The invention provides a front chamber structure of sound insulation and energy absorption and the manufacturing method, comprising a front baffle, a reinforcing plate and a plurality of sound insulation and thermal insulation materials between the front baffle and the reinforcing plate. The invention is characterized in that the front baffle and the reinforcing plate are welded into a whole through spot welding; the outer layer of the front baffle is coated with the sound insulation and thermal insulation materials, and the outer flank of the reinforcing plate is covered with anti-damping materials, such as asphalt panel and other materials. The invention has an advantage that the noise in the cab of an automobile can be reduced by effectively insulating and absorbing the high and low frequency noises caused by the automobile engine and other parts.
