NOISE CANCELLATION


How much noise reduction does the Bose A30 Aviation Headset provide? What is the attenuation at different frequencies?

The Bose A30 Aviation Headset provides three modes of user-selectable noise cancellation that were individually engineered for specific use cases. “Low” helps optimize interpersonal communication outside the use of an intercom system. “Medium” provides the most consistent amount of reduction across a wide range of frequencies, and “High” provides the most active noise reduction to maximize the signal-to-noise ratio for radio communication. All three modes have been engineered for distinct uses.


Bose does not make claims about the mode of noise reduction. We encourage pilots to try the product in a variety of aircraft to experience the dramatic performance and capability of each mode for themselves.


What is the EPA-rated attenuation of the Bose A30 Aviation headset?


The current methods specified by the EPA Noise Reduction Rating (NRR) cannot be applied to active noise-cancelling devices. The EPA is currently redefining the NRR, with an explicit goal of including active noise-cancelling devices in its scope. In addition, the latest TSO standards identify the latest ANSI test standards relating to active noise reduction headsets, which Bose both contributes to and complies with.


Does it have an audio output limiter like Sennheiser’s “peak level protection”?


No, there is not a limiter. All headsets provide output up to 110dB, per TSO requirements.


Does Bose offer noise cancelling in helmets for pilots or motorcycles?


Bose does not offer active noise reduction within helmet systems. Bose is always researching ways to solve problems with innovative technology offerings.


What is talk-through tap control?


Double tapping an earcup in high or medium ANC modes will shift that earcup into low mode, enabling voices outside of the intercom to be heard more easily. If the earcup is already in low mode, then tapping will not change the setting.


Do I need special permission to use this headset on my airline? Are STCs required?


Airline requirements vary greatly. Some allow pilots to use headsets of their choice while others require an approved list of products.


Can a hearing aid be worn under or inside the earcup?


Consult your audiologist. Many hearing aids create feedback when amplified sound escapes the ear and is picked up by the device’s microphone. By placing an object near the hearing aid – such as a cupped hand – the amplified sound is reflected to the microphone, making the device more likely to “whistle.” While many modern hearing aids suppress feedback with digital signal processing, a headset around the hearing aid can result in sustained feedback.


Because hearing loss varies from person to person and across different frequencies, removing the hearing aid and increasing the headset volume may not be sufficient. Consult your audiologist to determine the best configuration for audio intelligibility and the safe operation of the aircraft.


COMFORT


What makes the A30 Aviation Headset so comfortable?

Overall, the Bose A30 Aviation Headset is one of the smallest, lowest-clamping and lightest around-ear active noise-cancelling headsets on the market – it’s a balance of function and comfort without sacrificing stability.


The headset’s angled earcups follow the contours of pilots’ heads, and the intentional shape of the headband pads help achieve the highest level of comfort in the lowest possible on-head weight. Additionally, the A30 has distinct left and right earcups with a quick release and a side swappable mic for improved comfort and ergonomics.


What attributes make Bose cushions better?


The materials of the headset cushions were chosen for their soft feel and stable fit. The headband cushion provides the exact amount of force needed to distribute weight and pressure across the head to avoid hot spots or bottoming out.


Have the ear cushions and headband been tested for health, safety and long-term use? Have there been any tests regarding skin reactions or test certificates?


Bose does extensive tests to ensure the products we create do not cause skin irritation. When possible, Bose chooses materials that yield the best results for biocompatibility.


Can the new headset be worn when pilots suffer from auditory eczema (exostosis)?


The materials in Bose headset cushions have remained consistent for years with tens of thousands of units in operation without significant issues. In any case, customers with skin conditions should consult a doctor for advice.


What is the weight of the headset without cables?


The total headset weight is 524 grams (18.48 ounces). The on-head weight (including the headphone and half of the upper cable with boom mic) is 404 grams (14.25 ounces).


Is it legal to use a Bluetooth® device in the cockpit?


Yes, but pilots are personally responsible for permitting and utilizing personal electronic devices or any devices that emit radio signals. Depending on the country, circumstance and use case, different methods of qualification and approval may be required.


How do I record audio to and from the headset?


Audio is best recorded with the help of separate devices, applications and adapters between the headset and the aircraft to optimize performance. This includes adapters that overlay the recorded audio with video.


How do I control the volume of Bluetooth® audio?


Pilots can control the volume from the Bluetooth®-connected device or via volume controls on the side of the control module.


What is customizable audio prioritization?


Priority switching allows pilots to customize their audio sources. There are two options for audio prioritization:


Mute: When the switch is in the top position and an intercom signal is detected, all secondary audio sources are muted (streaming Bluetooth® and wired auxiliary inputs).

