GRAND PIANO AND UPRIGHT PIANO DIFFERENCES IN SOUND AND RADIATION
Ingolf Bork · 2023
To pianists.preference for the grand piano over the upright piano ls evident.Quality differences are ascribed not only to the sound but also to the mechanical behaviour of the action.The comparison of all acoustical and vibrational relevant pans reveals a lot of tundlonal dltterenoes of the two piano models.Therefore various measurement were done to document the different properties.0.9. the sound field due to the dlfterent radiation position of the soundboards was Investigated using model analysis software The elm of these lnvestlgetlons ls to line the quality relevant parameters for the plane In general which may lead to Improvements by better understandlng the contribution of individual parts to sound quality.
