Re: Random punter question of the night
Great post Ivan.
Generally speaking, the noise in the womb is going to be very muted, as the transitions from different mediums is going to have impedance changes, and mute the signal.
The amniotic fluid is going to provide much more protection than just fingers in the ears. The x factor is going to be the sub frequencies. I am not of the opinion that since the sub frequencies are diminished on the Fletcher Munson curves that they are not to be worried about.
Also the OP states "pregnant woman", but it seems agreed that the concern is with the unborn child. (I am of the opinion that pregnant women should be active, interactive, and robustly involved in life, unless it is a bed rest situation.)
But my biggest concern is of once the baby is born. From what I have learned it is very hard on young children's hearing to be exposed to loud sounds before their ears, and muscles that protect the ears are formed. I don't see too many babies/toddlers at concerts, but I get pissed when I see babies at sporting events just so they can be flaunted on the jumbo trons. The crowd noise levels at these events can go well beyond what is safe for those young ears. Get a baby sitter, and leave them in the relative quietness of the home, where they belong.
