The development and presentation of noise control engineering and hearing conservation seminars, customized to the needs of the client are provided. In addition, at least twice per year we offer Council for Accreditation in Occupational Hearing Conservation (CAOHC) approved courses for Certification of Audiometric Technicians. The detail and complexity of our seminars are adjusted based on the background of the audience. Typical groups we often address are industrial hygienist, corporate design and plant engineers, safety personnel, nurses, audiologists, architects, attorneys, and in-plant personnel. Since 1985 we have presented a one-day Professional Development Course (PDC) on Noise Control Engineering, which has always be rated as one the top ten courses out of 100+ specialized PDCs offered at the American Industrial Hygiene Conference and Exposition. In addition, since 1990 we have conducted a 2.5 day noise control seminar every six months for 3M and Procter & Gamble Company engineers and health and safety professionals, and we often receive feedback from students that our course is the most professional, practical and useful seminar they have ever attended.
