| THE ASSESSMENT OF THE ACHIEVEMENT OF THE SET OBJECTIVES WILL TAKE PLACE THROUGH AN ORAL INTERVIEW. TO PASS THE EXAM THE STUDENT MUST DEMONSTRATE THE BE ABLE TO KNOW THE VIBRATION AND NOISE MONITORING AND REMEDIATION TECHNIQUES ILLUSTRATED DURING THE COURSE. THEY MUST ALSO SHOW KNOWLEDGE OF THE THEORETICAL BASIS FOR THE STUDY OF MECHANICAL VIBRATIONS AND ACOUSTIC PROPAGATION. THE EVALUATION WILL BE EXPRESSED IN THIRTY. THE FINAL EVALUATION IS OBTAINED AS THE AVERAGE OF THE PARTIAL EVALUATIONS ON THE SINGLE ORAL QUESTIONS. THE MINIMUM EVALUATION LEVEL (18) IS ATTRIBUTED WHEN THE STUDENT HAS A FRAGMENTARY KNOWLEDGE OF THE THEORETICAL CONTENTS AND A MODEST ABILITY TO APPLY THE METHODOLOGIES ADDRESSED DURING THE LESSONS. THE MAXIMUM LEVEL (30) IS ATTRIBUTED WHEN THE STUDENT DEMONSTRATES A COMPLETE AND IN-DEPTH KNOWLEDGE OF THE METHODOLOGIES AND TOOLS AND HAS A CONSIDERABLE ABILITY TO USE THEM IN THE STUDY CONTEXT WITHIN THE CONTEXT OF A CORRECT THEORETICAL INTERPRETATION. HONOR IS GIVEN WHEN THE CANDIDATE DEMONSTRATES SIGNIFICANT MASTERY OF THE METHODOLOGIES AND TOOLS AND SHOWS CONSIDERABLE PROPERTY OF LANGUAGE AND INDEPENDENT PROCESSING CAPACITY EVEN IN CONTEXTS DIFFERENT FROM THOSE PROPOSED BY THE TEACHER. |
