A while ago I changed the bulldozer sounds because I decide to demolish and rebuild an entire city from scratch. And I had to put the speakers on mute, cause the TF sound for bulldozing is extremely annoying. I changed those to birds signing.
After the last update I decided to verify files integrity and I lost those sounds. Once I started playing the game again, I was so angry at the sounds. Its really unbearable. So I decided to make a mod to change them.
There are no birds sounds, but nice and soft construction site short sounds that won’t make you angry
Here is my first mod: http://www.cimexchange.com/files/file/888-better-bulldoze-sounds/
