Clearsound from ACS Hearing Protection is a custom moulded hearing protection system that uses a new range of patented RC acoustic filters for people working in noise levels below 100dB(A). Clearsound offers better transparency for the higher frequency content and brings it into balance with the lower frequency content of the sound. The improved attenuation characteristic produces two important properties.

Firstly, a lower range of overall attenuation levels prevents the risk of overprotection. Secondly, less distortion of the original sound character improves speech intelligibility and work sound/warning signal perception.

Biopact are tailored to the individual from exact impressions taken of the users ears allowing the production of comfortable, natural fitting earplugs that can be worn for long periods of time. The special attenuating filters are then fitted into the soft, durable, silicone earpieces.

Biopact is independently tested to ISO4689 and DIN17460. They conform to European Normalisation EN352-2 standards laid down for hearing protection and carry the CE 121 marking.
