Qualification methods for assessment of annoyance of impulsive sounds
(2014) Kukulski, Bartłomiej; Wszołek, Tadeusz
This paper presents the work on the problem of the qualification of impulsive sounds for applying the adequate value of impulsive adjustment. Impulsive events must be included in the assessment of noise in Poland. There is no agreement for using the objective methods that could qualify impulsive sounds on the basis of the measurable physical characteristics of the impulses. Moreover, the arbitrary classification includes only a few specified sources. The paper presents a review of the methods and criteria for the qualification of the impulses and provides the results of applying these methods on a certain impulsive noise source – the collision of train cars.
Guitar playing robot, a tool assisting instrumental research
(2014) Tokarczyk, Daniel; Pluta, Marek; Wiciak, Jerzy
This article is about the use of an automatic mechanism able to play an instrument in research about playing repeatability. Repeatability in this case refers to the time intervals between played notes in sequences. The subject will be discussed based on a guitar playing robot. During the research with the use of guitar playing robots, some conclusions were made that confirm that humans are unable to play sound sequences twice while maintaining high repeatability. It has also been proven that the use of a robotic musical instrument (RMI) helps obtain playing repeatability of sound sequences much more accurately than that obtained by a human musician
