Product Description

CCBX 536 Sound Pickup Active Noise Canceling Hearing Protector

This is an active noise cancelling hearing protection device that requires a power source to operate. It is widely used in environments such as battlefields, engine compartments, and airport ground services where noise levels are high. When the external sound level reaches 82 dB, the protector activates and reduces the ambient noise to approximately 50–55 dB within 20 milliseconds, effectively protecting the user's hearing. When the external noise level drops below 40 dB, the device amplifies faint ambient sounds to around 50–55 dB, making it easier to identify the direction and type of external sounds.

Features

•Power on/power off
