From past to present, performance spaces are being designed in order to provide better listening conditions according to their function. Rooms for classical music have different qualities in comparison to rooms for speech, for instance. However, while acoustic design regarding western-originated performances have been present for centuries, no such attempt has been made for Turkish classical music (TCM). This study aims to search for possible acoustic conditions that would complement the characteristics of TCM and try to improve the overall quality of spaces where TCM may be performed. After an in depth analysis of room acoustics parameters, acoustic evaluation systems and characteristics of TCM, spectral analyses are done for western classical music, opera and TCM, in order to understand the distinctions between the three. Afterwards, three different performance spaces with different qualities are modelled digitally in the 3D environment which were then transferred into Odeon room acoustics software, where anechoic audio recordings of TCM are auralised. A listening test is made with the auralisations for the correlation of objective and subjective acoustic parameters, and an acoustic evaluation survey is conducted to the listeners. Afterwards, a virtual room is modelled with conditions close to an anechoic room, where various changes are made in order to achieve better conditions for TCM through trial and error. Finally, four alternatives with the best conditions are taken into a listening test. The results are believed to yield close-to-optimum acoustic conditions for TCM, and may be used for in depth future studies.

Efficient Synthesis of Room Acoustics via Scattering Delay Networks De Sena, Enzo; Hacıhabiboğlu, Hüseyin; Cvetkovic, Zoran; Smith, Julius O. (2015-09-01) An acoustic reverberator consisting of a network of delay lines connected via scattering junctions is proposed. All parameters of the reverberator are derived from physical properties of the enclosure it simulates. It allows for simulation of unequal and frequency-dependent wall absorption, as well as directional sources and microphones. The reverberator renders the first-order reflections exactly, while making progressively coarser approximations of higher-order reflections. The rate of energy decay is clo...
A study on improving decisions in closed set speaker identification Demirekler, Mübeccel; Saranlı, Afşar (1997-04-24) In this study, closed-set, text-independent speaker identification is considered and the problem of improving the reliability of the decisions made by available algorithms is addressed. The work presented here is based on the idea of combining the evidences from different algorithms or decision strategies to improve the recognition performance and the reliability. For this purpose, the models generated by a single algorithm for 17 speakers from the SPIDRE; database are considered and a matrix of speaker-to-...
Comparison of PWM and PFM induction drives ID in,egarding audible noise and vibration for household applications Ertan, Hulusi Bülent (2004-11-01) This paper is aimed at comparing the performance of pulse frequency modulation (PFM) and pulsewidth modulation (PWM) techniques regarding audible noise generated from inverter-driven induction motors. For the purpose of illustrating the performance of the two modulation techniques, a drive developed for washing machine applications is considered. First, the measured and simulated harmonic content of this inverter is compared with the measured harmonic spectrum of a three-phase input-output commercial variab...
Investigating the correlation between magnetic Barkhausen noise emission and the fatigue life of shot-peened AISI 4140 steel Çalışkan, S.; Gür, Cemil Hakan (British Institute of Non-Destructive Testing (BINDT), 2019-01-01) The performance of engineering components under conditions of fatigue can be improved by shot peening. The location and magnitude of the highest residual compressive stress, the depth of the compression zone and the stability of the residual stress state during cyclic loading are critical parameters for maximum utilisation of the advantageous influence of shot peening on fatigue performance. For accurate assessment of fatigue lifetime, residual stresses should be considered because they are algebraically su...
A new method of curve fiting for calculation of reverberation time from impulse responses with insufficient length Özgenel, Çağlar Firat; Sorguç, Arzu (2012-12-01) Most of the room acoustics evaluation parameters are calculated from the energy decay curve obtained from the room impulse response. Schroeder's backwards integration method is one of the most commonly used methods to obtain room impulse response. Although, the method holds its validity since 1964 and used extensively, obtaining room impulse response with sufficient length to observe total energy decay requires high computational cost especially in highly reverberant rooms. In such cases, present acoustical...
