Sort:  

the noise from the operation is very loud and might damage the ear if not properly prevented by using ear muffs. also the vibration of the device is said to affect blood circulation on the fingers. Operating the device periodically or using models that reduce vibration is one way to prevent that.

Alright. Except that the vibration cannot be reduced since it needs that motion to break the rock. It's nice though
