Air Mask Microphone
The client needs to wear a positive air pressure mask which covers her nose and mouth at all times, but the mask makes it difficult for others to hear her when she speaks.
The Challenge
The Client wears a positive air pressure mask at all times. This makes it difficult for people to hear what she says.
The solution
A miniature microphone was fitted to the mask and an amplifier-speaker constructed. The amplifier can be powered either by a battery or by an external plug-top power supply.
The benefit
The client can now be heard more clearly by those around her when she speaks.
