![]() ![]() Battery-powered Active Noise Reduction (ANR).The Lightspeed PFX builds upon the already fantastic featureset of the Lightspeed Zulu 3 headset. This thing is truly a super computer among ANR controllers. Lightspeed plans to add other new sensor features to the Delta Zulu safety wearables platform.The Lightspeed PFX controller takes 4 batteries and is by all accounts a “power hog”. Lightspeed isn’t yet offering helmet applications for the Delta Zulu series, and the new headset will not be submitted for FAA technical standard order approval. “Feedforward assists in canceling sounds much further out than analog ANR.” Later this year, Lightspeed plans to offer a separate charger for offline battery charging.Īlthough the Delta Zulu headset retains the comfort features of the Zulu 3 headset, the ANR is improved with the addition of secondary “feedforward” noise cancellation, which adds more breadth to noise cancellation, according to Schrader. While spare batteries are available, the Delta Zulu headset can also run on AA batteries for 15 to 20 hours. The included lithium-ion battery lasts about 30 hours on a charge but can be charged while using the headset. It also comes with a universal accessory connector plug with connections for USB-A and -C, 3.5mm, and Apple Lightning (some are optional). The new headset is available with plugs in dual general aviation, Lemo panel power, and U-174 configurations. Bluetooth wireless is included for cellphone communications, stereo music streaming, and audible alerts from aviation apps. Pilots can also use the Lightspeed app to record radio conversations, listen to radio call playbacks, save flight audio recordings for debriefing, and draw diagrams. This will make quite a difference in your experience.” As the processor encounters areas where you might have a deficiency, it begins to profile that and boosts the frequency where you have a deficiency. “You’re led through a sequence from 125 to 12,000 Hz in one ear then it switches to the other. “You take a hearing test with the headset,” said Lightspeed founder Allan Schrader. Each headset can be set to multiple audio equalization profiles for more than one user. ![]() ![]() Once completed, the audio equalization system sets the hearing level in each ear cup “to create your individual hearing profile to compensate for any hearing variations between ears,” according to Lightspeed. With the HearingEQity audio equalization system, pilots can use the Delta Zulu headset and app on the ground to run through an automated 12-frequency hearing test. The headset’s audible alerts warn when it detects CO above caution and critical levels (10 to 50 and 50 to 100 ppm, respectively), but pilots can also view CO levels and history on the Lightspeed app. The first sensor incorporated in the headset is Lightspeed’s Kanari “smart alert technology” for measurement of carbon monoxide (CO) levels. Headset manufacturer Lightspeed today announced its newest headset, the Delta Zulu, which is the first of the Oregon company’s new line of “safety wearables.” Not just an active noise-canceling (ANR) headset, Delta Zulu adds new safety sensor capability and audio equalization to improve cockpit audio for pilots with hearing loss. Delta Zulu is priced at $1,099 and will begin shipping later this month. ![]()
