PA-1161 Passive headsets cancel wide-ranging by blocking sound waves. Sound can be blocked by 3 methods: Barriers, Absorption Material, and Restraining Methods.
ANR Headsets
All our ANR Headsets feature the PILOT Direct Noise Canceling System. This robust system directs noise canceling toward the lower frequencies more than any other ANR headset on the market. Embedded in our ANR technology is an Enhanced Voice Intelligibility (EVI) circuit. EVI enhances speech frequencies by 2-4 dB on all audio input. This unique combination of noise canceling and speech enhancement gives our range of ANR headsets increased intelligibility using cutting edge technology.
