Psychological responses Readings for Industrial Audiology Text: Supplemental: Attendance: The Noise Manual edited by EH Berger, LH Royster, JD Royster, DP Driscoll, and M Lane © 2000. Hearing Conservation in Industry by Alan Feldman & Charles Grimes, © 1985. Occupational Hearing Conservation by Maurice Miller & Carol Silverman, © 1984 Industrial Noise and Hearing Conservation by Julian Olishifski & Earl Harford, © 1975 Class attendance policy is consistent with University policy. In addition, four absences are allowed for whatever reason (approved or not, at your discretion). Beyond this the final grade is reduced by 1/4 of a letter grade for each additional absence. The final grade will be increased by 1/4 for each of the allowed absences that is not used. Perfect attendance improves performance by one full letter grade.
