As multichannel sound systems become more and more widespread, the issues to how to obtain optimal sound reproduction become more apparent. Although the matter of level calibration is rather trivial for stereo sound systems, it has been found that it does critically affect perceived sound quality. The more complex and often sub-optimal multichannel set-up introduces a whole new range of problem...

The purpose of the research is to analyze features sound recording in open space from a technological point view. To do this, following tasks should be performed: establish role when it performs function dominant environment during speech or recording; prove importance obtaining intelligible microphone an space, taking into account influence extraneous sounds. Research methodology. methods have...

Recent technological trends facilitate threedimensional stereophony. To this day, no internationally agreed standard for three-dimensional sound reproduction exists. Fundamental research is needed to define basic system parameters and ensure compatibility between different formats. Background in spatial audio perception, stereophonic audio reproduction, and automatic channel format conversion i...

Introduction: Recent studies have acknowledged the potential of convolutional neural networks (CNNs) in distinguishing healthy and morbid samples by using heart sound analyses. Unfortunately the performance of CNNs is highly dependent on the filtering procedure which is applied to signal in their convolutional layer. The present study aimed to address this problem by a...

Background: Noise pollution is the third most dangerous risk factor for human health after air and water pollution. The aim of this study was to evaluate the effect of noise pollution on sleep disturbance among Neyshabur governmental teaching hospital staff, Iran, in 2015. Materials and Methods: This cross-sectional study was conducted in winter 2015. The sample size was 261 people from 2 hosp...

  For any organization sound marketing strategy and quality assurance play vital role in the growth of the organization. The price, quality and service, service centers, friendly attitude, Discounts on sales, esthetics, store location and appearance, ease of operations, guarantees and warranties, adopting new ideas, and flexible payments terms were considered to study the perceptions of the res...

Music information indexing based on timbre helps users to get relevant musical data in large digital music databases. Timbre is a quality of sound that distinguishes one music instrument from another among a wide variety of instrument families and individual categories. The real use of timbre-based grouping of music is very nicely discussed in (Bregman, 1990). Typically, an uncompressed digital...

Problem Task: combining multiple types of features for music classification from raw audio signals • Whether-we need multiple features? • How-to combine different features? • What-is the best feature and combination scheme? Features Taxonomy of audio features • Timbre features capture the quality of the sound and has much to do with the instrumentation of the music. • Temporal features capture ...

Background & Aims of the Study: Among the environmental pollutions, noise pollution, due to the potential physiological and psychological effects on humans, is of a particular importance. Exposure to noise can result in hearing loss in citizens. Health risks from noise associated with road traffic. Noise health effects are the health consequences of elevated sound levels. This ...
