Metallic noise is a type of sound that is produced when two metal objects come into contact with each other. The term 'metallic noise' can be broken down into three distinct words: CLANK, CLANG, and JANGLE. CLANK is a sharp, ringing sound that is made when two metal objects collide. CLANG is a loud, reverberating sound that is made when two metal objects are struck together. JANGLE is a rattling sound that is made when two metal objects are shaken together. All three of these words describe the sound of metallic noise.
