The sound of a baby laughing can creep me right out! :S Sorry. If it was my baby it might be different.
I agree with you, sandrajo, sirens panic me. I also hate to hear people arguing, especially in public.
Love the sound of my favourite songs, the sound of the sea when I walk the dog at the beach and it's empty but for us, the sound of my friends on the phone, especially if it's been an age since we caught up! Also the sound of people having a good time, be it laughing in the park, or screaming and giggling on a night out.
