Can my baby's hearing be damaged?

There is well-recognised damage to the hearing of the foetus/unborn baby as a result of various 'intrauterine infections' - particularly the Rubella/German Measles virus. It is also true that a response to external sounds can sometimes be demonstrated. However, there is considerable protection afforded to your baby's hearing by the presence of the fluid of the amniotic sac as well as the tissues of your uterine wall, abdominal muscles and skin, etc.

'Response' is one thing, but 'damage' is another - the chances of harm occurring to the eardrums of your baby from even a very loud external source is most unlikely. I am sure that you have no real cause for concern.
