Hello Jan,
I read with interest all the material on your website regarding the tbone Aviation Headset, but could not find any answers to the following questions I have:
- Is the headset battery powered? The inclusion of an amplifier module suggests to me that some form of power source is required. What type of power source does the headset use? How long does it last? What happens when the powersource runs out? Will the headset still function in some fashion, or does a spare battery/headset need to be carried?
- Is the output power of the loudspeakers limited in any way? ie. Will the amplifier module prevent hearing-loss inducing levels of sound from being injected into the user's ear?
- What is the level of passive attenuation that the headset achieves? I understand that there is a speech frequency acoustic filter built in to the design, but how would hearing protection compare to say a set of ear muffs or standard ear plugs (noting the brochure shows pilots conducting walk-arounds wearing the headset) ? Would the level of noise attenuation make the headset suitable for noisy cockpits, eg light aircraft ?
Thanks,
DD
