A revolution in custom hearing protection

The PACS Pro31 is a breakthrough in high-noise filtering, giving you an almost flat sound reduction.

The next generation of filter design

The PACS Pro filter series has been designed anew with the wearer in mind. For starters, it’s smaller than many competing filters, meaning that it can fit into smaller ears without any protrusion which is great for both comfort and aesthetics because it will always fit snugly underneath a helmet or other head wear. The filters are also removable, so you can clean and maintain your earmoulds and your filters – giving you the maximum life and the best value for money from your plugs. In addition, the PACS series are water-resistant, so they can be used outside or in high moisture environments and can withstand perspiration without it damaging the filter membrane.

The curse of the occlusion effect

Trying to create a natural sounding earplug is no mean feat as far as your own voice is concerned because, as you may have experienced, when you block off your ear canal your own voice starts to boom inside your head (this is what we call occlusion). This is caused by sound that is carried to your ear canal through the cartilage at the side of your head, which usually escapes through the open ear canal so is not heard. When we block off the canal, this sound cannot escape and so creates that booming effect. A large amount of occlusion can be eliminated by ensuring that the earplug sits deep enough into the ear canal to extend past the cartilage. This ensures that the sound hits the plug and is deadened rather than entering the canal at all. The PACS Pro filters go one step further by being vented to allow sound to pass both ways, meaning that remaining sound can escape directly through the filter, providing one of the most natural sounding earplugs available.

Tailer made for you

The PACS Pro31 earplug is custom-made using soft medical-grade silicone, so you get the very best in isolation and fit, allowing you to wear them for hours at a time without fatigue or discomfort. Each custom earpiece is manufactured to the highest standards, ensuring you get a comfortable, discreet and effective hearing protector that can be fitted quickly, easily and securely every time.

PACS Pro31 custom earplugs and filters have been tested and certified to AS/NZS-1270 standards as a Class 5 Hearing Protector as well as the The European Standard for ear plug hearing protectors.

    I work FIFO and on various sites. A lot of the time we spend all day having to wear mandatory hearing protection for the areas we are in, and sometimes double hearing protection of earplugs and earmuffs. My new PACS Pro31 offers me a high level of hearing protection with comfort. Only certain earplugs work for me, so am very happy that I have something that now fits like a glove and won’t give me earache after extended periods of wear. Highly recommend spending the money on comfortable and quality products. Thank you, Andrew H.

    Both sets of earplugs are perfect and I will be highly recommending your products to my friends and co-workers. The case, the fit, and the noise filtering are superb and fit for each of their tasks; I could not hope for better. Nick C.
