Several people, several minds
I found it interesting that everyone feels defferently about the sound even if it is the same sound.
For example, I do not mind if music is going or television is on and I can hear the sound while I am studying. I can still concentrate studying most of the time. I do not mind if someone takes shower and I can hear the sound of water running while I am sleeping in the middle of the night or early in the morning. I can still sleep confortably. I do not care at all. I dont consider those sounds as noise. But some people do hate hearing those sounds while they are studying or sleeping. Although I dont care about those sounds, I do care sound of people chatting alot and traffic noise.
I started recognising these thing, how people feel about the same sound, since i came here living with many people coming from different countries and culture background. And now i think there is tendency that people consider as noise depends on the culture and where you are form. What i found is, no evidence though, that Western people more likely to hate the sound of the water in the night time or early morning but Asian are not likely to. I will keep on researching on this topic and tell you the findings.
