Description

A REVOLUTION IN CUSTOM HEARING PROTECTION

The PRO 15 by ACS provides more subtle attenuation which is perfect for use in acoustic or orchestral environments, sloping up in the higher frequencies for protection against heavily played wind instruments. The vented design offers reduced occlusion, making communication and vocal performances sound more natural – resulting in a plug that is more transparent to the wearer. The complete plug (custom made in soft silicone) offers one of the most comfortable hearing protection solutions for unplugged musicians with the additional benefit of water resistance for increased longevity. The PRO-15 represents the next generation of musicians hearing protection.

PROTECTION JUST WHERE YOU NEED IT

The PRO 15’s attenuation curve is the result of a very specific design that satisfies two very important requirements. Firstly, the requirement of acoustic musicians to be able to hear what they’re doing whilst being protected from peaks in higher frequencies but where the overall noise is lower than for many other musicians. The PRO 15 solves this with a flat 12dB protection up to the midrange and then a gentle curve up to 15dB at the high end where many of the dangerous blasts from wind instruments sit. Second is the requirement for a hearing protector that conforms to the European Standard for hearing protection for use under the Noise at Work regulations. The EN352-2 standard specifies minimum protection values at specific frequencies and creating a low noise hearing protector can be difficult without dipping below these values. The PRO 15 provides protection that’s not only perfectly suited to the acoustic musician but also meets the requirments of EN352-2 so the musician and politician are perfectly happy.

THE NEXT GENERATION OF FILTER DESIGN

The PRO filter series has been designed anew with the wearer in mind. The filter is smaller than many competing filters, meaning 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 earmoulds. In addition to this, 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. 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 is 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. This means that remaining sound can escape directly through the filter providing one of the most natural sounding earplugs available.
