Physical Quantities

The results of the investigation of the room acoustic properties influence on the perception of the sound of percussion musical instruments are presented in the paper. At first, the acoustic properties of two rooms were determined without musical instrument. Subsequently, the acoustic properties of the rooms were determined during the presentation of cajon music. On the base of reverberation time (EDT, T30), Clarity C80, Definition D50 and bass index BI) we can conclude that the room of the Hron cinema is more suitable for musical presentation, but it cannot be considered as ideal one. The Royal Hall of Zvolen Castle has a smaller influence on the sound of a percussion instrument. The influence of room acoustic properties on the resulting sound of the instrument was evaluated only on the base of results obtained with using the objective methods by the physical quantities measurement. Finally, the design of these rooms modification is presented to achieve a better sound quality of percussion instruments.

Innovation and tradition are two fundamental factors in the design of new digital musical instruments. Although apparently mutually exclusive, novelty does not imply a total disconnection from what we have inherited from hundreds of years of traditional design, and the balance of these two factors often determines the overall quality of an instrument. Inspired by this rationale, in this article we introduce the Hyper Drumhead, a novel augmented virtual instrument whose design is deeply rooted in traditional musical paradigms, yet aimed at the exploration of unprecedented sounds and control. In the first part of the article we analyze the concepts of designing an augmented virtual instrument, explaining their connection with the practice of augmenting traditional instruments. Then we describe the design of the Hyper Drumhead in detail, focusing on its innovative physical modeling implementation. The finite-difference time-domain solver that we use runs on the parallel cores of a commercially available graphics card and permits the simulation of real-time 2-D wave propagation in massively sized domains. Thanks to the modularity of this implementation, musicians can create several 2-D virtual percussive instruments that support realistic playing techniques but whose affordances can be enhanced beyond most of the limits of traditional augmentation.

Acoustic Quality

Morus Alba or mulberry is a wood species that is broadly used in making musical instruments in Eastern countries. However, the mechanical and acoustical properties of this type of wood are not investigated properly. In this study a set of features, previously examined for other species, are applied to this wood and its acoustic quality is evaluated. Setar, a Persian musical instrument made of mulberry wood, is selected as the test case of this experiment. Different samples of wood are gathered and categorized based on their appropriateness for Setar construction. The quality of each sample is identified based on the Perceptual knowledge of professional Setar makers. The most effective features are then selected and their average values are calculated for high quality samples. The result of this study helps Setar makers to select proper raw material before making an instrument. In addition, this approach can be applied to other wood species used in music industry.

As a typical acoustics room, the sound quality of home theatre is an important standard to evaluate its design. Qualified acoustics design is the guarantee of good sound quality. The volume of home theatre is generally small, so the room size is similar to the low-frequency wavelength. Then the resonance will occur when the excitation of the sound source frequency acts on the natural resonance frequency of the room. At the same time, the secondary reflection of the room also interferes the direct sound emitted by the speaker, thus destroying the sound image. In order to solve the above problems, this paper took a home theatre as an example, analyzed the normal modes of the room by the theory of wave acoustics, and then made an acoustics design and simulation. The simulation results showed that the reverberation time was up to the relevant standards and the room acoustic quality environment was improved obviously after the acoustic design.

The Impact

This research investigated the potential of some European wood species for use in the manufacturing of the back plates of violins as an alternative to the quite rare curly maple wood. An experimental modal analysis was employed for this purpose using the impact hammer method. The modal analysis was performed both on the top and back plates, as individual structures, and then after being integrated into the violin body. The modal analysis envisaged the determination of the eigenfrequencies (natural frequencies), the number of spectral components, and the quality factor, as important indicators of the acoustic performances of a musical instrument. A multi-criteria analysis based on the values obtained for these indicators allowed interesting findings concerning the acoustic properties of the selected wood species (hornbeam, willow, ash, bird-eye maple, walnut, and poplar). Same as curly maple, they all have special aesthetics, but only hornbeam, willow, and ash wood proved to have acoustic potential as well.

Normal Speech

A large percentage of patients who have undergone laryngectomy to treat advanced laryngeal cancer rely on an electrolarynx (EL) to communicate verbally. Although serviceable, EL speech is plagued by shortcomings in both sound quality and intelligibility. This study sought to better quantify the relative contributions of previously identified acoustic abnormalities to the perception of degraded quality in EL speech. Ten normal listeners evaluated the sound quality of EL speech tokens that had been acoustically enhanced by (a) increased low-frequency energy, (b) EL-noise reduction, and (c) fundamental frequency variation to mimic normal pitch intonation in relation to nonenhanced EL speech, normal speech, and normal monotonous speech (fundamental frequency variation removed). In comparing all possible combinations of token pairs, listeners were asked to identify which one of each pair sounded most like normal natural speech, and then to rate on a visual analog scale how different the chosen token was from normal speech. The results indicate that although EL speech can be most improved by removing the EL noise and providing proper pitch information, the resulting quality is still well below that of normal natural speech or even that of monotonous natural speech. This suggests that, in addition to the widely acknowledged acoustic abnormalities examined in this investigation, there are other attributes that contribute significantly to the unnatural quality of EL speech. Such additional factors need to be clearly identified and remedied before EL speech can be made to more closely approximate the sound quality of normal natural speech.
