HPD Fit testing

Service Description

The fit testing of HPD is recommended within AS 1269.3 workers because the method of measuring attenuation of HPD in the laboratory (AS 1270) could differ significantly from real-world fitting and attenuation. AS 1269.3 recommends: - that individuals are trained in the selection and use of HPD; - what needs to be provided in the training; - that evaluation of HPD is undertaken; - individuals should be trained and fitted by an appropriately trained person with substantial knowledge of hearing protection. RED OHMS Group can provide training in HPD selection and use, then provide evaluation of fit with an objective fit testing method, the 3M E-A-Rfit™ Dual -Ear Validation System. This equipment: - tests both ears simultaneously in less than 5 seconds; - has earmuff and earplug - testing capability; - tests at 7 standard frequencies – 125Hz to 8000Hz.
