Description

This customized configuration is specifically designed for use in industrial settings. The ACS PRO 31 filters are highly effective in reducing noise levels ranging from 110 to 115 dB, thereby providing the user with a safe listening environment for up to 8 hours. 

In addition, the Grip-Style earmoulds have been designed so that the user can insert and remove earplugs without having to touch their ears with dirty fingers. The neck cord allows for temporarily removing and hanging the earplugs on the shoulder, and the bright, highly visible Neon Orange and Neon Yellow earplug colors provide quick, easy usage identification.

The PRO 31 is the latest filter from the ACS custom communication headset for non-combat aircrews in the British Air Force. It primarily has a very high attenuation effect to allow crew members to maintain external sound perception in noisy military aircraft. The PRO 31 filter reduces at least 30 dB below 1 kHz. It then starts to increase until it reaches a maximum attenuation of 40 dB at 8 kHz.

In the civilian application, the PRO 31 is suitable for heavy industries such as metal forging, stamping, cutting, shipbuilding; semi-conductor industries such as diesel uninterruptible power systems, compressors, compressed gas production. Transportation industry such as ship turbines, diesel engine rooms, airport ground crew, aircraft maintenance personnel. Construction sites such as excavators, pile drivers, large screw factories, metalworking factories, etc.

The PRO filter has a unique two-way conduction feature that dramatically reduces the "blocking effect" of wearing earplugs, allowing you to hear your own natural voice when you speak. The two-way conduction also keeps the ear canal well ventilated and comfortable. 
(The blocking effect is the feeling that the sound of your own voice echoes inside your head when you plug your ear canals).

The chart below shows the PRO 31's attenuation curve. As you can see, at 115 decibels of ambient noise, the PRO 31 filter can provide up to eight hours of safe listening time. The next chart shows the safe-listening-time of different PRO model filters under different ambient sound pressures. If the PRO 31 doesn't give you enough safe listening time at your ambient sound pressure, you should add a pair of overhead earmuffs to provide a higher noise reduction factor.


Using different colored silicone and engraving, you can customize the design of your earbuds uniquely. Here are some example pictures to stimulate your imagination.
