The Collection of historical instruments of Acoustics of the University of Palermo

In the Historical Collection of Physics Instruments of the University of Palermo, on exhibit at the Department of Physics and Chemistry, in the historic building of via Archirafi 36, about twenty instruments of acoustics are preserved. Most of these instruments have been made in the second half of the nineteenth century in Paris by the maker Rudolph Koenig and bought by the physicist Pietro Blaserna during his stay in Palermo as professor of Experimental Physics. This article shortly describes the Historical Collection of Physics Instruments and particularly three instruments of Acoustics.
