Full of car sound

I found that we live in full of car sound. New York is mostly windy and we always walk with or against the wind. We cannot see the wind, but always feel and hear. In the city, sound of wind blends with car sound. I have not recognized that much, and I thought those sound I heard from video was wind sound when I first saw a movie. However, I realized “Oh! it is mostly car sound.” Even in the park when we tried to capture birds’ movement, I cannot hear their sounds but car sound. I tried to hear bicycle’s sound, dogs’ sound, and others’. All sounds are mixed but I only recognize car sound. Maybe car sound is too prominent and our nature’s sound is too weak to hear? Anyway, I was so happy when I heard quite vivid birds’ sound on the street.
