User tests of ear defenders.
Ten different common muff-type ear defenders were tested by 50 potential users for comfort and ease of use. Results showed short-term (3 min) impressions to be a good predictor of long-term comfort; defenders were ranked for comfort and pointers are given for important design features. Only comfortable ear defenders will be worn properly.
