We've seen this in the past when using music as the external sound, but never with simulated office noise which is very random. Yes, this microphone actually provided better numbers in this artificial environment in the presence of external noise. Here's what I found with the PowerMic II and PowerMic III:Īccuracy: 65-70 dB simulated office noise: 99.1% It involves creating a new profile for each microphone to be tested. The point of this whole protocol is to minimize any bias from the testing process and use the exact same voice and environment when testing each microphone. Bench Testing: In the ultimate show of my OCD tendencies, I have gone to the trouble of setting up a formal testing protocol which uses a 'virgin profile' created solely with pre-recorded speech for profile set-up and pre-recorded readings of the 'Rainbow Passage' and with multiple recordings done both in quiet, and in the context of 65-70 dB contaminating 'recorded office noise'.cord is a great improvement! Even though I intended to use it just for a road test, it's the mic I'm carrying in my computer case these days. While it's accuracy was impressive, where it really excelled was in external noise rejection (see discussion below). Real Life Usage: In the setting of a physician dictation room with regular conversation and dictation in the background, it worked every bit as good as my old SpeechMike Premium.

Here's what I can tell you from both 2 weeks of usage and from formal 'bench testing': In terms of size, it's about the same width, but clearly a bit shorter (see images below).Īccuracy and External Noise Rejection: While comfort, functionality and compatibility with work-flow are often key drivers for hand-held microphone users, at the end of the day a microphone has to be accurate to be viable.Since the previous pointer stick was a clear weak point, this is a significant improvement. It replaces the prior 'pointer stick' with an optical device to control cursor movement.Unfortunately, they are not interchangeable, so you have to choose one or the other at the time you purchase. It offers the choice of two cord lengths: 9 ft.

Key changes/improvement include the following: This is an upgrade of the PowerMic II hand-held USB mic which has been the preferred mic for many Dragon Medical users over the years given its convenience and integration with every medical version of Dragon since 10.

Dragon medical users may be interested to hear that Nuance has finally released the long-awaited 'PowerMic III'.
