The disappearance of sound in a pulse can be attributed to several factors, including attenuation, which is the reduction of sound intensity as it travels through a medium due to absorption and scattering. Additionally, the distance from the sound source plays a significant role; as sound waves propagate, they spread out, leading to a decrease in amplitude. Environmental factors like temperature, humidity, and obstacles can also affect sound propagation, further contributing to its diminished audibility.
The disappearance of sound is caused by blood flowing freely. The blood flows freely because there is no constricted artery.
There will be no systolic sound if blood is flowing freely. This occurs when there is no measurable constriction of an artery.
What causes the throbbing called a pulse?
Hydrocarbon eating bacteria

the pumping of the heart as it is irregular
The closure of mitral and tricuspid valves causes the first heart sound. The second heart sound is produced by the closure of semilunar valves (pulmonic and aortic valves).
a pulse iz cauzed cuz i said it iz caused

Yes, "pulse" is not an example of onomatopoeia. Onomatopoeia refers to words that imitate the sound they represent, such as "buzz" or "hiss." "Pulse" is a word describing a rhythmic beating or throbbing, not imitating a sound.
The potential causes of the sudden disappearance of bees in 2016 included pesticide use, habitat loss, and climate change. The consequences of this disappearance could have been a decline in crop pollination, leading to reduced food production and biodiversity loss.
Propagation time of any pulse is roughly the time needed for the leading edge of the pulse to travel from one point to another. It will be more accurate to say that the pulse is registered at a given point when its leading edge reaches half of the maximum value (amplitude) of the pulse. The propagation time of a sound pulse is equal to the distance between the measuring points divided to the sound velocity in the medium in which it propagates.
