Attenuation 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 کاملProtective effect of respiratory devices in farmers with occupational asthma.
To the authors' knowledge there have been no previous reports on the protection afforded by powered filtering respirators in farmers with occupational asthma attributed to the inhalation of organic dust. In order to investigate this question, 26 farmers with occupational asthma were challenged with an exposure to work-related dusts for up to 60 min. This resulted in highly significant increases...
متن کاملEfficiency of filtering materials used in respiratory protective devices against nanoparticles.
The basic aim of this research was to establish the efficiency of filtering materials widely used in respiratory protection devices with particular interest in their porosity, degree of electric and changeable process parameters, such as the flow rate of the test nanoaerosol and the size range of nanoparticles. Tests were carried out with an NaCl solid aerosol of 3.2 × 105 particles/cm3 for the...
متن کاملMeasurement of the attenuation characteristics of nonlinear hearing protective devices using the auditory brain stem response.
The purpose of this study was to determine the feasibility of using the auditory brain stem response (ABR) as a method of measuring the attenuation characteristics of nonlinear hearing protective devices. Sound field ABRs were recorded from seven normal hearing subjects with and without hearing protection. Three hearing protectors (two nonlinear and one linear) were evaluated. Test stimuli, con...
