunder and lightning • The basic functions of the microphone and loudspeaker are explained Key Stage 2 • As KS1 but in greater detail... • Frequency is measured in Hertz and the range of human hearing • Amplitude is defined and its relation to the amount of energy carried by a wave is demonstrated • The carbon microphone and its use in the telephone is explained
