Hi Ron.
The question is, why is the wheelchair generating sufficient
electromagnetic noise to affect the microphone system?
Have you tried other wheelchairs near the microphone?
Does it still cause interference when the chair is "off"? I did once
come across a powered wheelchair that continued to emit quite a lot of
electrical noise even though it was switched off.
Is it definitely the microphone or is it the computer it is plugged into -
ie do you still get audio interference from the sound card speakers without the
microphone plugged in?
Sorry, lots of questions, not many answers.

Hi,
I wonder if anyone has any
experience of this and can suggest an
alternative.
As recommended by a DSA assessor
we’ve supplied a copy of Dragon Naturally Speaking voice dictation software
and a Plantronics USB headset to a student who is an electric wheelchair user.
She is having great difficulty in training Dragon to recognise her voice
as there is a lot of interference, presumably from the wheelchair’s motors,
being picked up by the microphone. We’ve checked the microphone in a
room away from the wheelchair and there is no interference
there.
I guess we need to go for a
different headset, but has anyone any experience or knowledge of what type of
microphone might work without being susceptible to the
interference?
Thanks in
anticipation.
Ron
