| Abstract: | A technique is described which enables the major reflections produced by a pulse in an open plan space to be identified, isolated and their frequency spectra determined. No existing pulse source was found to be completely suitable for this purpose and the paper reports the development of a new source which gives a short, clean pulse from a blank cartridge by providing a free combustion zone. An application of the technique to the measurement of the oblique incidence absorption properties of a ceiling is described. |
