Shopping for pilot headsets can quickly become confusing, especially for the new or less technologically inclined pilot. There are so many factors to consider: on-ear vs over-ear headset, plug type, and active noise cancellation vs passive noise reduction, to name a few.
The good news is that plug type is determined for you based on your aircraft, and on-ear vs over-ear is a mainly a matter of personal preference. The variable that deserves some additional research and consideration is noise reduction type.
In this article we will explore the differences between noise reduction types, do a cost-benefit analysis of active noise reduction technology, and share some of our favorite active noise reduction headset models.

What is the Difference Between ANR and PNR?
Pilot headsets use several different types of noise reduction designs: active noise reduction (ANR), passive noise reduction (PNR), and dynamic noise reduction (DNR).
You may also see these technologies referred to as active noise cancellation (ANC), passive noise cancellation (PNC), and dynamic noise cancellation (DNC).
The important thing to know is that all pilot headsets reduce ambient noise and protect your hearing in some way. The difference between these headset types is the method they use to offset unwanted sounds, and the effectiveness of the noise reduction provided.
What is Passive Noise Reduction?
The most common and basic type of noise cancellation is achieved by physical means through passive noise-reduction.
Passive noise cancellation headsets use a physical barrier of padded, tightly fitted earcups to block out ambient noises. PNR/PNC designs do not require batteries and due to their simpler design, these headsets are priced lower than their ANR/ANC counterparts.
What is Active Noise Reduction?
Unlike passive noise reduction headsets which physically reduce noise by muffling it, active noise reduction headsets eliminate it nearly entirely. Active noise reduction is achieved through electrical means.
Instead of merely dampening noise, an ANR headset actively eliminates ambient sounds by generating an offsetting cancelling frequency. An ANR headset requires batteries to operate, and the sophisticated electronic technology involved correlates to a higher price point than the more basic passive noise reduction headsets.
How does ANR Work?
ANR headsets work by first picking up the sound waves of external noise sources through miniature earcup microphones. The headset then electronically produces a sound wave of the same amplitude but an inverted phase to that of the external noise source.
The generated inverted wave can be referred to as an “anti-noise” signal or phase flipping. Then the sound wave from the headset merges with the sound wave from the noise source, the result is an effective cancellation of the perceivable noise volume.
Most ANR headsets will reduce target noise by 10-20dB. It is worth noting than an over-ear ANR headset design will include a measure of passive noise reduction as well simply due to its design.
What is Hybrid Noise Cancellation?
Hybrid noise cancellation is an advanced variation of active noise cancellation. Most active noise cancellation headsets use a microphone either inside or outside the earcup to pick up the soundwaves from surrounding noise.
A feedforward ANR headset has an external microphone and does well with negating high-pitched noises but is less effective on lower frequencies. On the other hand, a feedback ANR headset uses an internal microphone that does well with low-end humming noises but does not completely eliminate sounds in the upper mid-range.
The difference with a hybrid ANR headset is that it uses both internal and external microphones. This allows a hybrid headset to offer a broader spectrum of noise cancellation.
What is Dynamic Noise Reduction?
The most advanced and least common pilot headsets are dynamic noise reduction (DNR) models. These headsets digitize signals in a numerical series then scans and removes any repetitive noise components of the signal.
DNR technology works on frequencies up to 3,500Hz. Expect to pay as much as $1,500 for a digital noise reduction headset.
Is Active Noise Reduction Worth it?
ANR headsets provide the very best in hearing protection for lower frequency noises below 1-2 kHz like aircraft engines, offering much better results than passive noise reduction headsets for this frequency range.
Active noise reduction headsets also allow pilots to listen to radio transmissions and music at a lower volume, unimpeded by external noise.
Since they block frequencies below 300Hz but allow you to hear other frequencies, ANR headsets provide hearing protection without the compromise of muffling other important sounds like cockpit alerts or the sputtering of an engine.
The potential downside of active noise reduction headsets is their higher price point compared to passive noise reduction headsets. That said, if well-cared for, ANR headsets have a long lifespan giving pilots many years-worth of quality hearing protection and auditory comfort.
When the price is averaged out across the lifespan of the headset, the yearly cost of an ANR headset investment is nominal.
Due to cost constraints, a new student pilot on a budget may elect to purchase a PNR headset initially and then upgrade to the ANR model later. Eventually, most pilots do opt for the enhanced performance provided by an ANR headset. Just remember to hang on to your retired PNR headset as it will work perfectly well for passengers.
What to Look for in an ANR Pilot Headset
Before you jump into shopping, ask yourself a few questions and make a list of the features that are important to you. Here are a few things to consider:
- Will you want a headset that has Bluetooth functionality?
- What earcup and headpad materials do you find most comfortable for long-term wear?
- What type of aircraft will you be using the headset in? Do you need more than one type of plug so your headset can work in both helicopters and GA fixed wing planes?
- Do you want to upgrade to dynamic noise reduction or stick with a standard ANR model?
- What is your preferred price range and what is your maximum price point?

While I love ANR technology, the one drawback that I have found is you can’t hear what the airplane is doing, especially the engine. Many times, you will hear what the engine is doing before you can see it on a gauge (if you get an indication at all). I prefer passive noise reduction because it allows me to monitor all aspects of flying the airplane from engine noise, open doors and windows, cargo doors slapping in the slipstream, etc. while still allowing me to monitor the radios and other auditory indicators. For me, passive headsets help me with the safety of flight.

OK, here’s the “deal” with ANR; while the noise *cancellation” is usually excellent, the noise *protection” to the ear continues to be “suspect.” An ANR set does not claim to be protective against physical damage. Therefore, if this is a concern, it has been suggested to use ear plugs while using an ANR set to mitigate the possible long term physical damage to the ear.
One more thing: there are some sounds a pilot should be hearing, like sounds an engine makes if it is about to fail.
ANR presents a problem not unlike polarized glasses when looking at some instruments on the panel – they black out when viewed at certain angles.
