Influence of Playing on the Tonal Characteristics of a Concert Piano - Dataset

Dataset supporting conference proceedings publication: <strong>## Abstract</strong> Well-maintained pianos are said to ”mature” and to ”change for the better” over the first years. When auditioning concert<br> pianos for purchase, technicians do often not choose the best sounding instrument but the one with the greatest potential<br> for future development. The present work addresses the following questions: Are structural changes measurable on a<br> piano after one year of operation in a concert house? Are these changes perceivable by listeners?<br> Measurements are performed on two occasions: First, on a brand new instrument prepared for sale. Second, on the same<br> piano after having been played for one year in a concert hall. Single notes are recorded with dummy-head-microphones<br> in player position in an anechoic chamber. An extended ABX listening test engaging approx. 100 players, tuners,<br> and builders, addresses the questions whether a variation in tonal quality is audible and if so, what sound properties<br> could lead to a perceived difference. Semantic sub-grouping allows for indication on the vocabulary listeners of varying<br> expertise use to verbalize their sensation. The statements give hints on what could have changed over the year and<br> are used as a basis for the analysis of corresponding physical properties and psychoacoustic parameters related to the<br> described sensations. <strong>## Data Structure</strong> <strong>### Naming Rules:</strong> <strong>Example:</strong> 'D1_PROD07_01__0000_M0000.csv' Ignore the <em>D1</em> <em>PROD07 </em>is before the year in a concert hall, <em>PROD08 </em>is after the year. <em>01</em> is the key (range: <em>01-88</em>) Ignore the <em>0000.</em> <em>M0000 </em>is the take (range: <em>M0000-M0004</em>) .csv files contain the data, the corresponding .txt files are the headers. <strong>### Columns in .csv file:</strong> <strong>Time [s]</strong>; Time vector <strong>Kistler 9722A500 [N]</strong>; Force sensor, measures the key / key bed impact force <strong>PCB 352C23 [m/s^2]</strong>; Acceleration sensor, measures the acceleration at the bridge (at the hitch pins of the corresponding string) in direction normal to the soundboard. <strong>HSU 3.2 left [Pa]</strong>; Left ear channel of dummy head, measures sound pressure in player position. <strong>HSU 3.2 right [Pa]</strong>; Right ear channel of dummy head, measures sound pressure in player position. sample rate = 50000 The listening test utilizing this dataset is still online (however, your input will not be evaluated): http://www.culturalheritage.digital/listeningtest/ Feel free to contact me for comments or questions: [e-mail]
