The Pros and Cons of ANR Headsets
There are two basic types of pilot headsets in the world of flying. There are passive noise reduction headsets and active noise reduction (ANR) headsets. This article discusses the pros and cons of ANR aviation headsets.
Advantages of ANR headsets
The most obvious benefit of ANR headphones is their unusual ability to almost completely eliminate the engine, propeller and air noise found in most aircraft cockpits. This allows the pilot to clearly hear and understand communications sent from the control tower personnel and other controllers.
Another benefit of using headphones with active noise cancellation is protection against hearing loss. Continuous exposure to high decibel sounds in airplane cockpits can cause permanent hearing loss in pilots. Although passive noise canceling headsets will also prevent eardrum damage, ANR headsets do a better job.
Active noise canceling headphones are lighter and have less clamping pressure than passive noise canceling headphones. Passive noise canceling headphones rely only on a seal around the ear to reduce noise. This means that the shells must press firmly against the head, which requires pressure. This constant pressure on the sides of the head can cause fatigue and headaches for the pilot.
Another advantage of ANR headsets is the ability to wirelessly connect a mobile phone or MP3 player to the headset. These connections are made using Bluetooth technology. The pilot doesn’t have to take off his headphones to make a quick call before takeoff or after landing. And it’s also nice to listen to music during less busy times of the flight.
Disadvantages of ANR headsets
ANR headsets are more expensive than passive headsets, with most costing more than $1000. This can be a strong deterrent for people on a budget.
What makes them so expensive is the advanced technology necessary to eliminate noise in the cockpit. Basically, it has to do with creating sound waves that are in direct opposition to the sounds being picked up by the headset and sending those sound waves back to the pilot, canceling out the background noise.
Like other electronic products, manufacturing costs are falling, but they are still expensive enough to make a pilot think twice before buying one.
Another disadvantage of ANR headsets can sometimes be prone to malfunction due to their high-tech nature. And you must always have new spare batteries with you.
In conclusion, every product has its pros and cons, so it is up to the individual to weigh the pros and cons and make a purchase decision based on that.
