Unfortunately, these very noise-canceling attributes also isolate the wearer from sounds that would make them aware of hazardous conditions in their surroundings. This allows any sounds generated within the headset to be understood more clearly (music, radio communications, etc.). This analog technology functions by detecting the sound coming into the headset, and generating signals that are out-of-phase with the offending signals, canceling them out. In the past, this consisted of an ear-muff-style headset, which cupped closely around the ear, basically reducing noise levels through their insulation and tight fit construction.Īs technology addressed the issue of hearing protection, active noise-canceling was developed, which provided a more effective solution.

Many of these devices have historically reduced the noise reaching the ear by means of noise-canceling technology. In many cases, this includes the wearing of headset or ear-muff hearing protection devices (HPDs).

Where occupational hazards or other high-noise-level conditions exist, it becomes important for workers and others in the immediate vicinity to take appropriate steps to protect their hearing. What are Noise Suppression and Noise Cancellation?
