The influence of nicks on the sound properties and the airflow in front of flue organ pipe

Popis výsledku v původním jazyce

Nicking is a well-known voicing technique of metal flue organ pipes widely used by Czech organ builders in history. Its effect is investigated in this paper. The sound analysis results and the PIV images of the airflow in front of the mouth were studiedto achieve more advanced state of the art in organ pipe diagnostics. Both measurements were performed in steady state part of pipe sound. The results of the sound analyses are in accordance with organ builders experience ? the depression of higher harmonics was observed in the frequency spectrum after pipe nicking. Airflow analysis shows significant differences in vector velocity maps ? decrease of vector lengths near the flue. The article is a part of Proceedings of the Third Vienna Talk on Music Acoustics, held on 16?19 Sept. 2015, University of Music and Performing Arts Vienna.
