  1. Noise reduction of various headsets(How they hear your voice) Tested in 91 dB SPL Babble Noise Tested in 87 dB SPL Jeep Noise LAB LIVE? Typical BT headset performance Typical BT headset performance

  2. ETY-COM and etyBLUHeadset Demo(well-sealed ear = 30-40 dB isolation) Typical (mostly unsealed) headset EtyCom (or etyBLU) headset How you hear their voice in a very noisy car: With a Typical With an etyBLU or ETY-COM Headset Earphone Headset Earphone at maximum volume

  3. The science behind:11+5 = 16 dB effective noise reduction from BLUmaxx™ noise-canceling micdesign etyBLU theoretical noise-canceling performance 14 dB increase in signal from placing microphoneclose to mouth(e.g., landline phones or RAZR flip phone)

  4. Double check in Red Telephone Booth at MacWorld with newly purchased Jawbone on MCK. etyBLU (Boom mic) Jawbone Simultaneous recordings: etyBLU on right ear, Jawbone on left 90 dB SPL Jeep noise 100 dB SPL Jeep noise Non-simultaneous recordings but same vocal effort 80 dB SPL Restaurant noise 90 dB SPL Restaurant noise Note: The recordings were made by pairing the Jawbone to my 847-609-5598 (“609”) RAZR phone and the etyBLU to my 847-309-5598 (“309”) phone and calling the other phone’s voice mail (by not answering the call). Later, the voice mail was played back into an earphone (wired ETYCOM) sealed into a coupler whose microphone was fed to Cool Edit on my A31 notebook.
