Sound attenuation from earmuffs and earplugs in combination: maximum benefits vs. missed information.
INTRODUCTION Noise levels from military aircraft range from 100-130 dBA. Peak pressure levels from large caliber weapons may reach 180 dB SPL. To protect against hearing loss, individuals are encouraged to wear double hearing protection. This study determined ways to maximize benefit. METHOD Hearing thresholds from 0.25-8 kHz and consonant discrimination were assessed in normal-hearing subjec...
متن کاملAttenuation of earplugs worn in combination with earmuffs.
If the attenuation that can be provided by a single hearing protection device (HPD) is inadequate for a given noise exposure and if noise control procedures are impracticable, the only remaining alternative is to use dual protectors, i.e. an earplug plus an earmuff. Such a combination can provide additional protection but it has long been recognized that the resultant noise reduction falls shor...
متن کاملPractice-based Improvements in Healthcare
A central problem for the healthcare sector today is how to manage change and improvements. In recent decades the county councils in Sweden have started various improvement initiatives and programs in order to improve their healthcare services. The improvement program of the Kalmar county council, which constitutes the empirical context for this thesis, is one of those initiatives. The purpose ...
متن کاملNoise attenuation and proper insertion of earplugs into ear canals.
OBJECTIVES The study was done to determine whether the noise attenuation attained with the use of earplugs can be improved by teaching the proper insertion of earplugs to users. METHODS Fifty-four randomly selected male subjects were divided into an untrained group (25 persons) and a trained group (29 persons). The trained group was given a lecture on earplug insertion and allowed to practise...
متن کاملSleep-related improvements in motor learning following mental practice.
A wide range of experimental studies have provided evidence that a night of sleep may enhance motor performance following physical practice (PP), but little is known, however, about its effect after motor imagery (MI). Using an explicitly learned pointing task paradigm, thirty participants were assigned to one of three groups that differed in the training method (PP, MI, and control groups). Th...
