We are looking for a vendor to provide a Digital Intercom for the purpose of an operator to be able to communicate with a patient in a hazardous location. Where the patient is located is an oxygen enriched environment where the gas-noise level is high. There will need to be some type of active noise isolation or digital signal processing to clean up this signal and provide great audio performance. Additionally, we would like to incorporate some Bluetooth into the system so we can transmit entertainment audio to multiple devices in the same room without having to run individual cables to each intercom. I can provide more details upon request.
