Description
Part 3 from a series of three films sponsored by the Leverhulme Trust and made by the Centre for Extension Studies at Loughborough University of Technology. 1976. for educational use only.
The film looks at several cases of machines with a high noise level where modification of design can, and has effectively, reduced noise. The principle of analysing, defining and isolating the source is illustrated. Cases shown include a fire engine cab, where noise levels were so high that the radio telephone could not be heard, and a saw where design modification has halved the original noise level. See under “Air Pollution” for three more films.
