A REVOLUTION IN CUSTOM HEARING PROTECTION
The ACS PRO20 acoustic filter has been designed to provide relatively flat attenuation to remove low frequency sounds but also progressive dampening at approximately 4kHz up to remove higher frequency sounds that can more readily damage your hearing. This to match the resonant frequency of the ear canal. It is specifically better for reducing higher pitch frequencies such as those found when playing an acoustic drumkit (e.g. cymbals, hi-hats & snare drums). The PRO20 provides an average of 20dB attenuation from 125Hz to 8kHz and is the ideal filter for demanding environments whilst still allowing the wearer to maintain situation awareness. All ACS PRO filters also provide water resistance so it will carry on performing in the hot or humid conditions of sweaty on-stage performances with no detriment to the attenuation.
THE EDGE YOU WANT WITH THE PROTECTION YOU NEED
The PRO20 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. Keeping the attenuation less aggressive in the lower frequencies gives you greater situation awareness. This 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 PRO20 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. 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 ear moulds. In addition, the PRO 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 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.
TAILOR MADE FOR YOU
The PRO20 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 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.
PRO20 earplugs and filters have been tested and certified to EN352-2: The European Standard for earplug hearing protectors.
