Honeywell Impact Sport by Howard Leight keeps wearers protected from hazardous noise and connected to their environment. Impact Sport employs built-in directional microphones that amplify range commands and other ambient sounds to a safe 82dB, providing more natural listening and enhancing communication. For protection, Impact Sport actively listens and automatically compresses amplification when ambient impact sound reaches 82dB, and passively blocks out noise at 22dB.
