Expiation (Kaffara) for hearing music?

This question is for those who believe Music is forbiden (Haram). If someone hear music, is there any Kaffara (Expiation or atonement) mentioned in Islam to erase the sin ? The reason I am asking is we can control what we can see but like that we cannot control what we can hear. For example, when we travel we hear many things and music can be one of this. We cannot shut our ears like we can close our eyes. Jazzak Allahu Khaira
