A platform for research: civil engineering, architecture and urbanism
A complete apparatus for absolute acoustical measurements
Requisites are: source of sound producing a simple tone of known intensity, instrument for measuring in absolute units a constantly maintained simple tone and series of experiments on propagation of sound from one to other in order to check theory of two instruments. Combinations embodying forms said to have been found suitable after research work are given.
