List of sounds

A crash is a loud noise, usually made when something hits something else. You might drop saucepans to the floor with a crash. Cars can crash into things. The photo is of a wave crashing into the shore.

A crunch is a crackling noise that some things make as you break it. If you step on loose snow it will crunch under your feet. Many breakfast cereals make a crunch noise as you eat them.

An echo is reflected sound. You get echos most often in enclosed spaces with hard walls, like an empty room with wooden floors, or the inside of a large concrete pipe like in the picture. If you make a noise in a place like this, the noise you make sounds like it is being repeated back at you again and again, getting quieter each time.

A groan is a low sound you make when you are sad or in pain.

A hiss is a sharp noise made by animals like cats, snakes and geese when they are angry. Air escaping at high speed from a small hole can also make a hissing noise, for example when you fill your tyres with air, you often hear hissing sounds.
