Description: | The Natural Philosophy collection is based on the teaching and research at Aberdeen University in Natural Philosophy, expanded by items in subjects that have grown from Natural Philosophy to acquire their own identity. The area of acoustics is represented by a group of approximately forty items, mainly showing the principles of the subject, including the application to music. Three selected items in the collection: the 'Helmholtz Double Siren' has been described as "a siren in each of the cylindrical chambers was driven by a constant supply of air to produce notes of a fixed absolute pitch that could be measured using the central dials" (Reid, 2004). A trademarked Edison Standard Phonograph' designed by Edison demonstrates his great improvements of using a hard wax cylinder as a recording medium instead of the original tin foil. Our example is manufactured in New Jersey. A harmonium by Alexandre et fils, Paris, is part of the acoustic demonstration equipment used by Professor David Thomson, who wrote the article on Acoustics for the 9th edition of the Encyclopaedia Britannica. The Natural Philosophy collection's website provides background information to the collection and the key items.
Access to the collection is restricted and all enquiries should be sent to Dr J Reid, the Honorary Curator. Information compiled in consultation with the Honorary Curator.
