Propagation and dispersion of acoustic waves is one of the important phenomena in physics. Acoustic-waves are nowadays widely used in a variety of applications ranging from underwater communications, identification and specification of the internal defects of materials to extracorporeal shock wave lithotripsy. Apart from application and utilization of such phenomena, study on production and pro...
Sound measured at various points around the environment can be evaluated by a series of multi-pole sources and their acoustic strength can be acquired. In this numerical study, a method, called the inverse method, was examined to achieve this goal. A variety of arrangements of different sources were considered and the acoustic strength of these sources was acquired. Through the application of t...
in this study, the disadvantages of wood, which is widely employed in producing music instruments, are discussed. for example, high moisture sensitivity, low impact resistance, and time-consuming procedure as well as various properties of different species or in several parts of one specimen which are the main problems of wooden music instruments are extensively discussed in this paper. many ma...
This paper provides a novel training data selection method to construct acoustic models for automatic speech recognition (ASR). Various training data sets have been developed for acoustic modeling. Each training set was created for a specific ASR application such that acoustic characteristics in the set, e.g. speakers, noise and recording devices, match those in the application. A mixture of su...
background: repeated efforts by researchers to impose voice changes by laryngeal surface electrical stimulation (ses) have come to no avail. this present pre-experimental study employed a novel method for ses application so as to evoke the motor potential of the internal superior laryngeal nerve (isln) and create voice changes. methods: thirty-two normal individuals (22 females and 10 males) pa...