Mix: When the switch is in the middle position and an intercom signal is detected, Bluetooth® audio is mixed with the intercom audio. (Phone calls are always mixed.)


How does customizable audio prioritization work?


The control module has three user-defined prioritization states:


  • Mixed audio position: The intercom signal will mix with the auxiliary audio input signals.

  • Muted audio position: The auxiliary input signals will be muted when an ICS signal is present.

  • Off: Auxiliary audio sources are completely turned off to ensure sterile cockpit operations.

Note: When a Bluetooth® call is present, the audio from the call will always mix with the ICS signal. The Bluetooth® function is always disabled in the passive mode and when battery life indications are red/low.



What kind of microphone does the Bose A30 Aviation Headset have?

The A30 uses a noise-cancelling electret microphone (often called a high-impedance microphone), which is typical for aircraft. It is optimized to reject far-field noise and improve performance when used with “hot mic” systems. A 5-ohm and a 150-ohm dynamic microphone are available in specific configurations.


What is the battery life of the Bose A30 Aviation Headset?


The A30 operates for a minimum of 45 hours from two AA alkaline batteries in typical aircraft noise. With continuous operation of the Bluetooth® function, battery life will last 25-plus hours. As always, battery life varies with the type of battery, noise environment and features used during flight. The headset has a battery life indicator light to signal when batteries need to be replaced.


Can I use rechargeable batteries?


Yes. However, flying-time battery life may be lower than the acclaimed 45-hour life, depending on the type of battery chemistry used. Rechargeable batteries may also alter the accuracy of the battery status indicator light; when the light changes to amber, pilots will likely have less than eight hours of flying time remaining.


Can I use lithium-ion batteries?


Multiple battery chemistries can be used, including lithium-ion batteries. Pilots should be aware that the battery life indications may vary based on the type of batteries used.


How are the batteries installed?


The two AA batteries fit lengthwise in the bottom of the control module. To access the battery compartment, push down and slide the cover toward the headset. After the cover has cleared the detent, lift it into a vertical position and insert the batteries.


What is flexible power?


Flexible power is a feature available for headset configurations that allow aircraft power. This feature allows pilots to switch seamlessly from aircraft power to battery power. If needed, adapters to connect the headset to the aircraft are available for purchase from Bose or third-party manufacturers.


How does the auto-on feature work?


Headsets that can use aircraft power (6-pin LEMO and 5-pin XLR) will automatically turn on when aircraft power is present. A configurable switch inside the control module can disable this feature based on user preference.


How does the automatic shutoff feature work?


The automatic shutoff feature detects when the A30 is not in use and shuts off after several minutes (ranging from 6 to 45 minutes of inactivity) to preserve battery power.


Can I use the Bose A30 Aviation Headset to listen to audio from a Bluetooth® device even when I am unplugged from the intercom?


Yes. As long as the headset is turned on, audio can be played through the Bluetooth® connection. However, Bluetooth® audio will not play when there are less than two hours of battery remaining in the headset.


The Bluetooth® capability is available when the headset is turned on and the priority switch is set to either “mix” or “mute.”


What does the blue or purple light mean on the Bluetooth® module?


The blue and purple lights on the Bluetooth® module indicate the status of the Bluetooth® functionality. A purple flashing light indicates that Bluetooth® is on and the headset is discoverable or pairing but not yet connected to a device. A blue flashing light indicates that Bluetooth® is on and connected to a device.


How difficult is it to install a flex-powered version into my aircraft, and how much does it cost?


The process depends on the aircraft and where the aircraft connector would be installed. The system consists of six soldered wires: two audio, two microphone, a ground wire and a power wire. Installing near the existing phone and mic jacks is a quick process because four of the six wires can be attached directly to the back of the jacks. This also allows existing jacks to still be used with conventional headsets.


Why is the battery-powered control module the same size as the installed, aircraft-powered control module?


Installed, or aircraft-powered, versions of the Bose A30 contain a feature called flexible power circuitry. Headsets with flexible power circuitry can be powered by the aircraft or by batteries. This allows users the flexibility of battery power with an adapter cable. Because batteries take up to 70% of the control module space, the modules were designed to be the same size. The adapter cable is useful if you fly in other aircraft without an aircraft-powered connector, or if you want to disconnect from the aircraft for a quiet flight with active noise reduction.


Do the aircraft-powered versions (6-pin LEMO and 5-pin XLR connectors) require batteries for any of the functions?


No. These versions of the Bose A30 Aviation Headset do not require batteries for any function when connected to the aircraft. However, if you have batteries in the module, you can continue to use the headset when it is disconnected from aircraft power. For example, you could make a private phone call with the Bluetooth® version of the headset by disconnecting from the panel. It also enables you to use a small adapter cable to fly in other aircraft instead of purchasing a new down cable with different connectors.
