Support tools for understanding and tackling noise trouble are developed. These tools help engineers who are not familiar with noise to learn noise reduction technique and process. The noise reduction technique consists of theoretical and experimental knowledge. Thus these tools use both knowledges to construct knowledge base. The experimental knowledges are extracted from variety of case studies about noise reducing works. Two types of tools were developed, noise guidance tool and noise expert tool. The noise guidance tool is made on card type data base and the noise expert system is on expert system construction tool which has inference process.
