thank u so much

The baby in the womb is surrounded by amniotic fluid and also the uterine muscle walls will muffle any sounds. So what you hear as a very loud sound the baby will get a low muffled version. Relax.

nite time dog barking sound like that

it is purly mind-set. keep calm and try to divert your attention on something else which comforts you and you should be good

Try to be calm. what kind of sounds ?
