AN EVALUATION FOR USE IN AUDIOMETRY OF THE NOISE ATTENTUATION OF THREE TYPES OF CIRCUMAURAL EARMUFFS.
Abstract
In a study designed to find the best circumaural muff for routine testing of hearing, especially in group testing situations, three good quality circumaural muffs, commercially available, were compared. The 'Otocup' was found superior in noise-attenuation properties. Data is presented which should be useful as a base for equipment specifications for audiometric clinics. (Author)
