Look for DNR functionality on only the most high-end ANR headsets.Īviation headsets come in three styles: over-ear, on-ear, and in-ear. DNR headsets scan for repetitive identical noise signals on the transmission and then suppress just those portions of the signal. Expect to pay significantly more for an ANR headset than you would for a PNR one.ĭynamic noise reduction headsets take ANR headsets one step further by digitally removing unwanted noise from incoming headphone signals. The more advanced technology comes with a correspondingly higher price tag. In plain English, that means that the incoming soundwave and the outgoing soundwave cancel each other out, and the offending noise is eliminated. When the microphone of an ANR headset picks up a noise within the spectrum it is designed to reduce, it triggers a small speaker to broadcast a sound wave on the same frequency as the noise but with a 180-degree phase difference. Higher frequency sounds are not reduced, so your radio transmissions and on-board conversations can still be heard. These sounds typically fall between the 20Hz and 300Hz range of the spectrum. The microphones of ANR headsets are designed to reduce mainly lower frequency noises generated by engines and turbulence. Some higher-end models improve the sensitivity by positioning mics both inside and outside. They electronically monitor incoming sounds using a tiny microphone which can be placed inside or outside the ear cup. ANR headsets require a power source (usually batteries located in the earpieces or on the wires). You may also see them referred to as electronic noise canceling (ENC) headsets. The next step above PNR headsets is ANR or active noise reduction headsets. These headsets are the least advanced and the most affordable type of headsets on the market. Since a PNR headset must form a protective seal around your ear to offer protection, all PNR headsets are over-ear rather than on-ear or in-ear models. Headsets using this means of ear protection are called passive noise reduction or PNR headsets. This is achieved by erecting a barrier around your ears in the form of ear cups and seals. The most basic low-tech version of noise reduction is to physically stop the unwanted sounds from entering your ears. The most common types of noise reduction are passive noise reduction and active noise reduction, with some higher-end headsets also using dynamic noise reduction. One of the main criteria that differentiate headsets is the type of noise reduction measures they use. This will narrow your search results to only the headsets that are the best fit for you.Ĭonsider the following variables when picking an aviation headset:

There are so many brands and styles of headsets to choose from, plus a slew of features that can easily seem overwhelming at first.īefore you aimlessly click through pages upon pages of potential options, decide what features you are looking for. You’ve decided to skip the grunge factor and purchase your own piloting headset. What features to look for in an aviation headset Sure, you can wipe them down and try to sanitize them, but do you really want to mess around with that bacterial breeding ground when you could avoid it altogether? This is why it just makes sense to secure your own personal headset. Now imagine wearing someone else’s snorkel mask, earbuds, or baseball cap that they have already sweat in. A used entry-level headset is likely to be uncomfortable and potentially ill-fitting.
They will have already sustained plenty of wear and tear from other students. While a rental or loaner may be possible, at least to get started, for most pilots, it still makes sense to purchase your own headset even if your budget can only support an entry-level model.įor starters, the communal headsets that you may find through a school will probably not be the best aviation headset and certainly won’t be the top-of-the-line models. None of us enjoy purchasing something we don’t really need, so the first question many new pilots ask when scanning a recommended gear list is, “Do I really need to buy my own headset? Can’t I just rent or borrow one from my school?” They also offer hands-free communications with ATC and passengers, making it even more appealing to fly with a headset. This means it’s time to reach for hearing protection in the form of a pilot headset.Īviation headsets provide more than just hearing protection and decreased cabin noise though. However, The FAA Hearing and Noise in Aviation safety brochure reminds us that sound levels in a small single engine cockpit can reach 90 dB, and sustained exposure to noise over 90 dB can cause permanent hearing loss.
