The prevalence of irregularity in rhythm and heart sound in apparently healthy small ruminants
This study was conducted on 384 clinically healthy sheep and goats from farms around Tehran suburb. The animals were divided into two equal groups (according to species) and then assigned into three age groups, two gender groups and female animals into two groups: late pregnant and non-pregnant. Heart sounds were auscultated by two cardiologists and heart rate and probable murmurs were recorded...
متن کاملClinical significance of cardiac murmurs: Get the sound and rhythm!
Murmurs arise when blood flow becomes turbulent, causing vibration of cardiovascular structures. Physiological murmurs or functional murmurs result from turbulent flow associated with normal blood flows at high velocity. Pathological murmurs are caused by a pathological condition such as valvular regurgitation or congenital cardiac disease. When a murmur is diagnosed, we first need to identify ...
متن کاملRhythm Facilitates the Detection of Repeating Sound Patterns
This study investigates the influence of temporal regularity on human listeners' ability to detect a repeating noise pattern embedded in statistically identical non-repeating noise. Human listeners were presented with white noise stimuli that either contained a frozen segment of noise that repeated in a temporally regular or irregular manner, or did not contain any repetition at all. Subjects w...
متن کاملMusical Rhythm , Linguistic Rhythm , and Human Evolution
THERE IS NOW A VIGOROUS debate over the evolutionary status of music. Some scholars argue that humans have been shaped by evolution to be musical, while others maintain that musical abilities have not been a target of natural selection but reflect an alternative use of more adaptive cognitive skills. One way to address this debate is to break music cognition into its underlying components and d...
متن کاملSound Re-synthesis from rhythm Pattern Features - audible insight into a Music Feature Extraction Process
For tasks like musical genre identification and similarity searches in audio databases, audio files have to be described by suitable feature sets. Since these feature sets usually try to capture diverse discriminative characteristics, it is interesting and desirable to create an acoustic representation of the feature set to support intuitive evaluation. In this paper, we present an approach for...
