    Hey, i have two microphones I'm looking to use for work with our AVAYA phones.

    I'm trying to decide which will be better.

    Here are the specs:

    Mic A:

    Sensitivity: -40 ± 3dB
    Impedance: Max. 2.2 ㏀
    Standard Power Supply: 2.0 V DC
    Current Consumption: Max. 0.5 mA
    Sensitivity Reduction: Within-3dB at 1.5V
    S/N: More than 58dB
    Omnidirectional


    Mic B:

    Headphone frequency response : 20Hz to 20kHz (20Hz to 8kHz with +\- 10% variance)
    Headphone impedance : 16 Ohms
    Transponder frequency response : 20Hz to 20kHz
    Headphone power : 5mW (Max 10mW)
    Transponder sensitivity: -46dB +/- 3dB
    Throat-Mic


    I can not figure our which is better or more sensitive. The problem we are currently having is that the HW261N headset we are using pick up just about everything and we can not have that in a call center.

    I would of thought a high quality throat-mi mic be the best. Omnidirectional is the right type but i find who evers support line i call has some background noise regardless..

    Why not get some one else help you with it and have them phone you to test it..

    the problem is I can not figure out which is going to be better at picking up sound. not in the omni-directional sense but in the Im speaking, it hears me sense.

    The part im trying to figure out is: -46db vs -40db. which is better? the Throat-mic transponder(mic) is -46db +/- 3db this is sensitivity.

    This is the throat mic:

    -46dB is more sensitive.

    However, take all manufacturer-provided specs with grain of salt...

    Thanks, that is what i thought. so the throat mic is more sensitive? I have the Zalman M1 from the Specs for Mic A.

    That picks up damn near everything.

    The Throat Mic has the -46db +/- 3db.

    The mic should be able to discern when someone is talking and not everyone around them.

    I used to use them in the cadets ( when i was living in the UK ) when i was younger and they are good due to being right next to our voice box although i found that you don't sound quite like you but i guess that don't matter even more so in our case.

    You cannot use the specifications listed in #0 to conclude which is best.

    One is a throat mic one is a omni-directional one. Completely different principles therefore a specification comparison is irrelevant. Like apples and oranges.

    throat mic is less likely to get background noise. but it could still be utter crap, you need to get one and test it.

    it is on my list of things to do.

    I found the adapter to connect to the phone with. it is a 3.5mm to RJ10/RJ9 adapter.

    Do you think the Iasus one is better than the Stryker one?

    impossible to tell. i suggest picking three, ordering one of each and getting people at hte workplace to test them. most popular goes.

    one could have fantastic specs, awesome quality... and not fit the necks of your steroid taking lumberjack sized workers. you just wont know without testing.

    Im the only one doing the testing so I think the Iasus one looks best if the reviews say anything...

    those reviews seem to indicate it could be good. your voices will sound odd, but you wont get anywhere near as much background noise.


    and you could even be a TV presenter! wow!

    My College major was broadcasting before i change it to English.

    I was training to be Master control Operator.

    They said when i did on camera work, that i could do very well but expressed too much emotion .

    Throat mics usually have more static due to the higher gain used, but the obvious benefit is that they are not affected by background noise like the omnidirectional is. The omnidirectional will probably make your voice sound more natural thus improving speech intelligibility. If one company has both they might let you try them both and send back the one you do not want.
