David clark vs bose aviation headset11/6/2023 My over-the-head headsets perform great, even for my longer 10 to 13 hour flight days. I’ve owned or tested almost all makes of Bose, Lightspeed, David Clark and others. Over my career, I’ve used an assortment of designs and brands: earplugs, regular over-ear headsets, ANR. Once you are ready to return to your previous ANR setting, simply tap twice again on the ear bud.įrankly, if a headset isn’t comfortable, pilots aren’t going to use it for long – no matter the whiz-bang features it proclaims to offer. This eliminates the need to remove your earbud or fiddle with your noise reduction settings. If your ANR settings are set to “Med” or “High”, tapping twice on either ear bud instantly lowers the ANR to “Low”, allowing for easier hearing of any sound such as a passenger talking. Bose incorporated instant ANR reduction by way of double tapping either ear piece. Tap Twice for Your Passengers or Co-Pilot In the other two settings, “Med” and “High,” the attenuation profile changes progressively, with maximum attenuation of all frequencies experienced in the “High” profile.īose incorporated instant ANR reduction by way of double tapping either ear piece. In the “Low” setting, external bass frequencies are attenuated while med and voice frequencies appear to be enhanced or amplified. Rather than a flat reduction of sound levels across the frequency sound spectrum, each profile is customized to provide attenuation at specific frequencies. The ProFlight headset achieves its proprietary noise reduction by incorporating three acoustic profiles, each tuned to a particular combination of frequency attenuations or cancelling. I’ve found through my testing that the noise level in most light jets is around 80-86 dB, while turboprops like my Meridian are 96 dB and high performance pistons, such as the SR22, are closer to 100 dB. Where the ProFlight shines is in its unique ANR design for lower noise cockpits found in turboprop and turbine aircraft. This is one reason Bose does not directly market this headset for noisier aircraft. Though the ProFlight’s ear buds provide some passive noise attentuation, it does not match the same level of passive noise reduction of the full size, over-the-ear headsets like the A20. Each are tuned to a particular combination of frequency attenuations or cancelling. The ProFlight headset incorporates three acoustic profiles: Low, Med, High.
