QuietEar Ear Plugs from HearTech offer variable noise reduction (VNR) patented technology, letting you hear what you need to hear (voices and other sounds in the voice frequency range) while protecting you from dangerous higher frequencies, and providing increased attenuation as the noise volume at the ear increases. QuietEar earplugs have a built-in acoustic filter in the form of a precisely designed vent. As the volume of noise increases at the ear, QuietEar automatically provides increased attenuation, resulting in higher noise protection at higher noise levels. This means at lower noise levels, you can easily hear voices without having to remove your earplugs. In addition, QuietEar offers differential noise attenuation at high and low frequencies, which means sounds in the range of the human voice are always attenuated less than the higher, more dangerous, frequencies. The vent also means QuietEar is more comfortable for extended wear, allowing your ears to breathe and reducing the "plugged-up" feeling common with many solid earplugs. Made of durable and washable pre-moulded silicone, QuietEar plugs last for months or even years as long as they are cleaned with mild soap and water after each use. The Heartech Quietear Earplug is truly innovative earplug. Reusable and washable there are 2 sizes to fit all ears; the Standard size will fit most people. A special container provided for storage. It is important to get the right size fit so the trial pack can be a wise buy for your first purchase of Heartech Earplug products.
