PRO-20 Custom Protectors

The PRO-20 filter provides attenuation specifically designed for high noise situations where there is an emphasis on higher pitch frequencies. For motor sport the PRO-20 provides protection against wind, road and engine noise whilst allowing the wearer to maintain situation awareness, hear the note of the engine and communicate clearly when stationary.

Designed from the ground up for motorsport and industry the PRO-20 is the ideal filter for demanding environments. The PRO filter also provides water resistance so it will carry on performing in the hot or humid conditions of a crash helmet or demanding industrial environments with no detriment to the attenuation.

The edge you want with the protection you need

The PRO-20 offers protection that’s been specifically designed for those exposed to dangerous high frequency noise. Its dB reduction increases gently up to the high frequencies so you can hear everything you need to and not what you don’t. Keeping the attenuation less agressive in the lower frequencies gives you greater situation awareness and allows you to communicate comfortably without the need to keep removing and replacing your plugs so you can put your hearing protection in and leave it there all day if necessary. With an average attenuation of 20dB the PRO-20 can increase your safe exposure times by up to 6.5 times so you can enjoy your hobby or occupation with confidence and, with its slimmer and more discreet profile, in complete comfort.

The next generation of filter design

The PRO filter series has been designed anew with the wearer in mind. For starters, it’s smaller than many competing filters which means 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. The filters are also user-swappable so you can chop and change as your environment demands to any other filter in the PRO range giving you complete control over your protection with just a single set of earmoulds. In addition, the HF 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 will have experienced, when you block off your ear canal your own voice starts to boom inside your head, this is what we call occlusion. Occlusion is caused by sound that is carried to your ear canal through the cartilage at the side of your head and 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 so that the sound hits the plug and is deadened rather than entering the canal at all but the PRO filters go one step further. The PRO series are vented to allow sound to pass both ways which means that remaining sound can escape directly through the filter providing one of the most natural sounding earplugs available.

Tailor made for you

The PRO-20 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 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.

Produced in clear as standard, this range can be produced in black, yellow, white, red, blue and swirl combos (i.e. red/yellow, black/yellow, black/white) and can be supplied with neck cords if required. Please note these neck cords are a device to retain the moulds and should NOT be tugged on to aid removal, as this can damage the moulds. Supplied with carry case, wax cleaning pick and otoferm crème.

Where can I buy ACS products?

ACS products are available from a nationwide network of Audiologists as well as directly from us at our offices in Banbury. You'll need to make an appointment to have impressions taken which will then be sent on to us to allow us to manufacture your custom-fit products. To find your nearest Audiologist see the complete list on our Find A Dealer page. Please note that production time is always dependent upon orders received.  The skills and experience involved in making our hand-crafted products are not acquired overnight so employing more staff, whilst increasing our labour force, does not bring an immediate reduction in production time - please bear with us in times of increased demand for our products
